Chocolate Ganache 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:

• Preheat the oven to 325 degrees. Butter and flour an 8-inch round cake pan, then line the bottom with parchment paper.
• Cream the butter and sugar in the bowl of an electric mixer fitted with the paddle attachment until light and fluffy. Add the eggs, one at a time. Mix in the chocolate syrup and vanilla. Add the flour and mix until just combined. Don't overbeat, or the cake will be tough.
• Pour the batter into the pan and bake for 40 to 45 minutes, or until just set in the middle. Don't overbake! Let cool thoroughly in the pan.
• For the ganache, cook the heavy cream, chocolate chips, and instant coffee in the top of a double boiler over simmering water until smooth and warm, stirring occasionally.
• Place the cake upside down on a wire rack and pour the glaze evenly over the top, making sure to cover the entire cake and sides. You can tilt the rack to smooth the glaze. Decorate with candied violets, if desired, or gently crumble the gold leaf and place it on the center of the cake. Do not refrigerate.

Steps:

• Place the chocolate into a medium bowl. Heat the cream in a small sauce pan over medium heat. Bring just to a boil, watching very carefully because if it boils for a few seconds, it will boil out of the pot. When the cream has come to a boil, pour over the chopped chocolate, and whisk until smooth. Stir in the rum if desired.
• Allow the ganache to cool slightly before pouring over a cake. Start at the center of the cake and work outward. For a fluffy frosting or chocolate filling, allow it to cool until thick, then whip with a whisk until light and fluffy.

Steps:

• Preheat oven to 350°. Line bottoms of 3 greased 9-in. round baking pans with parchment; grease paper. In a large bowl, whisk flour, sugar, cocoa and baking soda. Beat in mayonnaise, coffee and vanilla. Transfer batter to prepared pans. Bake 30-35 minutes or until a toothpick inserted in center comes out clean. Cool in pans 10 minutes before removing to wire racks; remove paper. Cool completely., For filling, in a small heavy saucepan, mix sugar and cornstarch. Whisk in milk. Cook and stir over medium heat until thickened and bubbly. Reduce heat to low; cook and stir 2 minutes longer. Remove from heat; stir in vanilla. Cool completely. In a large bowl, cream butter. Gradually beat in cooled mixture. Stir in chocolate chips., For ganache, place chocolate in a large bowl. In a small saucepan, bring cream just to a boil. Pour over chocolate; let stand 5 minutes. Stir with a whisk until smooth. Stir in vanilla. Cool to room temperature, stirring occasionally. Refrigerate, covered, until cold. Beat ganache just until soft peaks form, 15-30 seconds (do not overbeat)., Place 1 cake layer on a serving plate; spread with half of the filling. Repeat layers. Top with remaining cake layer. Frost top and sides of cake with ganache. In a microwave-safe bowl, combine chocolate, cream and butter. Microwave at 50% power for 1-2 minutes or until smooth, stirring twice. Cool slightly, stirring occasionally. Drizzle over cake, allowing some to flow over sides. Refrigerate at least 2 hours before serving.

Steps:

• Place the chocolate in a medium heatproof bowl. Place the cream in a small saucepan, and bring to a boil. Pour over the chocolate, and let sit for 5 minutes. Whisk until completely smooth. Allow to cool, stirring occasionally, until lukewarm. Use immediately.

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:

• Heat oven to 375°F In medium bowl, stir together cookie crumbs and melted butter. Press into bottom of 9-inch springform pan. Bake 10 minutes or until set.
• Make the mousse: gently melt semisweet chocolate in a double boiler with the 2 tablespoons whipping cream. Cool. When cool enough that butter will not melt, beat in butter. Stir in rum. In large bowl beat egg yolks and sugar on high speed for 5 minutes or until very light; fold into chocolate mixture. In large bowl beat whipping cream until soft peaks form; fold into chocolate mixture. Spread over crust. Refrigerate.
• Place 6 oz. chocolate in large bowl. Heat 3/4 cup cream in small saucepan over medium heat or in microwave on high until cream comes to a boil. Immediately pour cream over chocolate; stir until smooth. Cool until slightly thickened but still pourable (about 75°F.). Spoon over mousse.Cover and refrigerate until set, at least 8 hours or overnight.
