Bittersweet Chocolate Mousse Cake Recipes

Steps:

• Create an ice bath in a large bowl using ice and a little cold water. Nestle a smaller bowl in ice bath.
• Place chocolate and 1 cup water in a small pot and heat over medium. Whisk until mixture is melted and smooth, about 3 to 5 minutes.
• Immediately pour melted chocolate into the bowl in the ice bath. Vigorously whisk chocolate mixture by hand until thick, 3 to 5 minutes. The chocolate should be fluffy and form a mound when dolloped with the whisk (it should generally have the texture and appearance of mousse). If the mixture does not thicken, add a bit more chopped chocolate and remelt over the heat. Spoon into serving bowls and garnish with fleur de sel.

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:

• Finely chop chocolate; reserve. In a double boiler, whisk yolks, sugar, and salt until sugar has dissolved and mixture is warm to the touch, 2 to 3 minutes. Off heat, quickly whisk in chopped chocolate until melted and cocoa until smooth (mixture will be thick). Cool to room temperature.
• In a medium bowl, whip cream until soft peaks form. Whisk half of whipped cream into room-temperature chocolate mixture. Gently fold in remaining whipped cream with a rubber spatula. Divide mousse among four serving dishes. Chill at least 2 hours and up to 1 day.
• Remove mousse from refrigerator 15 minutes before serving. Garnish with shaved chocolate.

Steps:

• Preheat the oven to 350 degrees F. Butter and flour an 8-inch springform pan.
• Place a large heatproof bowl over a pot of simmering water, making sure the water doesn't touch the bowl. Put the butter and chocolate in the bowl, stirring occasionally, until the chocolate melts. Take the bowl off the heat and set aside.
• First, whisk the sugar into the chocolate mixture, then whisk in the eggs, coffee, and salt, whisking until the mixture is combined and smooth. Sprinkle on the flour and fold it in with a rubber spatula until it's incorporated.
• Pour the batter into the prepared pan and place it on a sheet pan. Bake for 30 to 40 minutes (see Cook's Note), until the top puffs up and cracks and the cake doesn't wobble when you jiggle the pan. (A toothpick will not come out clean.) Remove from the oven and cool completely on a baking rack. The cake will deflate as it cools. Run a small knife around the cake and remove the sides of the pan. Cut the cake in wedges and serve warm or at room temperature with sweetened whipped cream, vanilla ice cream, or crème fraîche.

Steps:

• Whisk milk, egg yolks, and 2 tablespoons sugar in heavy small suacepan to blend. Place over medium-low heat and stir until mixture thickens enough to coat spoon, about 7 minutes (do not boil). Remove from heat. Immediately add chocolate and whisk until smooth. Whisk in vanilla. Transfer mixture to medium bowl; cool to lukewarm, stirring occasionally, about 10 minutes. Beat egg whites and salt in large bowl until soft peaks form. Gradually add remaining 2 tablespoons sugar, beating until stiff but not dry. Fold whites into cooled chocolate mixture in 3 additions. Divide mousse among 6 goblets or transfer to serving bowl. Refrigerate until cold and set, at least 6 hours. (Can be made 1 day ahead. Cover and keep refrigerated.)
• Top mousse with whipped cream and chocolate shavings, if desired.

Steps:

• Preheat oven to 325°F. Line bottom of 9-inch-diameter cake pan with 2-inch-high sides with waxed paper. Butter sides of pan and paper. Dust pan with flour. Melt chocolate and butter in top of double boiler over simmering water, stirring until smooth. Cool slightly.
• Whisk yolks and sugar in large bowl until pale yellow. Mix in flour, then chocolate mixture. Using electric mixer, beat whites in another bowl until stiff but not dry. Fold into chocolate mixture. Pour batter into prepared pan. Bake until toothpick inserted into center comes out with only a few moist crumbs attached, about 25 minutes. Cool completely in pan on rack. Run small sharp knife around sides of pan to loosen cake. Turn cake out onto platter and cool. (Can be prepared 8 hours ahead. Cover with cake dome and let stand at room temperature.) Sift powered sugar over cake and serve.

Steps:

• Adjust an oven rack to the lower-middle position and heat the oven to 325°. Butter the sides of a 9-inch spring-form pan; flour the sides and tap out the excess. Line the bottom of the pan with a parchment or waxed paper round. Wrap the bottom and sides of the pan with a large sheet of foil (the OUTSIDE of the pan).
• In a double boiler: Melt 12 tablespoons butter and the chocolates in a large bowl over a large saucepan containing about 2 quarts barely simmering water, stirring occasionally, until the chocolate mixture is smooth. Cool the mixture slightly, then whisk in the vanilla and egg yolks. Set the chocolate mixture aside, reserving the hot water, covered, in the saucepan.
• In the clean bowl of a standing mixer fitted with the whisk attachment, beat the egg whites and salt at medium speed until frothy, about 30 seconds; add half of the crumbled brown sugar, beat at high speed until combined, about 30 seconds, then add the remaining brown sugar and continue to beat at high speed until soft peaks form when the whisk is lifted, about 2 minutes longer. Using a whisk, stir about one third of the beaten egg whites into the chocolate mixture to lighten it, then fold in the remaining egg whites in 2 additions, using the whisk. Gently scrape the batter into the prepared spring-form pan, set the spring-form pan in a large roasting pan, then pour the hot water from the saucepan into the roasting pan to a depth of 1 inch. Carefully slide the roasting pan into the oven; bake until the cake has risen, is firm around the edges, the center has just set, and an instant-read thermometer inserted into the center registers about 170°, 45 to 55 minutes.
• Remove the spring-form pan from the water bath, discard the foil, and cool on a wire rack for 10 minutes. Run a thin-bladed paring knife between the sides of the pan and cake to loosen; cool the cake in the springform pan on a wire rack until barely warm, about 3 hours, then wrap the pan in plastic wrap and refrigerate until thoroughly chilled, at least 8 hours. (The cake can be refrigerated for up to 2 days.).
• 5. To unmold the cake, remove the sides of the pan. Slide a thin metal spatula between the.
• cake and pan bottom to loosen, then invert the cake onto a large plate, peel off the parchment, and re-invert onto a serving platter.
• If you like, dust the cake with confectioners' sugar just before serving or top slices with a dollop of lightly sweetened whipped cream. To make slicing easier, freeze the cake for 30 minutes just before serving.
• To serve, use a sharp, thin-bladed knife, dipping the knife in a pitcher of hot water and wiping the blade before each cut.

Steps:

• Adjust oven rack to lower-middle position and heat oven to 325 degrees. Butter sides of 9-inch spring-form pan; flour sides and tap out excess. Line bottom of pan with parchment or waxed paper round. Wrap bottom and sides of pan with large sheet of foil.
• Melt 12 tablespoons butter and chocolates in large bowl over large saucepan containing about 2 quarts barely simmering water, stirring occasionally, until chocolate mixture is smooth. Cool mixture slightly, then whisk in vanilla and egg yolks. Set chocolate mixture aside, reserving hot water, covered, in saucepan.
• In clean bowl of standing mixer fitted with whisk attachment, beat egg whites and salt at medium speed until frothy, about 30 seconds; add half of crumbled brown sugar, beat at high speed until combined, about 30 seconds, then add remaining brown sugar and continue to beat at high speed until soft peaks form when whisk is lifted, about 2 minutes longer. Using whisk, stir about one-third of beaten egg whites into chocolate mixture to lighten it, then fold in remaining egg whites in 2 additions using whisk. Gently scrape batter into prepared springform pan, set springform pan in large roasting pan, then pour hot water from saucepan to depth of 1 inch. Carefully slide roasting pan into oven; bake until cake has risen, is firm around edges, center has just set, and instant-read thermometer inserted into center registers about 170 degrees, 45 to 55 minutes.
• Remove spring-form pan from water bath, discard foil, and cool on wire rack 10 minutes. Run thin-bladed paring knife between sides of pan and cake to loosen; cool cake in springform pan on wire rack until barely warm, about 3 hours, then wrap pan in plastic wrap and refrigerate until thoroughly chilled, at least 8 hours. (Cake can be refrigerated for up to 2 days.).
• To unmold cake, remove sides of pan. Slide thin metal spatula between cake and pan bottom to loosen, then invert cake onto large plate, peel off parchment, and re-invert onto serving platter. To serve, use sharp, thin-bladed knife, dipping knife in pitcher of hot water and wiping blade before each cut.

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.

Steps:

• Make mousse: Put chocolate in a large bowl, and set aside. Heat 1 1/2 cups cream over medium-high heat in a medium saucepan until cream is steaming and small bubbles form on edges.
• Pour cream over chocolate. Stir until mixture is smooth. Let cool completely.
• Put remaining 1 1/2 cups cream and the sugar in the bowl of an electric mixer fitted with the whisk attachment; beat on medium-high speed until stiff peaks form. Using a rubber spatula, fold whipped cream into chocolate mixture, one-third at a time.
• Assemble torte: Line a 9-by-5-by-3-inch loaf pan with plastic wrap, leaving an overhang on sides. Spread enough mousse (3/4 to 1 cup) over bottom of pan to cover. Arrange 5 cookies on top in a single layer to cover, breaking them to fit as necessary. Spread enough mousse (3/4 to 1 cup) on top to cover; smooth into an even layer. Repeat process with remaining cookies and mousse until pan is full.
• Press plastic wrap directly onto surface, and refrigerate torte until firm, at least 3 hours or up to 2 days.
• Remove plastic wrap from surface. Invert torte onto a serving plate; unmold, using overhang to coax it out. Remove plastic wrap. Dust with cocoa.
