Mile High Chocolate Cake With Vanilla Buttercream Recipes

Steps:

• For cake:
• Butter three 8-inch-diameter cake pans with 1 1/2-inch-high sides. Line bottom of each pan with parchment paper round; butter parchment. Dust pans with flour; tap out excess. Whisk 11/4 cups hot water, cocoa powder, and sour cream in medium bowl until smooth; set aside until mixture is cool, 20 to 30 minutes.
• Position rack in center of oven and preheat to 325°F. Sift next 4 ingredients into another medium bowl. Using electric mixer, beat butter and shortening in large bowl until well blended and smooth. Add both sugars; beat until light and fluffy, about 5 minutes. Add eggs 1 at a time, beating until well blended after each addition. Mix in vanilla. Add flour mixture in 3 additions alternately with cocoa mixture in 2 additions, beginning and ending with flour mixture and beating just until incorporated. Divide batter among prepared pans (about 23/4 cups batter for each) and smooth tops.
• Bake cakes until tester inserted into center comes out clean, 50 to 55 minutes. Cool cakes in pans on racks 20 minutes. Run knife around sides of cakes to loosen. Invert cakes onto racks and cool completely. DO AHEAD: Can be made 1 day ahead. Wrap in plastic and store at room temperature.
• For vanilla buttercream:
• Combine egg whites and 1/3 cup sugar in large bowl of stand mixer fitted with whisk attachment; scrape in seeds from vanilla bean.
• Combine remaining 1 1/3 cups sugar and 1/3 cup water in medium saucepan. Stir over medium heat until sugar dissolves. Attach candy thermometer to side of pan, making sure that bulb of thermometer is immersed in syrup. Increase heat; boil until temperature registers 238°F to 240°F (soft-ball stage), about 5 minutes. Immediately remove syrup from heat (use within 2 minutes).
• Meanwhile, beat egg white mixture on medium speed until very soft peaks form (mixture will be slightly opaque).
• Increase mixer speed to high and slowly pour hot syrup down side of bowl into egg white mixture in slow steady stream; beat until meringue forms stiff peaks. Cool meringue in bowl until lukewarm (instant read thermometer will register 100°F), about 30 minutes. Do not beat.
• Start beating meringue again on medium speed of stand mixer. Gradually add butter, 2 to 3 tablespoons at a time, beating constantly until absorbed before adding next addition. Continue beating until buttercream is smooth. (If buttercream looks broken or curdled, place mixer bowl with buttercream over medium heat on stove burner and whisk with large whisk for 5 to 10 seconds to warm mixture slightly, then remove from heat and whisk vigorously or attach bowl to stand mixer and beat mixture again on medium speed. Repeat warming and beating buttercream mixture as many times as needed until buttercream is smooth and no longer curdled.)
• Using serrated knife, cut each cake in half horizontally, forming 6 cake layers. If necessary, trim any domed tops of cakes to form even layers. Place 1 cake layer on platter. Drop 3/4 cup buttercream by tablespoonfuls over top of cake layer, then spread evenly to edges with offset spatula. Top with second cake layer, then spread 3/4 cup buttercream over. Repeat with 3 more cake layers, spreading 3/4 cup buttercream over each and pressing slightly to adhere. Top with 6th cake layer (do not spread buttercream over top cake layer). Chill cake at least 1 hour.
• For chocolate glaze:
• Combine both chocolates in medium bowl. Bring cream and corn syrup to simmer in heavy saucepan. Pour hot cream mixture over chocolate; let stand 2 minutes. Whisk chocolate mixture until melted and smooth. Add butter; whisk until melted. Chill glaze until slightly thickened and glaze drips thickly when poured slowly from spoon, 30 to 45 minutes.
• Spoon glaze around top edge of cake by teaspoonfuls, spacing drips up to 2 inches apart and allowing glaze to drip slowly down sides of cake. Spoon remaining glaze over top center of cake and smooth with offset spatula, covering top completely. Chill cake until glaze sets, at least 1 hour. DO AHEAD: Can be made 1 day ahead. Tent with foil and keep chilled. Let cake stand at room temperature 1 hour before serving.

Steps:

• Preheat oven to 350 degrees and place rack in center. Butter two 8-by-2-inch round cake pans. Line with parchment paper. Butter the parchment, and dust with cocoa powder, tapping out excess. Sift cocoa over a medium bowl; whisk in boiling coffee and milk. Let cool; set aside. Sift together flour, baking soda, and salt into another medium bowl; set aside.
• In a large bowl, mix butter using a rubber spatula until light and fluffy, about 2 minutes. Gradually add sugar and vanilla. Add eggs one at a time, stirring well after each addition. Pour in cooled cocoa mixture. Mix until fully incorporated.
• Add flour mixture to chocolate mixture, stirring until just combined. Pour batter into prepared pans (about 4 cups in each pan). Bake for 20 minutes, rotate pans, and bake until a cake tester comes out clean when inserted into center of cake, 20 to 25 minutes.
• Remove cakes from oven, and transfer to a cooling rack. Allow to cool in pans for 15 minutes. Carefully run a small offset spatula around edge of cakes to loosen from pan. Invert cakes onto a wire rack. Let cook completely, about 1 hour.
• To assemble, using a serrated knife, level the top surface of each cake layer. Place four strips of parchment paper around the perimeter of the lazy susan. Place the first layer on the lazy susan. Spread with 3/4 cup buttercream. Top with the remaining layer, bottom-side up. Spread a thin layer of buttercream on the top and sides of cake, called a crumb coat. Chill until the buttercream is set, at least 30 minutes.
• Apply the final coat of buttercream. Smooth the sides with a bench scraper or large offset spatula held steady at a 45-degree angle while turning the lazy susan.

Steps:

• Make cake layers:
• Put oven rack in middle position and preheat oven to 350°F. Butter 2 (9- by 2-inch) round cake pans and line bottom of each with a round of wax paper. Butter paper and dust pans with flour, knocking out excess.
• Whisk together hot water and cocoa powder in a bowl until smooth, then whisk in milk and vanilla.
• Whisk together flour, baking soda, and salt in another bowl.
• Beat together butter and brown sugar in a large bowl with an electric mixer at medium-high speed until pale and fluffy, 3 to 5 minutes. Add eggs 1 at a time, beating well after each addition. Reduce speed to low and add flour and cocoa mixtures alternately in batches, beginning and ending with flour mixture (batter may look curdled).
• Divide batter between cake pans, smoothing tops. Bake until a wooden pick or skewer comes out clean and edges of cake begin to pull away from sides of pans, 25 to 35 minutes total. Cool layers in pans on racks 10 minutes, then invert onto racks, removing wax paper, and cool completely.
• Assemble cake:
• Put 1 cake layer, rounded side up, on a cake stand or platter and, using offset spatula, spread top with about 1 cup buttercream. Top with remaining cake layer, rounded side down, and frost side and top of cake with 2 cups buttercream.
• Decorate cake:
• For each color (you can make up to 5), transfer 3 tablespoons buttercream to a separate small bowl and tint with food coloring. Snip off 1 corner of each plastic bag to create a 1/4-inch opening, then spoon each color of buttercream into a bag, pressing out excess air. Twist each bag firmly just above buttercream, then decoratively pipe colored buttercream onto cake. Chill cake until buttercream is set, about 30 minutes.
• Just before serving, arrange 6 to 8 mini cupcakes on top of cake in 1 layer, then stack remaining mini cupcakes on top.
