Chocolate Meringue Cake With Coffee Buttercream Recipes

Steps:

• Preheat the oven to 350 degrees F. Butter and flour a 12 by 18 by 1 1/2-inch sheet pan.
• In a medium bowl, sift together the flour, cocoa, baking soda, and salt.
• In the bowl of an electric mixer fitted with a paddle attachment, cream the butter and sugars on high speed until light, approximately 5 minutes. Add the eggs and vanilla and mix well. Combine the buttermilk, sour cream, and coffee. On low speed, add the flour mixture and the buttermilk mixture alternately in thirds, beginning with the buttermilk mixture and ending with the flour mixture. Mix the batter only until blended.
• Pour the batter into the prepared sheet pan, smooth the top with a spatula, and bake in the center of the oven for 25 to 30 minutes, or until a toothpick comes out clean. Cool to room temperature before frosting.
• 2 cups sugar
• 2/3 cup water
• 6 extra-large egg whites, at room temperature
• 1/4 teaspoon cream of tartar
• 1 1/4 pounds (5 sticks) unsalted butter, at room temperature
• 2 teaspoons pure vanilla extract
• 3 tablespoons Triple Sec or other orange liqueur
• 1 tablespoon orange food coloring
• Combine the sugar with 2/3 cup water in a medium heavy-bottomed saucepan and, without stirring, bring to a boil. Cover the saucepan and allow the mixture to boil until the sugar dissolves. Uncover and continue boiling until the mixture reaches 240 degrees F on a candy thermometer. Pour the syrup into a heat-proof measuring cup.
• Place the egg whites and cream of tartar in the bowl of an electric mixer fitted with the whisk attachment and beat on high speed until the eggs form stiff peaks. With the mixer on high speed, slowly pour the syrup into the egg whites. Continue beating on high speed until the mixture is absolutely at room temperature, about 10 to 15 minutes.
• With the mixer on medium speed, add the butter, 1 tablespoon at a time, and then add the vanilla and liqueur. (If the mixture becomes runny, the meringue was too warm and the butter melted. Chill slightly and beat again.) Add the food coloring and combine.
• Yield: 6 cups

Steps:

• In medium glass or metal bowl, beat egg whites and sugar with whisk until blended. Set over pan of simmering water, beating occasionally, until sugar has dissolved and egg mixture reaches 160°F on candy thermometer, 16 to 20 minutes. Remove from heat.
• Pour into bowl of electric stand mixer fitted with whisk attachment. Beat on high speed 2 to 3 minutes or until glossy peaks form and bowl has cooled to feel slightly warm. Still on high speed, slowly add 1 1/2 cups softened butter, one piece at a time, scraping side of bowl occasionally, until mixture is smooth, thick and shiny, 12 to 14 minutes. Beat in vanilla. If mixture separates, beat until smooth.
• In small microwavable bowl, microwave chopped chocolate uncovered on High 60 seconds, stirring halfway through microwave time. Continue to microwave in 10-second increments, until chocolate can be stirred smooth. Let stand 10 minutes. Beat cooled melted chocolate into frosting until smooth.
• Fill and frost 1 (8-inch) three-layer cake.

Steps:

• Preheat the oven to 250 degrees F (120 degrees C).
• Mark out a 13x10-inch rectangle on parchment paper; place it on a baking sheet.
• Combine ground almonds, ground hazelnuts, 1/2 cup of caster sugar, cornstarch, and salt in a bowl.
• Whip egg whites and cream of tartar together in another bowl until foamy, then mix in the remaining 1/2 cup caster sugar until glossy and stiff. Fold in the nut-sugar mixture in two batches. Spread the meringue onto the parchment paper and mist the surface with water.
• Bake in the preheated oven for 90 minutes, then turn off the oven and leave the meringue inside for another 90 minutes. Remove to a wire rack to cool.
• Whisk egg yolks, confectioners' sugar, cornstarch, and salt for buttercream together in a bowl.
• Heat milk to a simmer. Pour milk into the yolk mixture, whisking until smooth. Return mixture to the heat and continue whisking until thickened and stiff. Transfer custard to a bowl, cover, and refrigerate until set, about 2 hours. Before using, bring to room temperature, about 30 minutes.
• Dissolve instant coffee in hot water.
• Whip butter in a bowl until light. Beat in the custard in 3 batches until just combined. Add coffee mixture and beat until light and fluffy.
• Place chocolate for ganache in a heat-proof bowl. Heat cream and corn syrup to a simmer in a small saucepan; then pour over the chocolate to soften. Stir until smooth and cool for 5 minutes.
• Peel off paper from meringue and transfer to a cutting board. Use a serrated knife to trim the edges and cut into 4 equal rectangles. Spread 3 rectangles each with about 1/4 cup ganache. Refrigerate until firm, about 1 hour.
• Spread remaining rectangle with about 1/2 cup buttercream; place on a wire rack. Place one ganache-coated meringue, chocolate-side down on top and press gently. Spread on 1/2 cup buttercream and repeat with the remaining meringue. Frost the top and sides of the cake with the remaining buttercream. Refrigerate until firm, about 1 hour more.
• Microwave remaining ganache in a microwave-safe bowl in 15-second intervals, until warm and runny. Pour over cake and garnish with whole hazelnuts.

Steps:

• Preheat oven to 250 degrees. Line 2 baking sheets with parchment paper. Using a marker, trace 10-inch circles on each sheet of parchment; turn paper marked-side down. In a large bowl, sift together confectioners' sugar and cocoa powder; set aside.
• In the bowl of an electric mixer fitted with the whisk attachment, beat egg whites on medium-high speed until foamy. Add the cream of tartar and whisk until soft peaks form. With mixer running, gradually add the granulated sugar, whisking until stiff glossy peaks form, 4 to 5 minutes. Sift in the confectioners' sugar and cocoa mixture in three additions, folding after each addition, until mostly incorporated.
• Transfer meringue to a large pastry bag fitted with a 1/2-inch plain tip. Starting just within the marked circles, pipe meringue, working inward in a spiral pattern. Bake for 2 hours. Turn off oven, allowing meringues to dry out until oven is completely cool, at least 4 hours and up to overnight.
