Triple Chocolate Sheet Cake Recipe 455

Steps:

• Heat oven to 350°F (325°F for dark or nonstick pan). Spray bottom and sides of 15x10x1-inch pan with baking spray with flour.
• In large bowl, beat cake mix, sour cream, water, cocoa, butter and eggs with electric mixer on low speed 30 seconds, then on medium speed 2 minutes, scraping bowl occasionally. Pour into pan.
• Bake 18 to 22 minutes or until toothpick inserted in center comes out clean. Cool about 45 minutes.
• Spoon frosting into small microwavable bowl. Microwave uncovered on High 20 to 30 seconds, stirring once, until pourable. Spread frosting over cake; sprinkle with pecans.

Steps:

• For the cake: Preheat the oven to 350 degrees F.
• In a large bowl, combine the flour, sugar and salt. Stir together and set aside.
• In another bowl, mix the buttermilk, baking soda, vanilla and eggs. Mix with a fork and set aside.
• In a medium saucepan, melt the butter and add the cocoa. Whisk together to combine. Meanwhile, bring 1 cup water to a boil. When the butter is melted, pour the boiling water in the pan. Allow to bubble for a moment, then turn off the heat. Pour the chocolate mixture into the flour mixture. Stir together for a moment to cool the chocolate, then pour in the egg mixture. Stir together until smooth, then pour into an ungreased jelly roll pan (or rimmed baking sheet) and bake for 20 minutes.
• While the cake is baking, make the icing: Melt the butter in a saucepan over medium-low heat. Add the cocoa powder and stir until smooth. Add the milk, vanilla and powdered sugar. Stir together. Dump in the pecans and stir until well combined.
• Immediately after removing the cake from the oven, pour the warm icing over the top. You'll want to avoid doing much spreading, so try to distribute it evenly as you pour.

Steps:

• Allow butter and eggs to stand at room temperature for 30 minutes. Meanwhile, lightly grease bottoms of three 8-inch round baking pans or two 8x8x2-inch square or 9x1-1/2-inch round cake pans. Line bottom of pans with parchment paper. Grease and lightly flour parchment paper and sides of pans. Or grease one 13x9x2-inch baking pan. Set pan(s) aside.
• Preheat oven to 350 degrees F. In a medium mixing bowl, stir together flour, cocoa powder, baking soda, baking powder and salt; set aside.
• In a large mixing bowl, beat butter with an electric mixer on medium to high speed for 30 seconds. Gradually add granulated sugar, about 1/4 cup at a time, beating on medium speed until well combined (3 to 4 minutes). Scrape sides of bowl; continue beating on medium speed for 2 minutes. Add eggs, one at a time, beating after each addition (about 1 minute total). Beat in vanilla.
• Alternately add flour mixture and milk to beaten mixture, beating on low speed just until combined after each addition. Beat on medium to high speed for 20 seconds more. Spread batter evenly into the prepared pan(s).
• Bake for 35 to 40 minutes for 8-inch square pans and the 13x9x2-inch pan, 30 to 35 minutes for 8- or 9-inch round pans, or until a wooden toothpick inserted in the center comes out clean. Cool cake layers in pans for 10 minutes. Remove from pans. Peel off parchment paper. Cool thoroughly on wire racks. Or place 13x9x2-inch cake in pan on a wire rack; cool thoroughly. Frost with desired frosting.
• To prepare frosting, in a large saucepan, melt semisweet chocolate chips and butter over low heat, stirring frequently. Cool for 5 minutes. Stir in sour cream. Gradually add powdered sugar, beating with an electric mixer until smooth. This frosts tops and sides of two or three 8- or 9-inch cake layers. (Halve the recipe to frost the top of a 13x9x2-inch cake.) Cover and store frosted cake in the refrigerator.

Steps:

• Heat oven to 325°F. Grease 9-inch round cake pan. In 2-quart heavy saucepan, melt 1 cup of the chocolate chips and 1/2 cup butter over low heat, stirring constantly; cool 5 minutes. Stir in flour until smooth. Stir in egg yolks until well blended.
• In large bowl, beat egg whites with electric mixer on high speed until foamy. Beat in sugar, 1 tablespoon at a time, until soft peaks form. Fold chocolate mixture into egg whites. Spread in pan.
• Bake 30 to 35 minutes or until toothpick inserted in center comes out clean (top will appear dry and cracked). Cool 10 minutes. Run knife around edge of pan to loosen; remove cake from pan to cooling rack. Cool completely, about 1 hour. Place cake on serving plate.
• In 1-quart saucepan, heat remaining 1/2 cup chocolate chips, 2 tablespoons butter and the corn syrup over low heat, stirring constantly, until chocolate chips are melted. Spread over top of cake, allowing some to drizzle down side.
• In 1-quart saucepan, melt glaze ingredients over low heat, stirring constantly. Drizzle over top of cake.

Steps:

• In a large bowl, combine cake and pudding mixes, milk and eggs at low speed until dry ingredients are moistened. Beat at medium speed for 2 minutes. Stir in chocolate chips. Pour into a greased and floured 10-in. tube or fluted tube pan. Bake at 350° for 60 minutes or until cake tests done. Cool in pan for 10 minutes before removing to a wire rack.

Steps:

• Make cake:
• Position rack in center of oven and preheat to 350°F. Butter and flour two 10-inch-diameter cake pans with 2-inch-high sides; line each with round of parchment paper or waxed paper. Combine first 5 ingredients in medium bowl; whisk to blend well. Using electric mixer, beat sugar, eggs and egg yolks in large bowl until very thick and heavy ribbon falls when beaters are lifted, about 6 minutes. Add oil, sour cream and vanilla, then dry ingredients all at once to egg mixture. Beat at low speed until just blended, about 1 minute. Scrape down sides of bowl. Beat at high speed until well blended, about 3 minutes. Fold in chocolate chips; divide batter between prepared pans (about 3 3/4 cups batter in each).
• Bake cakes until tester inserted into center comes out clean, about 40 minutes. Cool cakes completely in pans on racks. Cover; let cakes stand at room temperature overnight.
• Make ganache:
• Bring cream to simmer in heavy large saucepan over medium-high heat. Remove from heat. Add chocolate and whisk until melted and smooth. Transfer ganache to glass bowl. Let stand until thick enough to spread, about 4 hours. (Can be made 1 day ahead. Cover; chill.)
• Make mousse:
• Using electric mixer, beat 3 1/3 cups cream in large bowl until peaks form; refrigerate. Combine remaining 1 cup cream and corn syrup in heavy medium saucepan and bring to simmer. Remove from heat. Add chocolate and whisk until melted, smooth, and still warm to touch. Pour warm chocolate mixture directly onto whipped cream and fold in gently. Chill until mousse is set, at least 8 hours. (Can be prepared 1 day ahead. Cover and keep refrigerated.)
• Assemble and serve cake:
• Cut around pan sides; turn out cakes. Peel off paper. Cut each cake horizontally in half. Place 1 cake layer, cut side up, on 9-inch tart pan bottom or 9-inch cardboard round. Place another layer, cut side up, on clean baking sheet. Spread each with 1/3 cup raspberry jam. Chill until jam sets, about 15 minutes
• If ganache is chilled, microwave on defrost setting in 15-second repetitions until just soft enough to spread, stirring occasionally. Drop 1 cup ganache by rounded teaspoonfuls over each jam layer. Using offset spatula, gently spread ganache to cover jam. Drop 3 cups mousse by heaping spoonfuls onto each ganache layer; gently spread to cover. Refrigerate cake layers 30 minutes. Using large metal spatula, place cake layer from baking sheet, mousse side up, atop cake layer on tart pan bottom. Place third cake layer, cut side down, on cake (reserve remaining cake layer for another use). Spread 1 cup mousse over top of assembled cake. Using long offset spatula, spread sides of assembled cake with enough ganache (about 1 1/2 cups) to fill gaps and make smooth surface. Transfer cake on tart pan bottom to platter.
• Turn 1 large baking sheet upside down on work surface. Arrange two 20-inch-long pieces of foil on work surface. Cut two 4 1/2-inch-wide by 15 3/4-inch-long strips from transfer sheet. Lay 1 transfer sheet strip, rough-textured design facing up, onto each sheet of foil. Place chocolate in medium metal bowl; set bowl over saucepan of simmering water (do not allow bottom of bowl to touch water). Stir until chocolate is smooth and very warm to touch (about 115°F). Remove bowl from over water.
• Pour thick ribbon of melted chocolate (about 2/3 cup) onto 1 transfer sheet strip. Using long offset spatula, spread chocolate evenly over transfer strip, covering completely (chocolate will run over sides of strip). Lift edge of chocolate-coated strip with tip of knife. Slide hands between transfer strip and foil, lift entire transfer strip and place it, chocolate side up, on inverted baking sheet. Refrigerate until chocolate on strip is set and loses gloss but is still flexible (do not let chocolate become too firm), about 1 1/2 minutes. Using fingertips, lift chocolate-coated strip and attach, chocolate side in, to side of cake. Press strip to seal chocolate to side of cake (strip will stand about 1 inch above top edge of cake). Coat remaining transfer strip with chocolate, transfer to inverted baking sheet; chill until set but still flexible. Arrange 1 end of second strip against (but not overlapping) 1 end of first strip. Press second strip to seal chocolate to side of cake (both strips will just encircle cake). Refrigerate cake until chocolate strips are firm, about 30 minutes. Carefully peel transfer paper off chocolate strips. Chill cake at least 3 hours and up to 1 day. Mound fruit atop cake. Refrigerate until ready to serve. (Cake can be assembled up to 8 hours ahead.)
