Devils Food Cake With Black Pepper Boiled Icing

DEVIL'S FOOD CAKE WITH BLACK PEPPER BUTTERCREAM

Steps:

• Make the cake: Heat oven to 350 degrees. Grease 3 8-inch round baking pans, line the bottoms of each with a round of parchment paper and grease the paper. Use a little cocoa powder to coat the insides of the pans, rotating pans so the cocoa comes up the sides, then tap out excess.
• In a small bowl, whisk together cocoa powder and 2/3 cup boiling water. Whisk in milk. In a separate bowl, whisk together cake flour, baking soda, baking powder and salt.
• In a large mixing bowl fitted with the paddle attachment, beat butter and sugar until fluffy. Beat in eggs 1 at a time, until incorporated. Beat in vanilla. With the mixer running on low speed, beat in a third of the dry ingredients, followed by half the cocoa mixture. Add remaining portions, alternating between two mixtures. Beat until smooth.
• Divide batter evenly among prepared pans. Bake until the centers of the cakes are firm to the touch, 30 to 40 minutes. Cool cakes in their pans on a wire rack for 10 minutes; turn them out onto the rack to cool completely. (Peel off parchment paper if it sticks to the cakes.)
• Make the buttercream: Fill a medium pot halfway with water (or use a double-boiler) and bring to a simmer. In a heatproof bowl that fits over pot, whisk together egg whites, sugar and salt. Cook, whisking constantly, until the sugar dissolves and mixture reaches 140 degrees on a candy or instant-read thermometer, about 5 minutes.
• Using an electric mixer, whip until completely cooled and thick, about 5 minutes. Beat in butter a little at a time, until the frosting is smooth and spreadable. Beat in vanilla bean seeds and pepper.
• Using a serrated knife, slice each cake in half horizontally. Place one bottom layer on a large platter or cake stand. Top evenly with a thin layer of buttercream. Repeat, alternating between cake and frosting, ending with a layer of cake. Cover cake loosely with plastic wrap and refrigerate while you prepare fudge frosting. (Cake can rest in the refrigerator for up to 1 day.)
• Make the frosting: In a medium saucepan over medium heat, combine sugar, heavy cream and salt. Simmer, stirring occasionally, until sugar completely dissolves, about 5 minutes. Scrape mixture into a bowl. Stir in chocolate, butter and vanilla until smooth. Set bowl over a larger bowl filled with ice. Use a hand mixer or an immersion blender with the whisk attachment to whip until mixture is thick and cool, about 5 minutes. Spread frosting over the top and sides of the cake.

Steps:

• Make the filling: In the bowl of an electric mixer, combine chocolate and salt; set aside. Place 1 tablespoon heavy cream in a small bowl; sprinkle gelatin over cream and let stand until softened, about 10 minutes.
• Meanwhile, place remaining 3/4 cup plus 3 tablespoons heavy cream and 1 tablespoon sugar in a small saucepan and bring to a simmer over medium heat, stirring, until sugar has dissolved. In a medium bowl, whisk together egg yolks and remaining tablespoon sugar. Gradually whisk hot cream mixture into egg mixture. Return cream mixture to saucepan and place over medium heat; cook, whisking constantly, until mixture is thickened and coats the back of a spoon, about 3 minutes. Remove from heat.
• Stir gelatin mixture into cream mixture. Strain gelatin mixture into bowl with chocolate mixture; let stand 1 minute. Whisk until chocolate is melted and smooth. Whisk in creme fraiche. Attach bowl to electric mixer fitted with the whisk attachment and beat filling until well combined, about 2 minutes. Cover with plastic wrap, pressing down on the surface of the filling to prevent a skin from forming. Transfer to refrigerator and let chill overnight.
• Make the cake: Preheat oven to 350 degrees. Spray the bottom and sides of three 9-inch round cake pans with cooking spray. Line bottom of pans with parchment-paper rounds; set aside.
• Sift cocoa powder into a medium bowl; whisk in egg and egg white. Gradually whisk in 1/4 cup plus 2 tablespoons lukewarm water; continue whisking until smooth. Set aside. In another medium bowl, whisk together both flours, baking soda and baking powder; set aside.
• In the bowl of an electric mixer fitted with the paddle attachment, beat together brown sugar, butter, vanilla, and salt, until smooth, about 2 minutes, scraping down the sides of the bowl as necessary. Gradually beat cocoa mixture into butter mixture. Add flour mixture in three additions, alternating with buttermilk, and mixing well after each addition. Fold in cocoa nibs and ground espresso.
• Divide batter evenly among prepared cake pans; smooth tops. Transfer to oven and bake until a cake tester inserted into the center of each comes out clean, about 17 minutes. Transfer pans to wire rack and let cool completely before inverting cakes onto wire racks. At this point, cakes can be wrapped individually in plastic wrap and kept at room temperature for up to 1 day. Transfer cake layers to freezer; freeze until firm before frosting.
• Assemble: Place Chocolate Crumb Base on a cake plate; using an adjustable cake ring as a guide, top with 1 layer of cake. Stir filling to loosen and spread half (about 1 cup) over layer; top with a second layer, followed by remaining filling. Top with remaining layer of cake. Transfer to refrigerator and let chill for 1 hour.
• Spoon icing over top of cake; smooth over top and sides, swirling decoratively. If desired, use a kitchen torch to brulee frosting in several spots. Cake can be served immediately or covered with a cake dome and kept chilled for up to 1 day; let stand at room temperature for 1 hour before serving.

BLACK PEPPER ICING

Steps:

• In a small bowl, combine 1 tablespoon sugar and salt; set aside.
• Place remaining sugar in a small saucepan, along with 1/2 cup water. Place over medium-low heat and cook, stirring, until sugar dissolves. Increase heat and bring to a boil; do not stir. Cook, occasionally swirling and brushing down sides of saucepan with a moistened pastry brush, until mixture registers 240 degrees on a candy thermometer, about 10 minutes.
• Meanwhile, place egg whites in the bowl of an electric mixer fitted with the whisk attachment; beat on medium speed until frothy. With the mixer running, gradually add sugar and salt mixture.
• Increase mixer speed to medium-high; slowly add hot sugar mixture, allowing it to drizzle down the sides of the bowl. Continue beating until whites are stiff and cooled, about 20 minutes. Add pepper; mix until well combined. Use icing immediately.
