The Ultimate Chocolate Mousse Cake Recipes

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.
• Bon Appetit!

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.
