Dark Chocolate Mousse Cake Recipes

DARK CHOCOLATE MOUSSE

Steps:

• Place chocolate in a large bowl set over a bain marie or in a double boiler at a low simmer. Stir chocolate until melted. Turn off the heat and let stand.
• Beat the cream over ice until it forms soft peaks. Set aside and hold at room temperature. With a mixer, whip egg to soft peaks. Gradually add the sugar and continue whipping until firm.
• Remove the chocolate from the bain marie and using a whisk, fold in the egg whites all at once. When the whites are almost completely incorporated, fold in the whipped cream. Cover the mousse and refrigerate for approximately 1 hour or until set. Serve in goblets topped with more whipped cream and shaved chocolate, if desired.

DARK CHOCOLATE MOCHA MOUSSE CAKE

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.

EASY DARK CHOCOLATE MOUSSE

Steps:

• Beat 3/4 cup sugar and egg yolks together in a bowl.
• Melt chocolate in a microwave-safe glass or ceramic bowl in 15-second intervals, stirring after each interval, 1 to 3 minutes. Add butter gradually and beat until smooth. Beat into the egg yolk mixture.
• Beat egg whites and salt together in another bowl until stiff peaks form. Sprinkle 1 tablespoon sugar over and beat for 2 minutes more. Stir egg whites slowly into chocolate bowl. Refrigerate for at least 6 hours; overnight is best.

INTENSE CHOCOLATE MOUSSE CAKE

Steps:

• Heat oven to 350 degrees. Position the oven rack in lower center of the oven. Cover the outside of a 9-inch springform pan with a double layer of foil. Using a microwave oven or double boiler, melt together chocolate and butter; set aside to cool slightly.
• In a bowl, whisk together egg yolks and 1/2 cup sugar until pale, frothy and increased in volume. Whisk in brandy, then fold in chocolate mixture. Place a kettle of water over heat, and bring it to a boil. Using an electric mixer, whisk egg whites and salt until thick. Add remaining 1/4 cup sugar, and continue to whisk until stiff and shiny but not dry.
• Fold about 1/2 cup whisked egg whites into the chocolate mixture to lighten it. Gently fold in remaining whites, being careful not to let the mixture deflate. Pour mixture into lightly-buttered springform pan, and place pan in a roasting pan. Add boiling water to roasting pan to come halfway up side of springform pan. Bake for 45 minutes; top of cake will be hard and inside will be gooey.
• Remove cake pan from water, and place on a rack to cool completely. Unwrap foil and remove side of springform pan. Place cake on a serving platter. Just before serving, dust top with confectioners' sugar passed through a sieve.

MILK-AND-DARK-CHOCOLATE MOUSSE CAKE

Steps:

• Make the chocolate génoise:
• 1. Preheat the oven to 350°F. Butter a 9-inch round cake pan. Dust the pan with flour and tap out the excess.
• 2. Whisk together the flour and cocoa powder in a medium bowl; set aside.
• 3. Fill a pot one-third full with water and bring to a simmer. Combine the eggs and sugar in the bowl of an electric mixer.

Using a large rubber spatula, gently fold in the flour mixture. Fold in the melted butter. Scrape the batter into the pan and smooth the top.
• 4. Bake the cake for 20 to 25 minutes, until it has pulled away from the side of the pan and the top springs back when lightly touched. Cool the cake in the pan for 10 minutes. Unmold the cake on a rack and cool completely, right side up.
• Make the milk and dark chocolate mousses:
• 5. In the bowl of an electric mixer, using the whisk attachment, beat 2 1/2 cups (580 grams) of the heavy cream to soft peaks. Scrape half of the whipped cream into a medium bowl. Cover both bowls and refrigerate.
• 6. Put the milk and dark chocolate in two separate medium bowls. Bring the remaining 1 cup (232 grams) cream to a boil in a small saucepan. Pour 1/2 cup (116 grams) of the hot cream over the milk chocolate and the remaining 1/2 cup (116 grams) over the bittersweet chocolate. Gently whisk the milk chocolate until it is completely melted and the mixture is smooth. Whisk the dark chocolate until smooth.
• 7. Let the chocolate mixtures cool for 10 minutes. Fold the milk chocolate mixture into one bowl of whipped cream. Fold the dark chocolate into the remaining whipped cream.
• Make the sugar syrup:
• 8. Combine 1/4 cup (59 grams) water and the sugar in a small saucepan. Bring to a boil over medium-high heat, stirring to dissolve the sugar. Let the syrup cool to room temperature.
• Assemble the cake:
• 9. Using a serrated knife, slice the cake horizontally in half. Cup a strip of parchment paper to line the inside of a 9x4-inch cake ring. Line the mold with the strip and place it on a serving plate. Place a 9-inch cardboard cake round in the bottom of the cake ring. Place the bottom cake round, cut side up, in the ring. Brush the cake generously with the sugar syrup. Scrape the dark chocolate mousse onto the cake and smooth it into an even layer. Top with the second cake round, cut side down. Brush the cake generously with syrup. Scrape the milk chocolate mousse onto it, smoothing it into an even layer. Chill the cake for at least 2 hours and up to 24 hours.
• 10. To unmold the cake, lift it off the plate, holding it with your palm against the cardboard round. Using a hairdryer or warm damp towel, briefly warm the cake ring mold. Lift off the ring mold and peel off the parchment strip. Allow the cake to stand at room temperature for 30 minutes before serving.

PASSOVER CHOCOLATE MOUSSE CAKE

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.
