Chocolate Chip Cake With Toffee Sauce Chocolate Ganache And Vanilla Ice Cream Buttercream Recipes

Steps:

• Place chocolate chips in a small bowl. In a small saucepan, bring cream just to a boil. Pour over chocolate; whisk until smooth., For a pourable ganache, cool, stirring occasionally, until mixture reaches 85°-90° and is slightly thickened, about 40 minutes. Pour over cake, allowing some to drape down the sides. Spread ganache with a spatula if necessary to evenly coat, working quickly before it thickens. Let stand until set., For spreadable ganache, chill, stirring occasionally, until mixture reaches a spreading consistency. Spread over cake.

Steps:

• Make the cake: Preheat the oven to 350˚ F. Butter and flour two 9-inch round cake pans and line the bottoms with parchment paper. Put the cocoa powder and chocolate in a medium bowl. Add the boiling water and whisk until the chocolate is melted. Whisk in the sour cream until smooth; let cool to room temperature.
• Whisk the flour, baking soda and salt in a medium bowl; set aside. Beat the butter, granulated sugar and brown sugar in a large bowl with a mixer on medium-high speed until fluffy, 3 to 4 minutes. Add the eggs, one at a time, then the vanilla, beating well after each addition. Reduce the mixer speed to low. Beat in the flour mixture in 3 additions, alternating with the cocoa mixture in 2 additions. Finish mixing gently with a rubber spatula, scraping the bottom and sides of the bowl.
• Divide the batter evenly between the cake pans. Tap the pans against the counter to eliminate any air bubbles. Bake until the cakes spring back in the center when gently pressed, 35 to 40 minutes. Let the cakes cool in the pans for 10 minutes, then run an offset spatula around the edges and turn out the cakes onto a rack to cool completely. Remove the parchment.
• Make the frosting: Bring a few inches of water to a simmer in a medium saucepan over medium heat. Whisk the egg whites, granulated sugar and salt in the bowl of a stand mixer. Set the bowl over the saucepan (do not let the bottom of the bowl touch the water); cook, whisking, until the sugar dissolves, the egg whites are frothy and the mixture is warm, 3 to 5 minutes.
• Transfer the bowl to the stand mixer and beat with the whisk attachment on medium-high speed until stiff glossy peaks form and the mixture cools to room temperature, about 5 minutes. With the mixer running, add the butter a few pieces at a time, waiting for them to incorporate before adding more. (The mixture will become liquidy, then it will get thick and shiny once the butter emulsifies. It may also look curdled as you add the butter. It's OK: Keep adding butter and beating.) Add the vanilla and beat until combined and fluffy, 3 to 5 more minutes.
• Cut each cake in half horizontally to create 4 layers. Place 1 layer on a cake stand or serving plate. Spread about 2/3 cup frosting on top, then repeat with the remaining cake layers, spreading more frosting in between them. Spread a thin layer of frosting on the top and sides of the cake (this is the crumb coat - it doesn't have to be perfect), then refrigerate until the frosting sets, about 30 minutes. Spread the remaining frosting all over the top and sides of the cake, smoothing it with a bench scraper.
• Make the ganache: Heat the heavy cream in a saucepan over medium-high heat until steaming, then pour over the chocolate in a small heatproof bowl. Let sit for 5 minutes, then stir until smooth. Set aside until cool but still pourable, 20 to 40 minutes (the time will vary depending on the temperature and bowl). Pour the ganache on top of the cake and spread with a small offset spatula, letting it drip down the sides. Let the ganache set 20 to 30 minutes before slicing.

Steps:

• For cake:
• Position rack in center of oven and preheat to 375°F. Lightly butter two 9-inch-diameter cake pans with 1 1/2-inch-high sides. Line bottom of pans with parchment paper. Combine chocolate and 2 tablespoons water in top of double boiler set over simmering water. Stir until chocolate is smooth. Remove from over water. Transfer chocolate to large bowl; cool 5 minutes. Whisk egg yolks into chocolate. Beat whites in medium bowl until soft peaks form. Add sugar 1 tablespoon at a time, beating until stiff and glossy. Fold 1/4 of whites into chocolate to lighten. Gently fold in remaining whites in 2 additions just until combined and being careful not to deflate batter.
• Divide batter between prepared pans (layers will be very thin). Bake until cakes begin to pull away from sides of pans and tester inserted into center comes out clean, about 10 minutes. Cool cakes in pans on rack 1 hour. Carefully invert cakes onto 9-inch-diameter cardboard rounds or tart pan bottoms. Cool cakes completely. Peel off parchment paper.
• For filling:
• Line 9-inch-diameter cake pan with 1 1/2-inch-high sides with plastic wrap, leaving 5-inch overhang. Whisk egg yolks, 1/4 cup sugar, and Kahlúa in medium metal bowl to blend. Set bowl over saucepan of simmering water (do not allow bottom of bowl to touch water). Using electric mixer, beat until yolk mixture is thick and instant-read thermometer inserted into mixture registers 140°F for 3 minutes, about 9 minutes total. Remove bowl from over water. Continue to beat mixture until cool to touch, about 3 minutes. Beat whipping cream and espresso powder in another medium bowl until firm peaks form. Fold cream mixture into yolk mixture in 2 additions. Using clean dry beaters, beat egg whites in large bowl until soft peaks form. Gradually add remaining 1/4 cup sugar and beat until stiff and glossy. Gently fold whites into yolk mixture in 2 additions. Fold in chopped chocolate. Carefully place 1 cake layer in prepared pan (cake layer is very delicate). Spread filling evenly over cake (filling layer will be thick). Top with second cake layer; press gently to adhere. Fold plastic overhang over cake, then cover with foil. Freeze cake overnight. (Can be made 3 days ahead. Keep frozen.)
• For glaze:
• Bring first 3 ingredients to simmer in small saucepan. Remove from heat. Add chocolate; whisk until smooth. Transfer 1/2 cup glaze to small bowl; chill until cool and very slightly thickened but easily spreadable (if too thick, glaze will not spread smoothly on frozen cake), about 10 minutes.
• Remove foil and plastic wrap from top of cake. Invert cake onto 9-inch-diameter cardboard round or tart pan bottom; place on rack set over rimmed baking sheet. Working quickly, spread thin layer of chilled glaze over top and sides of cake. Freeze until glaze is set, about 1 hour.
• Rewarm remaining glaze over low heat until just warm and pourable. Transfer to 1-cup measuring cup. Pour half of glaze over top of cake. Working quickly and using offset spatula, spread glaze over top, allowing excess to run down sides of cake; spread quickly over sides (glaze will harden quickly on frozen cake). Pour remaining glaze over top of cake; spread quickly and smoothly over top and sides. Sprinkle coffee beans around top edge of cake. Freeze until firm and glaze is set, at least 4 hours. (Can be made 3 days ahead. Cover; keep frozen.)
• To serve, dip long thin sharp knife into hot water, then wipe dry and cut cake into wedges, pulling knife out at bottom of cake to avoid tearing glaze and repeating for each slice.
