Mary Berry Chocolate Mousse Cake Recipes

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:

• Preheat the oven to 350 degrees F. Butter two 8-inch round cake pans, line the bottoms with parchment paper, butter the parchment and dust with flour, tapping out excess.
• Whisk the flour, sugar, cocoa powder, baking soda, baking powder and salt together in a large bowl. Whisk the melted butter, buttermilk, egg, vanilla and 1/2 cup water together in another bowl until smooth. Add the wet ingredients to the dry ingredients, whisking until just combined. Divide the batter between the prepared cake pans, smoothing the tops. Bake, rotating the pans halfway through cooking, until a toothpick inserted in the center of each cake comes out clean, about 25 minutes.
• Transfer the cakes to a rack and let cool 15 minutes. Invert the cakes on the rack, discard the parchment paper then flip the cakes right-side-up again. Move the rack with the cakes over a baking sheet and let the cakes cool completely.
• Make the raspberry mousse: In a small saucepan, mash the raspberries with the sugar and salt and bring to a simmer over medium heat. Cook, stirring often, until thickened and jammy, 6 to 8 minutes. Remove the pan from the heat, press the raspberry mixture through a sieve into the bowl of a food processor and let cool completely.
• Combine the gelatin with 1 tablespoon cold water in a small bowl and let stand for 5 minutes to soften. Heat the gelatin in the microwave until it melts completely, about 10 seconds, stirring to dissolve. Add the gelatin mixture, cream cheese and sour cream to the food processor and process until smooth. Scrape the mixture into a bowl and refrigerate, checking every 5 minutes, until the mousse is just set enough to spread, 5 to 15 minutes. (Do not let the mousse firm up too much.)
• Place one cake layer on a cake stand and pile the raspberry mousse in the center, spreading it in a thick layer almost to the edge. Top with the remaining cake, aligning the layers directly on top of each other so the cake does not lean. Refrigerate the assembled cake for 1 hour.
• Meanwhile, make the chocolate ganache: Bring the cream to a simmer in a small saucepan then remove from heat. Add the chocolate, shaking the pan gently to submerge it. Allow the pan to stand, off the heat, for 3 minutes to melt the chocolate. Whisk the ganache smooth, then refrigerate until it is just thick enough to spread (like mayonnaise), about 5 minutes. (Do not let the ganache harden too much.)
• Stir the ganache again and scoop it on top of the cake, spreading it over the top and sides. Refrigerate the cake until the ganache is set, at least 2 hours or overnight.

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.
