Steps:

• Make the chocolate mousse: Put the chocolate in a food processor fitted with the metal chopping blade.
• Process for 20 to 30 seconds, until finely ground.
• In a small saucepan, combine the milk, sugar and salt.
• Cook over medium heat, stirring with a wooden spoon, until the sugar dissolves and the milk comes to a boil.
• Remove the pan from the heat.
• With the motor of the food processor running, pour the hot milk through the feed tube.
• Process for 10 to 20 seconds, until the chocolate is completely melted.
• Using a spatula, scrape down the side of the work bowl.
• Add the oil and vanilla extract; process for 5 to 10 seconds, until the mixture is creamy.
• Scrape the chocolate mixture into a large bowl and cool for about 5 minutes, until tepid.
• In a chilled 4-1/2 quart bowl of a heavy-duty electric mixer fitted with the wire whisk attachment, whip the cream until soft mounds barely start to form and the cream is still pourable.
• Do not overwhip the cream.
• Using a large rubber spatula, gently fold one-third of the whipped cream into the tepid chocolate mixture to lighten it.
• Fold in the remaining whipped cream.
• Do not overfold the mousse or the texture will be grainy.
• Cover with plastic wrap and chill for 6 to 8 hours or overnight, until firm.
• Make the cake: Grease three 10-inch round cake pans.
• Cut three 10-inch circles of waxed paer and place in the bottom of each pan.
• Grease the pan well and then flour, tapping out the excess.
• Set aside.
• Place the oven racks two shelves apart.
• Preheat the over to 350 degrees F.
• Sift together the flour, baking soda and salt.
• Set aside.
• Place the coarsely chopped chocolate and the water on top of a double boiler and turn heat to medium-high, whisking occasionally until smooth.
• Remove from the top of the double boiler and cool slightly.
• Meanwhile, in a 4-1/2 quart bowl of a heavy-duty electric mixer using the paddle attachment, cream together the butter and the sugars.
• Add the vanilla.
• Add the eggs one by one, mixing on medium speed until blended.
• Using a rubber spatula, scrape down the sides of the bowl.
• With the mixer at its lowest speed, add half of the dry ingredients and the half of the buttermilk.
• When blended, add the remaining buttermilk and the chocolate mixture.
• Mix until blended then add the remaining dry ingredients.
• Mix on medium speed just until blended and the flour lumps disappear.
• Divide evenly among the three prepared pans and smooth the tops with an offset metal spatula.
• Bake for 28 to 32 minutes, or until a toothpick comes out clean.
• Remove the pans from the oven and place on wire cooling racks.
• Cool for 15 minutes and invert.
• Peel off the waxed paper and cool completely.
• Begin to assemble the cake: Place a dab of chocolate mousse and then a layer of the cooled cake on a 10-inch cardboard cake circle or the circular insert of a tart pan.
• Using a large rubber spatula, place about one-quarter of the chilled chocolate mousse on top of the first cake layer.
• Using a metal cake spatula, spread the mousse evenly not quite to the sides of the cake.
• There should be slightly less than one-half inch of mousse on top of the cake.
• Place the second cake layer on top and repeat the mousse layer.
• Place the third cake layer on top, then spread the remaining chocolate mousse over the top and sides of the cake, coating smoothly and evenly.
• Place the cake in the freezer for a minimum of four hours.
• Make the ganache glaze: Place the coarsely chopped chocolate in a food processor fitted with the metal chopping blade.
• Process for 20 to 30 seconds, until finely ground.
• Place in a large bowl.
• In a medium pan, scald the heavy cream and pour over the chocolate.
• Using a metal whisk, gently stir until smooth and melted.
• Continue stirring until the ganache is room temperature or just slightly warmer.
• Glaze and garnish the cake: Place the Oreos in a food processor fitted with the metal chopping blade.
• Process for 20 to 30 seconds, until finely ground.
• Remove the cake from the freezer and place on a wire rack that has been set over aluminum foil or a sheet pan.
• Slowly pour the ganache over the top of the cake, smoothing with a large metal cake spatula.
• When the top has been coated, slowly pour the ganache around the sides of the cake so it drips down and coats the sides.
• Use the spatula to spread the ganache evenly over the sides of the cake.
• When completely coated with the ganache, scoop the Oreo crumbs with your hand and press them onto the sides of the cake, coating its entirety.
• Refrigerate until ready to serve.

Steps:

• ----makethe chocolate genoise----:[You can also use your favorite Chocolate American Butter Cake if you don't feel comfortable with the genoise] preheat the oven to 350 degrees F.
• butter a 9" springform pan, put a round of parchment in the bottom, butter again and flour.
• Sift the cocoa and flour into a medium bowl, whisk to combine, set aside.
• Fill a pot one third full with water and bring to a simmer.
• Comine the eggs and sugar in the bowl of an electric mixer.
• Place the bowl over the simmering water (bowl should not be touching the water) and whisk until the mixture is warm to the touch.
• Transfer the bowl to the mixer and, using the whisk attachment, beat on medium speed until the mixture triples in volume and forms a thick ribbon when the whisk is lifted-- about 8 minutes.
• In four batches, sift the flour mixture into the egg mixture and quickly, but gently, fold the flour in.
• (this may take some practice).
• Fold in the butter, scrape into prepared pan.
• Bake cake for 20-25 minutes, until it's just pulled away from the sides and the top springs back when lightly touched.
• Cool in the pan for 10 minutes then unmold cake on a cooling rack and allow to sit until room temperature.
• Leave the cake on the bottom of the springform pan.
• ----Make the Sugar Syrup----: Combine the 1/4 cup of sugar with 1/4 cup of water in a small sauce pan.
• You can flavor the syrup with a liquer if desired.
• Almond or hazlenut works well with this cake.
• Bring to a boil (be sure to cook off all alcohol if using a liquer).
• Let cool to room temperature.
• ----Makethe Mousses----: Chop the chocolate and place in three medium bowls.
• Bring the cream to a boil in a small sauce pan.
• Pour a half cup of hot cream into each of the bowls of chocolate.
• Whisk each until smooth (it's nice to have a helper for this;-).
• Let the chocolate mixtures cool for 15 minutes, should be a warm room temperature.
• Meanwhile whip the 3 3/4 cups of cream and refrigerate.
• When all is cool gently fold 1/3rd of the cream into each of the chocolates, refrigerate.
• ----Assemblethe cake----: Using a long serrated knife cut the cake horizontally into three layers.
• Install side of springform pan.
• Brush sugar syrup onto the bottom layer, spread the milk chocolte mousse onto the cake.
• Place 2nd cake layer ontop of the mousse and brush with syrup.
• Spread white chocolate on this layer.
• Finally, put the top on the cake and spread dark chocolate mousse.
• Cover and refrigerate for a minimum of four hours or up to 24 hours.
• Garnish with white chocolate curls before serving.
• I've kept this cake for a couple days with good results, but it is at it's peak the same day it's made.

Steps:

• Line three 9-inch cake pans with foil, leaving about a 2-inch overhang on all sides. (See Cook's Note.)
• Add the cookies and sugar to the bowl of a food processor and pulse to fine crumbs. Drizzle in the butter and pulse until the crumbs are completely coated and moistened with the butter. Firmly press the crumb mixture into the bottom of one of the prepared pans; set aside.
• Add the dark chocolate pudding mix to a large bowl and whisk in 2 cups of the heavy cream. Continue whisking until light and fluffy, about 2 minutes. (It's fine if there are still a few granules in the mix; they will dissolve once set.) Pour the pudding mixture on top of the crumb crust and spread until even. Freeze until firm, about 2 hours.
• Meanwhile, clean out the bowl, add the chocolate pudding mix and whisk in 2 cups heavy cream. Continue whisking until light and fluffy, about 2 minutes. Pour into another prepared pan and freeze until firm, about 2 hours.
• Clean out the bowl again, then add the white chocolate pudding mix and whisk in the remaining 2 cups heavy cream. Continue whisking until light and fluffy, about 2 minutes. Pour into the third prepared pan and freeze until firm, about 2 hours.
• When all 3 layers are completely frozen, use the foil to lift out the cakes from the pans. Place the dark chocolate layer crumb-side down on a cake stand or large plate. Top with the chocolate layer and then with the white chocolate layer. Refrigerate until the layers are thawed and the cake is set, about 8 hours and up to overnight.
• Before serving, run a hot knife around the outside of the cake to smooth it and sprinkle the top with the chocolate shavings.

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:

• 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:

• 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:

• For a 1.2 litre terrine, cut a strip of greaseproof paper as long as the tin and wide enough to cover the bottom and come up both long sides, with about 7.5cm to spare. Put the paper in the tin as if to line it, then draw a line across the paper on both sides where it meets the bottom edge, and the top edge, of the tin. Take the paper out of the tin and draw two lines at equal intervals between the bottom and top edge lines you have already drawn. (This will help you make each layer exactly the same depth when filling the tin.) Lightly grease the paper and use to line the tin.
• Whip a third of the cream to just soft peak stage, then chill. Melt the milk chocolate in a heatproof bowl set over a pan of simmering water or microwave on High for 2 mins. Whisk 2 egg yolks and 25g/1oz sugar in a heatproof bowl over a pan of simmering water with a hand-held electric blender for about 2-3 mins until the mixture has at least doubled in volume. Once you have reached this stage, remove the bowl from the heat and keep whisking, adding the melted chocolate - this not only incorporates the chocolate, but also cools the mixture more quickly. Leave to cool for a few minutes, then carefully fold in the whipped cream.
• Quickly whisk two egg whites into soft peaks, making sure the bowl and whisk are spotless to ensure the maximum volume is obtained. Using a large metal spoon, carefully fold the egg white into the chocolate mixture so you don't knock out too much air.
• Pour mixture into the terrine, filling it to first mark (any extra can be frozen), then freeze for 20-30 mins before starting the white chocolate mixture. Repeat process with white chocolate, then the plain; cover with plastic film and freeze completely. To guarantee a good set, make terrine at least 8-10 hrs or up to 2 days before.
• Dip the tin briefly in a large bowl of hot water. Put a chopping board or flat plate on top and invert the mousse. Gently remove the paper and open freeze for about 10 mins to re-set. To decorate, pipe an outline of melted plain chocolate in a teardrop shape onto each plate. Dust the plates lightly with icing sugar, then carefully fill the teardrop with cream. Slice the mousse, wiping the knife after each cut, and put a slice on each plate. Decorate with chocolate curls and serve at once.

Steps:

• Butter 2 8" cake pans or muffin pans, etc, and coat evenly with cocoa powder (I began using my new silicone pans with this recipe and did not need to pre-treat my pans with butter or cocoa).
• In large bowl mix together well first 8 ingredients with a wire whisk.
• Add eggs, chocolate milk, hot fudge topping, butter and vanilla; beat on medium for 2 minutes.
• In a small bowl, mix together hot water and instant espresso, stirring well to dissolve.
• Add espresso carefully to cake mix and beat until mixed well, batter will seem thin.
• Pour evenly into the prepared pans.
• Bake in pre-heated oven at 350º for about 40 minutes or until toothpick comes out clean; it's a dense cake and won't rise as high as you might expect.
• Cool in pans 10 minutes, then turn out onto wire racks to cool completely.
• Frost or dust with powdered sugar as desired.

Steps:

• Line 8-inch square pan with foil, with ends of foil extending over sides. Process cookies in food processor until finely ground; mix with butter. Press onto bottom of prepared pan.
• Place 3 oz. semi-sweet chocolate in medium microwaveable bowl; add 2 Tbsp. milk. Microwave on HIGH 30 sec.; stir until chocolate is completely melted and mixture is well blended. Repeat with 2 oz. white chocolate and 2 Tbsp. milk in separate microwaveable bowl. Then, repeat with remaining semi-sweet chocolate, remaining white chocolate and 2 Tbsp. of the remaining milk in third microwaveable bowl. Cool.
• Beat pudding mix and remaining milk in medium bowl with whisk 2 min. Stir 1/3 cup pudding mixture and 2 tsp. cocoa powder into melted semi-sweet chocolate. Stir 1/3 cup of the remaining pudding mixture into each of the remaining 2 bowls of melted chocolate until blended. Gently stir 1 cup COOL WHIP into chocolate mixture in each bowl.
• Layer pudding mixtures over crust, starting with semi-sweet/cocoa mixture and ending with white chocolate mixture, smoothing top of each layer before adding the next. Refrigerate 4 hours or until firm.
• Use foil handles to remove dessert from pan just before serving. Sprinkle lightly with remaining cocoa powder. Cut into 9 squares, then cut each square diagonally in half.

Steps:

• SOFT MOUSSE: Melt chocolate over simmering water of a water bath.
• Whip egg yolks with 1/3 cup powdered sugar until pale and airy, place whipped yolks in medium sized bowl. Add warm melted chocolate and fold until just mixed. Wash bowl and wipe thoroughly.
• Dissolve 1/3 cup granulated sugar and 1/4 cup water in small pot, bring to a boil, cook to 230 degrees on a candy thermometer.
• While sugar is boiling slowly whip whites to soft peak. When sugar is ready, slowly pour into whites while beating at a medium speed in a steady stream. Continue to whip until stiff peaks form. Spoon whites on top of yolks but do not fold.
• Whip cream and 1/3 cup powdered sugar until medium stiff peak, now fold in whites until just mixed. Add cream and fold until incorporated. Do not over fold. Store in refrigerator until ready to use (should be used as soon as possible).
• SOLID CHOCOLATE MOUSSE: Melt chocolate hot, over double broiler (do not burn chocolate), heat until it is warm to the touch. Whip cream until very soft peaks form (lines show in slightly whipped cream).
• Very, very quickly add chocolate to cream and fold in, mixture may look broken but keep folding until everything is smooth, but do not overmix. Place in bowl, cover and refrigerate until set.
• TO SERVE: Place the two mousses in composition to contrast each other. Garnish with chocolate cool whip.

Steps:

• Make the cake:.
• Adjust the oven rack to the middle of the oven and heat to 350ºF. Lightly grease and flour 1 8-inch springform pan. Tap out any excess flour.
• Place the chocolate in a small heatproof bowl. Bring water to a boil and pour it over the chocolate. Stir with a silicone spatula until the chocolate is melted and smooth, about 2 minutes. Add the coffee granules and cocoa powder. Whisk until smooth. Add 1/4 cup of the sugar and stir until thick and glossy, about 2 minutes.
• In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and remaining sugar together until light and fluffy. Beat in the eggs and egg yolks, one at a time, mixing well after each addition. Beat in the vanilla. Add the chocolate mixture and mix until thoroughly combined.
• In a small bowl, combine the flour, baking soda, and salt. Stir with a whisk. Add half of the flour mixture to the chocolate mixture, followed by the buttermilk, mixing until incorporated. Add remaining flour mixture and mix until the batter is thoroughly combined.
• Spread the batter into the bottom of the prepared pan, smoothing it to the edges with a spatula. Bake for 25 to 30 minutes or until a toothpick inserted into the center comes out clean. Cool to room temperature in the pan on a wire rack.
• Make the mousse:.
• In a small bowl, sprinkle the gelatin over water, let stand for 5 minutes. Place chocolate and sugar in a medium bowl. Bring 1/2 cup of the cream to a simmer in a small saucepan over medium-high heat. Remove from heat; add the softened gelatin and stir until fully dissolved. Pour the cream over the chocolate and whisk until chocolate is melted and mixture is smooth. Cool to room temperature, stirring occasionally. The mixture will thicken slightly.
• In the bowl a stand mixer fitted with the whisk attachment, whip the remaining 1 cup cream at medium speed until it begins to thicken, about 30 seconds. Increase the speed to high and whip until soft peaks form, about 30 to 60 seconds. Use a whisk to mix in 1/3 of the whipped cream into the chocolate mixture. Use a rubber spatula to fold the remaining whipped cream into the chocolate mixture until no streaks appear. Spoon the chocolate mousse into the pan over the chocolate cake. Smooth the top with an offset spatula. Return the cake to the refrigerator and chill until set, about 2 hours.
• Make the ganache:.
• Heat the cream and butter in a medium saucepan over medium-high heat. Remove from heat just before it begins to boil. Place the chocolate in a medium heatproof bowl and pour the hot cream over the chocolate. Stir until chocolate is melted and smooth. Cool to room temperature. Spread the ganache over the top of the mousse layer and refrigerate until set. About 45 minutes.
• Run a knife along the outer edge of the cake to loosen it from the pan and gently remove from the pan. Serve with whipped cream or fresh berries.
• Notes.
• Total time does not reflect the time needed for the mousse and ganache to set. Please allow 3 extra hours for this.
