Chocolate Mousse Cake Recipes

Steps:

• For the brownie: Preheat the oven to 350 degrees F. Spray the bottom of a 9-inch springform pan with nonstick cooking spray.
• Whisk together the flour, cocoa powder and sugar in a medium bowl. Whisk in the milk, butter, vanilla and egg until smooth. Pour the batter into the prepared pan and bake until a knife inserted in the center comes out clean, about 20 minutes. Cool completely on a wire rack, about 30 minutes.
• Unclasp the pan, remove the outer ring and spray it with nonstick cooking spray. Line the ring with a 2 1/2-inch-wide parchment strip, making sure that it sits tightly and smoothly along the sides. Re-clasp the ring to the bottom of the pan with the cake in it.
• For the mousse: Roughly chop 4 tablespoons of the butter and put in a medium microwave-safe bowl. Microwave in 30-second intervals, stirring in between each, until melted, about 1 minute. Stir in 1/4 cup of the cocoa powder until smooth; set aside. Chop the remaining 8 tablespoons butter and put in a medium microwave-safe bowl. Microwave in 30-second intervals, stirring in between each, until melted, about 1 minute. Stir in the remaining 1/2 cup cocoa powder until smooth; set aside.
• Add 1/4 cup of the heavy cream to a small microwave-safe bowl and stir in the gelatin. Let sit for 5 minutes to bloom. Microwave in 30-second intervals, stirring in between each, until the gelatin is dissolved, about 1 minute. Cool to room temperature, about 5 minutes.
• Transfer the gelatin to the bowl of a stand mixer fitted with the whisk attachment and add the sugar, vanilla and remaining 3 3/4 cups heavy cream. Whisk on medium speed until stiff peaks form, 3 to 4 minutes. Divide the whipped cream mixture between 2 large bowls. Fold one bowl of the cocoa powder-butter mixture into each batch of whipped cream mixture and stir until no streaks remain (one bowl will contain dark chocolate mousse and the other will contain light chocolate mousse).
• Spread the dark chocolate mousse on top of the brownie in the springform pan. Use an offset spatula to even out and smooth the top. Spread the light chocolate mousse on top of the dark chocolate mousse and use an offset spatula to even out and smooth the top. Refrigerate until the mousse is set, 3 hours and up to overnight.
• For the ganache: Bring the heavy cream and butter to a boil in a small saucepan over medium-high heat. Put the semisweet chocolate in a large heatproof bowl and pour the hot cream over top. Let it sit for 5 minutes, then stir until smooth and shiny.
• Unclasp the springform pan and remove the parchment paper from the sides of the cake. Use a hot, dry offset spatula to smooth out the sides. Set a rack in a rimmed baking sheet and put the cake on top of the rack. Pour the ganache over the cake and let it drip down over the sides so the entire cake is covered. Swipe once across the top with a clean, large offset spatula to create a smooth top. Refrigerate until set, about 30 minutes.
• Hold a stencil or other tool with holes (such as a doily or a cooling rack) over the cake (do not lay it on the ganache; it will stick) and dust with more cocoa powder to create a decorative pattern. Serve immediately.

Steps:

• Grease 9-inch springform pan line with parchment paper grease and flour paper.
• Stir water, sugar, corn syrup and flour in heavy saucepan.
• Cook on low heat until sugar is dissolved, stirring constantly.
• Add chocolate, vanilla and salt.
• Continue cooking until chocolate is completely melted stirring constantly.
• Remove from heat.

• Refrigerate 15 minutes or until mixture has somewhat cooled, stirring occasionally.
• Add egg yolks to chocolate mixture; stir with wire whisk until well blended.
• Gentle fold in egg whites.
• Fold in whipped cream.
• Spoon into prepared pan.
• Place pan in larger baking pan, then place on center rack in oven.
• Carefully pour boiling water into larger pan to come halfway up side of springform pan.
• Bake at 350°F for 50 minutes or until mixture is just set.
• Run small knife or metal spatula around rim of pan to loosen cake; cool before removing rim of pan.
• Cover top with plastic wrap; refrigerate 4 hours to overnight.
• Center will fall. A prefect bowl for berries!
• Garnish with fresh berries and whipped cream.

Steps:

• Heat oven to 350°F and coat a 15x10x1-inch jelly roll pan with nonstick cooking spray. Line with parchment paper; lightly coat paper with spray also.
• Melt chocolate in a small bowl in microwave on 100% power for 1-2 minutes; stir until smooth.
• In a large bowl, beat butter, sugar and vanilla until smooth. Beat in eggs and melted chocolate.
• In a medium sized bowl, mix flour, baking powder, baking soda and salt.
• Alternatively beat in flour mixture and buttermilk to butter mixture, ending with flour.
• Evenly spread into prepared pan.
• Bake at 350°F degrees for 25 minutes or until top springs back when pressed. Let cool in pan for 5 minutes then invert onto rack; remove pan and parchment paper; let cool completely.
• Slice cooled cake into thirds - each piece 10x5x1-inches.
• Prepare mousse following package directions ADDING cinnamon.
• Stack cake layers with 3/4 cup mousse between layers and 1 1/4 cups on top.
• Chill for 1 hour then garnish with chocolate curls.
• Keep any leftovers stored in the refrigerator.

Steps:

• Make the cake: Prepare the cake mix as the label directs for a 9-by-13-inch cake. Bake; cool slightly in the pan, then invert onto a rack to cool completely.
• Clean out the cake pan and line it with plastic wrap. Cut the cake in half lengthwise, then in thirds crosswise to make 6 rectangles. Using a serrated knife, slice each rectangle in half to make two layers. Arrange half of the pieces snugly in the cake pan. Crumble the remaining pieces and press tightly into 6 small balls; arrange 1 cake ball in the center of each cake rectangle in the pan.
• Make the mousse: Heat the chocolate, butter, coffee and 1/4 cup water in a heatproof bowl set over a saucepan of simmering water (do not let the bowl touch the water), stirring, until melted. Remove the bowl from the pan; stir until cool. Reserve the simmering water. Fill a large bowl with ice water.
• Whisk the egg yolks, 1 1/2 cups sugar and 2 tablespoons water in a separate large heatproof bowl. Set the bowl over the saucepan of simmering water and whisk until pale yellow, 6 to 8 minutes. Add the chocolate-coffee mixture and the vanilla and whisk until combined, about 2 minutes. Remove the bowl from the pan and set in the bowl of ice water; whisk until slightly cool but not thick, about 4 minutes.
• Beat the egg whites and salt in a bowl with a mixer until foamy. Add 2 tablespoons sugar and beat until almost stiff; gently fold into the chocolate-yolk mixture to make a dark chocolate mousse. Spread 5 cups over the cake and cake balls. Freeze until firm on top, about 30 minutes.
• Beat the heavy cream and the remaining 4 tablespoons sugar until soft peaks form; fold into the remaining mousse. Remove the cake from the freezer; spread with the light chocolate mousse, cover with plastic wrap and freeze until firm, at least 6 hours or overnight.
• Make the chocolate shell: Stir the chocolate, heavy cream and 4 tablespoons corn syrup in a heatproof bowl set over a saucepan of simmering water (do not let the bowl touch the water) until melted. A spoonful at a time, spread half of the shell mixture over the frozen mousse. Return to the freezer.
• Make the chocolate sauce: Add the remaining 1 tablespoon corn syrup and the butter to the remaining chocolate shell mixture. Microwave 30 seconds, then stir until glossy.
• To serve the cake, beat the heavy cream with a mixer until foamy. Add the sugar and beat until soft peaks form. Remove the cake from the freezer; invert onto a baking sheet and unmold, then invert again onto a platter, chocolate shell-side up.
• Cut the cake in half lengthwise using a warm knife, then cut into thirds crosswise to make 6 rectangles; cut each rectangle in half diagonally to make 2 triangles. Top each triangle with whipped cream, ice cream and the prepared chocolate sauce.

Steps:

• Grated chocolate, cookie crumbs or chopped nuts for coating the sides of cake, if desired
• Cake:
• Lightly coat the insides of 3 9 by 1 1/2-inch cake pans with melted butter. Line each pan with parchment paper, then lightly coat the parchment paper with more melted butter. Set aside.
• Preheat the oven to 325 degrees Fahrenheit.
• Heat 1-inch of water in the bottom half of a double boiler over medium heat. Place remaining butter and 8 ounces semisweet chocolate in the top half of the double boiler. Tightly cover the top with film wrap. Allow to heat for 10 to 12 minutes. remove from the heat, stir until smooth, and hold at room temperature.
• Place the egg yolks and 3/4 cup sugar in the bowl of an electric mixer fitted with a paddle. Beat on high until slightly thickened and lemon-colored, about 4 minutes. Scrape down the sides of the bowl and beat on high for an additional 2 minutes.
• While the egg yolks are beating, whisk 4 egg whites in a large stainless steel bowl until stiff, but not dry, about 3 to 4 minutes.
• Using a rubber spatula, fold the melted chocolate mixture into the beaten egg yolk mixture. Add a quarter of the beaten egg whites and stir to incorporate, then gently fold in the remaining egg whites.
• Divide the batter between the prepared pans, spreading evenly, and bake in the preheated oven until a toothpick inserted in the center comes out clean, about 25 to 30 minutes. Remove the cakes from the oven and allow to cool in the pans for 15 minutes. (During baking, the surface of the cakes will form a crust; this crust will normally collapse when the cakes are removed from the oven.) Invert the cakes onto cake circles, remove the parchment paper, and refrigerate for 30 minutes.
• Filling:
• To prepare the dark chocolate cream, heat 1-inch of water in the bottom half of a double boiler over medium heat. Place the semisweet chocolate in the top half of the double boiler. Tightly cover the top with film wrap and allow to heat for 8 to 10 minutes. Remove from the heat and stir until smooth. Transfer the melted chocolate to a stainless steel bowl and set aside until needed. Place heavy cream and sugar in the well-chilled bowl of an electric mixer fitted with a well-chilled balloon whip. Whisk on high until stiff peaks form, about 1 1/2 minutes. Remove the bowl from the mixer. Use a hand whisk to combine 1/4 of the whipped cream into the melted chocolate until smooth and completely incorporated. Add the combined whipped cream and chocolate to the remaining whipped cream and use a rubber spatula to fold together.
• Ganache:
• Heat the heavy cream and the butter in a 3-quart saucepan over medium high heat. Bring to a boil. Place the semisweet chocolate in a 3-quart stainless steel bowl. Pour the boiling cream over the chocolate and allow to stand for 5 minutes. Stir until smooth. Chill 1 cup of ganache for at least 1 hour. Remaining ganache should be at room temperature
• To assemble cake:
• Arrange one of the cake layers in a 9-inch springform pan, evenly spread half the filling over the cake and top with the second layer. Add remaining filling and top with the remaining cake layer. Chill 2 hours. Transfer chilled cup of ganache to pastry bag fitted with a star tip. Remove cake from springform pan and coat sides and top with room temperature ganache. Using chilled ganache, decoratively pipe stars on top of cake. If desired, coat sides of cake with grated chocolate, cookie crumbs of chopped nuts.

Steps:

• Make the cake: Preheat the oven to 350˚ F. Butter a metal 8-inch square cake pan. Line the bottom and sides of the pan with parchment paper; lightly butter the parchment. Combine the cocoa and espresso powders in a medium bowl. Heat the milk and butter in a small saucepan over medium-low heat until the milk is steaming and the butter melts. Whisk into the cocoa mixture; let cool to room temperature.
• Whisk the flour, baking powder, baking soda and salt in a medium bowl. In a large bowl, beat the eggs and sugar with a mixer on medium-high speed until very pale, thick and pillowy, 5 to 8 minutes. Beat 30 to 45 more seconds to stabilize the egg foam.
• Reduce the mixer speed to low; beat in the cocoa mixture in 2 additions, alternating with the flour mixture in 2 additions. Beat just until the batter is smooth and no dry flour remains.
• Pour the batter into the cake pan and gently tap against the counter to eliminate any air bubbles. Bake until a toothpick inserted into the center comes out clean, about 35 minutes. Let cool 10 minutes in the pan, then turn out the cake onto a rack. Peel off the parchment but let it rest gently on top of the cake while it cools completely. Wipe the cake pan clean and reserve.
• Make the ganache: Combine 1/2 cup heavy cream, 4 ounces chocolate and 1 tablespoon butter in a small saucepan. Gently cook over medium-low heat, stirring, until melted and smooth. Let cool.
• Make the mousse: Combine the remaining 4 tablespoons butter and 4 ounces chocolate in a small microwave-safe bowl. Microwave in 30-second intervals, stirring, until melted and smooth. Whisk in the cocoa powder until smooth. Let cool.
• Meanwhile, combine 1/4 cup heavy cream and the gelatin powder in a small microwave- safe bowl. Let stand until the gelatin absorbs the liquid, about 5 minutes, then microwave until melted, 20 to 30 seconds, whisking. Let cool, stirring occasionally.
• Combine the remaining 1 1/4 cups heavy cream, the sugar and espresso powder in a large bowl. Beat with a mixer on medium speed to dissolve the sugar, about 1 minute. Stream in the cooled gelatin mixture, then increase the speed to medium high and beat until the mixture is thick and stiff peaks form. Fold in the cooled chocolate mixture in 2 or 3 batches until the mousse is well blended.
• Assemble the cake: Line the reserved cake pan with 2 crisscrossed strips of parchment paper (this will help you lift out the finished cake). Carefully slice the cake horizontally into 3 equal layers. Lay the best layer cut-side up in the bottom of the pan and brush with some of the chocolate liqueur, if using. (Use a plate or small cutting board to move the layers; if your top cake layer is domed, use it for the middle of the cake.) Evenly spread half of the mousse on top with an offset spatula, all the way to the edges. Top with a second cake layer. Brush again with chocolate liqueur, then spread half of the ganache evenly on top. Add the final cake layer, cut-side up, and brush with the remaining liqueur. Top with the remaining mousse and ganache. (The assembled cake should fill the pan.)
• Refrigerate the cake until the top is set, about 30 minutes, then wrap the whole cake pan with plastic wrap and refrigerate overnight to set completely.
• Lift the cake out of the pan using the parchment pieces and transfer to a cutting board. Using a hot, dry serrated knife, slice the cake, wiping the knife in between cuts for clean edges.

Steps:

• Lightly coat the insides of 3 (9 by 1 1/2-inch) cake pans with melted butter. Line each pan with parchment paper, then lightly coat the parchment with more melted butter. Set aside.
• Preheat the oven to 325 degrees F.
• Heat 1-inch of water in the bottom half of a double boiler over medium heat. Place remaining butter and 8 ounces semisweet chocolate in the top half of the double boiler. Tightly cover the top with film wrap. Allow to heat for 10 to 12 minutes. Remove from heat, stir until smooth, and hold at room temperature.
• Place the egg yolks and 3/4 cup sugar in the bowl of an electric mixer fitted with a paddle. Beat on high until slightly thickened and lemon-colored, about 4 minutes. Scrape down the sides of the bowl and beat on high for an additional 2 minutes.
• While the egg yolks are beating, whisk 4 egg whites in a large stainless steel bowl until stiff but not dry, about 3 to 4 minutes. Using a rubber spatula, fold the melted chocolate mixture into the beaten egg yolk mixture. Add a quarter of the beaten egg whites and stir to incorporate, then gently fold in the remaining egg whites. Divide the batter between the prepared pans, spreading evenly, and bake in the preheated oven until a toothpick inserted in the center comes out clean, about 25 to 30 minutes. Remove the cakes from the oven and allow to cool in the pans for 15 minutes. (During baking, the surface of the cakes will form a crust; this crust will normally collapse when the cakes are removed from the oven.) Invert 1 of the cakes onto the bottom of a springform pan. Invert the other 2 cakes onto cake circles. Remove the parchment paper and refrigerate cakes for 30 minutes.
• To prepare the chocolate and strawberry mousse, reserve the 12 best-looking strawberries to decorate the top of the cake. In a food processor fitted with a metal blade, puree 4 ounces of strawberries (12 medium-sized berries should yield 1/2 cup of puree). Set aside until needed. Refrigerate the remaining berries until needed (that includes the 12 berries for decoration) Heat 1-inch of water in the bottom half of a double boiler over medium heat. Place 16 ounces semisweet chocolate, the white chocolate and the strawberry puree in the top half of the double boiler. Tightly cover the top with film wrap. Allow to heat for 12 to 14 minutes. Remove from the heat and stir until smooth. Transfer to a stainless steel bowl, using a rubber spatula to remove all of the melted chocolate mixture. Keep at room temperature until needed. In the bowl of an electric mixer fitted with a balloon whip, whisk the 6 egg whites on high until soft peaks form, about 2 minutes. Continue to whisk on high while gradually adding 2 tablespoons sugar. Whisk until stiff but not dry, about 30 seconds. Set aside at room temperature until needed.
• Using a hand-held whisk, whip the heavy cream in a well-chilled stainless steel bowl until stiff. Fold a quarter of the egg whites into the melted chocolate mixture, then fold in the whipped cream. Now fold in the remaining egg whites. Set aside at room temperature until needed.
• Assemble the springform pan. Spread 1/2 cup of chocolate strawberry mousse onto the cake layer in the assembled springform pan. Arrange 1/2 the amount of reserved strawberries (not including the 12 for decoration), stem side down, into the mousse. The berries should be arranged in 2 rings: the first ring being 3/4-inch from the outside edge of the cake, and the second, inside ring, 3/4-inch away from the first. Distribute 3 cups of mousse over the berries, being careful to keep the berries in position. Holding the pan by the top rim, gently but firmly tap the bottom of the pan 2 to 3 times on your work surface (this will eliminate air pockets). Position a cake layer on top of the mousse, then repeat the process used on the first cake layer (1/2 cup mousse, remaining strawberries, and 3 more cups mousse). Top the mousse with the remaining cake layer and gently press into position. Refrigerate the cake for 2 hours (do not freeze).
• Refrigerate 1 cup of Semisweet Chocolate Ganache for at least 1 hour. Keep the remaining ganache at room temperature until needed.
• Remove the sides from the springform pan (do not remove the bottom of the pan from the cake; this will make it easier to handle later). Use a cake spatula to smooth and fill in the sides of the cake with 2 to 3 tablespoons of room-temperature ganache. Evenly spread the remaining amount of this ganache over the top and sides of the cake. Refrigerate the cake for 1 hour.
• Transfer the chilled cup of ganache to a pastry bag fitted with a large-sized star tip. Remove the cake from the refrigerator. Pipe a circle of 12 evenly spaced stars along the outside edge of the top of the cake. Place a strawberry, stem side down, into each ganache star. Refrigerate the cake for 30 minutes.
• Cut the cake with a serrated slicer, heating the blade of the slicer under hot running water before making each slice. Allow the slices to come to room temperature for 20 to 30 minutes before serving.
• Heat the heavy cream, butter, and sugar in a 2 1/2-quart saucepan over medium-high heat. When hot, stir to dissolve the sugar. Bring the mixture to a boil. Place the chocolate in a stainless steel bowl. Pour the boiling cream over the chocolate and allow to stand for 5 minutes. Stir until smooth. Allow to cool to room temperature.
• Yield: 2 cups

Steps:

• Preheat the oven to 350°F (180°C). Line the bottom of a 9-inch (23-cm) springform pan with parchment paper.
• Break up or chop the chocolate and place it in a heatproof bowl with the butter or margarine. Set the bowl over a saucepan of barely simmering water and allow the chocolate and butter to melt, stirring occasionally. When everything has melted, remove from the heat and let cool to room temperature.
• In the meantime, put the egg yolks in a large bowl. In the bowl of a stand mixer fitted with the whisk attachment, or in a large bowl, using a handheld mixer, whip the egg whites to very firm peaks, about 5 minutes.
• When the melted chocolate mixture has cooled, add it to the egg yolks, along with the sugar, and whisk well.
• Using a rubber spatula, stir about one-third or less of the egg whites into the chocolate mixture to lighten it. Carefully spoon another third of the egg whites on top of the chocolate mixture and gently fold them in. Add the remaining whites and fold them in just until incorporated.
• Transfer half of the batter to another bowl and set aside in the refrigerator.
• Pour the remaining batter into the prepared pan and bake for 20 minutes: it will turn into a soft, moist cake. Remove from the oven and let cool completely in the pan.
• When the cake has reached room temperature, pour the reserved chocolate mousse on top of it. Refrigerate the mousse cake, uncovered, for at least 2 hours, or overnight, until set.
• When you're ready to serve, run a sharp thin-bladed knife around the cake's edges and then remove the sides of the springform pan. Peel the paper from the bottom, and place the cake on a serving platter. Serve cold, decorated with chocolate shavings, if desired.
• Leftover cake will keep in the refrigerator, wrapped in aluminum foil, for a couple of days.

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Prepare and bake cake mix according to package directions for two 9-inch layers. Cool and remove from pans.
• In a large bowl, mix together sweetened condensed milk and melted chocolate. Gradually stir in the water, then instant pudding until smooth. Chill for at least 30 minutes.
• Remove the chocolate mixture from the refrigerator, and stir to loosen. Fold in whipped cream and return to the refrigerator for at least another hour.
• Place one layer of cake onto a serving plate. Top with 1 1/2 cups of the mousse, then cover with the remaining cake layer. Frost with the remaining mousse, and refrigerate until serving. Garnish with fresh fruit or chocolate shavings.

Steps:

• Heat oven to 375ºF.
• Pour chocolate syrup into 12-cup fluted tube pan sprayed with cooking spray.
• Beat cake mix, water, oil and 3 eggs in large bowl with mixer 2 min. or until blended. Add sour cream; mix well. Pour over syrup in pan.
• Beat cream cheese and sugar in separate bowl with mixer until blended. Add remaining eggs; mix well. Blend in evaporated milk and melted chocolate; gently spoon over cake batter in pan. Cover with Reynolds Wrap® Aluminum Foil sprayed with cooking spray, sprayed side down.
• Place tube pan in large shallow pan. Add enough water to larger pan to come at least 2 inches up side of tube pan. Bake 1 hour 30 min. or until toothpick inserted near center comes out clean. Cool cake completely in pan. Refrigerate 2 hours. Invert cake onto plate; remove pan. Serve cake topped with COOL WHIP.

Steps:

• For the base, melt the chocolate with the butter and golden syrup in a bowl over barely simmer watering or on a low heat in the microwave.
• Put the biscuits in a bag and crush with a rolling pin until they reach a crumb consistency. Combine the two and spread over the base of a 23cm springform tin. Refrigerate for about an hour to set.
• For the mousse, melt the remaining plain chocolate and the milk chocolate together in the same way and allow to cool until lukewarm. Using an electric beater, whisk the eggs whites in one bowl to stiff peaks. Softly whip the whipping cream in another bowl until thickened but not as far as soft peaks.
• Stir the egg yolks into the chocolate, then beat the cream into the mixture - a balloon whisk is good for this. Work quickly if the chocolate looks like it might be becoming grainy. Gently fold in the eggs whites with a whisk, spread the mixture over the biscuit base and return to the fridge overnight.
• Release from the tin and decorate with concentric circles of raspberries and serve.

Steps:

• Cake:.
• In a large bowl, combine the cocoa powder, espresso powder, and chocolate.
• Pour in the boiling water and stir until the chocolate is melted and the mixture is smooth.
• Stir in the vanilla and let cool; then stir in the buttermilk.
• In another bowl, using an electric mixer set at medium speed, beat the butter and oil together until light and fluffy.
• Add the sugars and beat until creamy.
• Beat in the eggs, one at a time, beating well after each addition.
• Sift together the flour, baking soda, and salt onto a sheet of waxed paper.
• Add one-third of the flour mixture and beat at low just until combined.
• Beat in half of the chocolate-buttermilk mixture just until combined.
• Scrape down the sides of the bowl with a rubber spatula.
• Beat in another one-third of the remaining flour mixture for no more than a few seconds, just until combined.
• Add the remaining chocolate-buttermilk mixture, beating just a few seconds.
• Finally, fold in the remaining one-third of the flour mixture by hand, using a large rubber spatula, just until no streaks of flour remain.
• Divide the batter between two 9-inch round cake pans that have been greased and lined with parchment.
• Bake at 350°F 25-30 minutes, or until a wooden skewer inserted in the center comes out clean.
• Transfer to wire racks and let cool 5-10 minutes.
• Invert the cakes onto the racks and peel the parchment paper from the layers.
• Let cool completely before frosting.
• Halve each cake layer horizontally using a long serrated knife (plain dental floss works for me) for a total of four thin cake layers.
• Place one layer cut-side up on a serving plate and top with 1 cup of the mousse buttercream, spreading it evenly.
• Continue stacking the cake, spreading 1 cup of the buttercream in between each layer and placing the layer cut-side down.
• Frost the top and sides of the cake with the remaining buttercream.
• Chocolate Mousse Buttercream:.
• Whisk together the eggs, sugar, and cocoa powder in the metal bowl of a stand mixer.
• Fill a large saute pan or skillet with water and bring to a simmer over mediium-high heat.
• Place the mixing bowl in the simmering water and whisk the egg mixture constantly until the sugar is completely dissolved and the mixture is thick, fluffy, and very hot, 3-4 minutes.
• Use an instant-read thermometer to check the temperature of the mixture -- it should be anywhere between 120-140°F.
• Remove the bowl from the simmering water and, using the whisk attachment, beat the eggs at medium-high speed until they are tripled in volume and form soft peaks and the bottom of the bowl is completely cool to the touch, about 10 minutes (it took 45 minutes with a hand mixer -- don't try it!).
• Beat in the vanilla and salt.
• While the eggs are mixing, unwrap the individual sticks of butter and rewrap them loosely in plastic wrap.
• Pound the butter 5-6 times with a rolling pin, until it is soft and malleable but still cool.
• With the mixer speed still on med-high, add the butter 2 T at a time, to the egg mixture, beating in each addition until it is incorporated.
• Don't panic if it seems liquidy or looks curdled; it will magically emulsify.
• When the buttercream is smooth and glossy with a subtle brown tint from the cocoa powder, turn off the mixer and carefully fold in the melted chocolate.

Steps:

• For the Cake:.
• Preheat oven to 425°F.
• Wrap the outside of an 8-inch spring form pan with a double layer of tin foil to prevent seepage.
• Butter the inside of the pan and cut a circle out of parchment paper the size of the bottom of the pan. Place it in and butter it too.
• Combine the chocolate and butter in a double boiler over simmering water (don't let it touch the bottom of the pot, it will scorch the chocolate). Stir until the chocolate and butter are smooth and lump free. You can also microwave the mixture on 100% or high. Make sure you stop and stir the mixture every 15 seconds; remove the chocolate when all the lumps are gone.
• Put the eggs in a large mixer bowl over simmering water and stir constantly until warm to the touch, about 3 minutes; remove from the heat. If using an electric mixer, beat the eggs until triple in volume and form soft peaks when the beater is lifted, 5-8 minutes. To ensure maximum volume when using a hand mixer continue to beat the eggs over simmering water until hot to the touch, about 5 minutes, then removed from heat until cool.
• Fold half the eggs into the melted chocolate until partially incorporated. Add the remaining eggs and fold until just blended but no streaks remain.
• Pour at once into your prepared spring form pan and smooth the surface with an off-set spatula. Place the spring form pan into a larger pan and carefully pour boiling water into the larger pan until the water is about 2/3 of the way up the side of the spring form pan. Don't get any water on the chocolate! This method of a water bath is often referred to as a "bain marie".
• Bake the cake for 5 minutes. Then cover the spring form pan loosely with lightly buttered tin foil and bake for 10 more minutes. Remove the cake from the oven and let cool on a wire rack for 45 minutes; then cover it again and refrigerate it for at least 3 hours.
• To remove the cake from the spring form pan: Run a small spatula around the edge of the spring form until the sides of the cake come loose. Place the cake on a round plate that the cake fits nicely on and invert the plate and open the spring form pan up and remove from the cake. Remove the bottom metal part of the spring form pan and the parchment. Cover it again with tin foil and leave for another 6 hours or over night. It needs to be really chilled to set.
• If you are making the Ganache, set the cake on a metal rack and put wax paper under the cake (tuck strips). Pour the tepid glaze over the center of the cake and allow the ganache to dribble down the sides of the cake.
• Using a metal off set spatula run it around the top of the cake to ensure that the g.
• Ganache won't be too thick on the top. Patch any bare spots at this point. If any air holes occur, use a pin to break them. Remove the strips of wax paper from under the cake and let this stand undisturbed for 2-3 hours at room temperature, or 30 minutes in the fridge.

• heat oven to 160C/fan 140/gas 3. Line and butter a 23cm springform tin. Put chocolate and butter in a pan and melt over a very low heat. Set aside. Using an electric whisk, beat the eggs with the sugar for about 5mins untill the mixture is thick, pale and doubled in volume.
• Pour the chocolate into the whisked egg mixture, then gently, but thoroughly, fold in. Add the broken biscuits, then gently fold again.
• Pour the mixture into the prepared tin, then bake for 40-45mins until just firm. Remove from the oven and allow to cool in the tin for about 1/2-3/4 hr. You can serve it while still warm and the centre is still melty and gooey, as in the picture, or you can chill it (up to a day ahead) and it will be firm and fudgy enough to cut into wedges. Serve with double cream and fresh blueberries or homemade ice cream.
