Chocolate Chestnut Mousse Cake Recipes

CHOCOLATE-CHESTNUT MOUSSE CAKE

Steps:

• Lightly coat an 8-inch round cake pan with oil, and line with plastic, leaving a 4-inch overhang.
• Finely grind chestnuts in a food processor. Heat ground chestnuts, milk, 3 tablespoons sugar, and the salt in a medium saucepan over medium-high heat, stirring occasionally, until bubbles form at edge.
• Whisk together yolks, cornstarch, and remaining 2 tablespoons sugar in a medium heatproof bowl.
• Slowly add hot chestnut mixture to yolk mixture, whisking constantly. Return to pan; cook over medium-low heat, whisking constantly, until thick, about 2 minutes. Transfer to the bowl of a mixer. Add vanilla and butter. Beat on medium speed until cool, about 5 minutes. Stir half the chestnut mixture into melted chocolate.
• Beat 1 1/4 cups cream until soft peaks form. Using a rubber spatula, gently fold half the whipped cream into plain chestnut mixture and the other half into chocolate-chestnut mixture.
• Pour chestnut mousse into prepared pan. Cover with 12 chocolate wafers, working in a circular pattern. Top with chocolate-chestnut mousse and remaining 12 chocolate wafers. Fold plastic overhang over top to cover cake. Refrigerate overnight.
• Uncover cake; place a platter on top, flip, and unmold. Remove plastic. Beat remaining 1/4 cup cream until soft peaks form. Spread on top of cake. Garnish with chocolate shavings.

CHOCOLATE-CHESTNUT MOUSSE

Steps:

• Bring chestnuts, milk, sugar, vanilla, and salt to a boil over high heat in a small saucepan. Reduce heat, bring to a simmer, and cook, stirring occasionally, until milk is reduced by one-quarter and chestnuts smash fairly easily against the side of the pot with the back of a spoon, 15-17 minutes.
• Meanwhile, finely chop 4 oz. chocolate. Using a peeler, shave remaining 1 oz. chocolate; set aside until ready to serve.
• Purée chestnut mixture in a blender on high speed until very smooth, about 2 minutes. Add chopped chocolate and 1 tsp. brandy and blend on high speed until chocolate is melted, about 30 seconds. Scrape into a large bowl and let cool to room temperature, stirring occasionally (if lumps form, stir vigorously until smooth), 15-20 minutes.
• Whip 2 cups cream with a whisk in another large bowl until it just barely holds soft peaks. Stir one-third of cream into chocolate mixture to lighten it, then fold in remaining cream just until incorporated. Transfer mousse to a large serving bowl, cover, and chill at least 2 hours or up to 1 day.
• Whip remaining 1 cup cream and 1/2 tsp. brandy with whisk in a large bowl to medium peaks. Garnish mousse with reserved chocolate shavings and serve with whipped cream alongside.
• Do ahead
• Mousse can be made 1 day ahead; cover and chill.

CHOCOLATE CHESTNUT TORTE WITH CHOCOLATE COGNAC MOUSSE

Steps:

• Make ganache:
• Bring cream and butter to a simmer in a 3- to 4-quart heavy saucepan, then reduce heat to low. Whisk in chocolate until smooth and remove from heat. Transfer ganache to a bowl and chill, covered, stirring every 30 minutes, until thickened but spreadable, about 2 hours. (If ganache becomes too stiff, let stand at room temperature until slightly softened.)
• Make cake layers while ganache chills:
• Preheat oven to 350°F. Butter cake pans and line bottom of each with a round of parchment or wax paper. Butter paper and dust pans with flour, knocking out excess flour.
• Pulse chestnuts with flour, baking soda, and salt in a food processor until finely ground.
• Beat butter and brown sugar in a large bowl with an electric mixer at medium-high speed until pale and fluffy, about 3 minutes in a standing mixer or about 6 minutes with a handheld. Add eggs 1 at a time, beating well after each addition, then beat in vanilla (mixture will look a little separated). Reduce speed to low and add flour mixture and sour cream alternately in 3 batches, beginning and ending with flour and mixing until just combined.
• Divide batter evenly among pans and bake in middle of oven until pale golden and springy to the touch, about 30 minutes. Cool cakes in pans on racks, then invert onto racks and remove parchment.
• Make mousse and assemble torte:
• Melt butter and chocolate in a double boiler or a metal bowl set over a saucepan of barely simmering water, stirring until smooth, and stir in Cognac. Transfer to a bowl and chill, covered, stirring occasionally, until thickened to the consistency of softened butter, about 1 hour. (If mixture becomes too stiff, let stand at room temperature until softened.)
• Beat cream in a bowl with cleaned beaters until it just holds soft peaks, then chill, covered, while beginning to assemble torte.
• Put 1 cake layer on cardboard round on a rack set in a shallow baking pan (1 inch deep). Spread 1/2 cup ganache evenly over top of layer and sprinkle with all of chopped marrons glacés. Top marrons glacés with another 1/4 cup ganache and cover with another cake layer.
• Beat egg whites with a pinch of salt using cleaned beaters at medium-high speed until they just hold soft peaks. Add sugar and beat at high speed until whites just hold stiff peaks. Stir whipped cream into chocolate Cognac mixture, then stir in one third of whites to lighten. Fold in remaining whites gently but thoroughly. Spoon mousse immediately onto cake layer (it sets quickly), spreading evenly, then top with third cake layer. Chill torte, covered, until mousse layer is firm, about 1 hour. Keep remaining ganache at a spreadable consistency at room temperature, chilling, covered, if it becomes too soft.
• Glaze cake:
• Reserve 1 1/4 cups ganache in a metal bowl, then spread remainder over top and side of torte to seal in crumbs. Chill until firm, about 1 hour.
• Set bowl of reserved ganache over a saucepan of barely simmering water, stirring until ganache reaches a pourable consistency. Remove bowl from heat and cool 5 minutes. Pour ganache evenly over top of torte, making sure it coats all of side. Shake rack gently to smooth glaze (let excess drip into baking pan). Transfer cake on cardboard to a cake stand or plate using 2 large heavy metal spatulas and chill until set. Garnish just before serving.

BAKED CHOCOLATE MOUSSE CAKE

Steps:

• Preheat the oven to 325 degrees F (165 degrees C).
• Mix boiling water and cocoa powder for cake together in a small mixing bowl until smooth. Let cool, about 10 minutes.
• Meanwhile, sift flour, sugar, baking soda, and salt together in a large bowl. Make a well in the center, pour in oil, egg yolks, vanilla extract, and cooled cocoa mixture. Mix using a wooden spoon just until smooth.
• Sprinkle cream of tartar over egg whites in a large mixing bowl. Beat using an electric mixer on high speed until very stiff peaks form. Pour cake batter over egg white mixture and fold gently using a whisk with an under-and-over motion; be sure not to overmix, but to also fully incorporate ingredients. Pour batter into an ungreased 10-inch tube pan.
• Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 1 hour. Let cake cool in the pan for 1 1/2 hours. Loosen with a spatula and transfer to a plate.
• Add cold water to a glass bowl and sprinkle gelatin on top; allow to soften. Place bowl over a saucepan filled with simmering water. Heat and stir until gelatin is fully dissolved, 2 to 3 minutes. Remove from heat and let cool.
• Combine heavy cream, confectioners' sugar, cocoa, vanilla extract, and salt in a large bowl. Refrigerate for 1 hour. Beat mixture using an electric mixer until stiff; keep mousse in refrigerator until needed.
• Cut a 1-inch slice crosswise from the top of the cooled cake and set aside. Outline a cavity in the cake using a sharp knife, leaving 1-inch walls around cake side and bottom. Carefully remove cake from the cavity using a spoon; reserve.
• Measure 2 1/2 cups of mousse filling and fold in gelatin. Fill the cake cavity and replace top of cake. Mix 1/2 cup filling with cake crumbs and fill center hole of cake. Frost the top and sides with remaining filling. Refrigerate until set, 2 to 3 hours.
