Chocolate Meringue For Chocolate Meringue Cake With Coffee Buttercream Recipes

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 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.

Steps:

• Preheat oven to 350 degrees. Butter a 9-by-3-inch springform pan. Line bottom with parchment. Butter parchment, and sprinkle with flour; tap out excess. Set aside.
• Spread hazelnuts in a single layer on a rimmed baking sheet. Toast until fragrant and skins start to crack, 10 to 15 minutes. Remove from oven; rub vigorously with a clean kitchen towel to take off skins. Let cool; roughly chop. Set aside.
• Make cake batter: In the bowl of an electric mixer fitted with the paddle attachment, cream butter and brown sugar until pale and smooth. Add egg yolks, one at a time, beating well after each addition, until mixture is light and fluffy. Add melted chocolate, vanilla, and rum, if using; beat until combined. Set aside.
• In a clean mixer bowl, combine 6 egg whites and salt; using the whisk attachment, beat on high speed until soft peaks form, about 2 minutes. Stir one-third of the egg whites into chocolate mixture. Fold in remaining beaten egg whites just until combined. Pour batter into prepared pan, and bake 25 minutes.
• Meanwhile, make meringue: Combine hazelnuts, chopped chocolate, and cornstarch in a small bowl, and set aside. Place remaining 4 egg whites and cream of tartar in a clean mixer bowl; using a clean whisk attachment, beat on high speed until frothy. With mixer running, slowly add superfine sugar; continue beating until stiff peaks form, about 8 minutes. Fold in hazelnut mixture.
• Remove cake from oven. Using an offset spatula, spread meringue mixture on top of cake, and return to oven. Bake until meringue is lightly browned and crisp, 25 to 30 minutes. Transfer pan to a wire rack; let stand 10 minutes. Run a knife around the edge of the cake to loosen, and release sides of pan. Let cool, about 30 minutes, before slicing and serving.
