Cocoa Cake Roll Recipes

Steps:

• Make the cake: Preheat the oven to 375 degrees F. Coat an 11-by-17-inch rimmed baking sheet or jelly roll pan with cooking spray; line the bottom with parchment paper and spray the parchment. Beat the egg whites and cream of tartar with a mixer on medium speed until soft peaks form, 3 minutes. Gradually beat in 1/4 cup granulated sugar. Increase the speed to medium high; beat until stiff peaks form, 3 to 4 minutes.
• Whisk the egg yolks with the remaining 1/2 cup granulated sugar, the oil, milk, vanilla and espresso powder in a large bowl. Sift the flour, cocoa powder, baking powder and salt into a medium bowl; whisk into the yolk mixture until smooth. Stir one-third of the egg whites into the batter with a rubber spatula, then gently fold in the remaining whites in two batches. Spread the batter in the prepared pan; bake until the cake springs back when gently pressed, 10 to 12 minutes. Let cool 5 minutes.
• Generously sift cocoa powder over the top of the warm cake and loosen the edges with a knife; lay a clean kitchen towel (not terry cloth) over the cake. Place another baking sheet over the towel and flip the cake with the baking sheets to invert it onto the towel. Remove the top baking sheet and parchment, then dust the cake with cocoa powder. Starting at a short end, roll up the cake and the towel together into a spiral. Transfer seam-side down to a rack and let cool completely.
• Meanwhile, make the filling: Beat the butter and salt in a large bowl with a mixer on medium speed until creamy, 2 minutes. Add 1 1/2 cups marshmallow cream and the vanilla; increase the speed to medium high and beat until fluffy, 2 minutes. Reduce the speed to low. Beat in the confectioners' sugar, then the milk, then increase the speed to medium and beat until thick and spreadable.
• Gently unroll the cake. Spread the filling over the cake about 1/4 inch from the edges; reroll (without the towel). Trim the ends with a serrated knife, then transfer to a rack set on a baking sheet.
• Make the glaze: Microwave the chocolate with the heavy cream in a microwave-safe bowl, stirring every 30 seconds, until smooth. Pour over the cake; spread to coat. Transfer to a platter and refrigerate 15 minutes.
• Microwave the remaining 1/4 cup marshmallow cream in a microwave-safe bowl, stirring every 5 seconds, until loose. Drizzle over the cake.

Steps:

• Place egg whites in a small bowl; let stand at room temperature for 30 minutes. In a large bowl, beat egg yolks on high speed until light and fluffy. Gradually add 1/2 cup sugar, beating until thick and lemon-colored. Stir in vanilla. combine the flour, cocoa and salt; add to egg yolk mixture until blended., Beat egg whites on medium until foamy. Add cream of tartar; beat until soft peaks form. Gradually add remaining sugar, 1 tablespoon at a time, beating on high until stiff peaks form. Stir a fourth of the egg white mixture into chocolate mixture. Fold in remaining egg white mixture. , Line a greased 15x10x1-n. baking pan with parchment; grease the paper. Spread batter evenly in pan. Bake at 350° for 12-15 minutes or until cake springs back when lightly touched in center (do not overbake). Cool for 5 minutes; invert onto a kitchen towel dusted with confectioners' sugar. Gently peel off parchment. Roll up cake in the towel jelly-roll style, starting with a short side. Cool completely on a wire racks., In a large bowl, beat cream and confectioners' sugar until stiff peaks form; chill. Unroll cake; spread with whipped cream to within 1/2 in. of edges. Roll up again. Place seam down on serving platter; chill. Dust with additional confectioners' sugar before serving.

Steps:

• Place a rack in middle of oven; preheat to 350°F. Line bottom of a 17x12" rimmed baking sheet with parchment paper (do not grease pan or parchment). Separate yolks from 4 large eggs, room temperature, over a medium bowl to catch egg whites. Place yolks in a large bowl and set aside.
• Add 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt, ½ tsp. cream of tartar, and ½ cup (100 g) granulated sugar to egg whites and beat with an electric mixer until sugar is dissolved and egg whites are glossy and stiff peaks form, 8-10 minutes. (You can also beat on medium-high speed in the bowl of a stand mixer fitted with the whisk attachment.)
• Add remaining ½ cup (100 g) granulated sugar to reserved egg yolks and whisk to combine, about 1 minute. Add ½ cup (32 g) unsweetened cocoa powder, preferably Dutch-process, ⅓ cup vegetable oil, 1 tsp. vanilla bean paste or extract, and ⅓ cup room-temperature water and whisk until cocoa is fully dissolved. Sift ½ cup (58 g) bleached cake flour and ½ tsp. baking powder over, then whisk vigorously to combine.
• Add one fourth of meringue to cocoa mixture and mix thoroughly (you can use either a whisk or rubber spatula). Add remaining meringue in 3 batches, gently folding after each addition until only a few streaks of meringue remain (err on the side of mixing slightly less rather than more to keep the batter billowy).
• Scrape batter into prepared baking sheet and, using a small offset spatula, gently spread to edges of pan, smoothing surface. Bake cake until top springs back when lightly pressed, 18-20 minutes (cake may start to shrink from sides of pan). Let cake cool in pan, 30-40 minutes.
• Using an electric mixer on medium-high speed, beat 2 cups heavy cream, 3 Tbsp. granulated sugar, 2 Tbsp. instant vanilla pudding mix, 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt, and 1 tsp. vanilla bean paste or extract in a large bowl until medium-firm peaks form, about 4 minutes. (Or, use a stand mixer fitted with the whisk attachment, about 1 minute.)
• Run a small offset spatula along edges of pan to release cake from sides. Place a wire rack (same size as cake and rimmed baking sheet) on top of cake and flip over to invert cake onto it; remove baking sheet. Carefully peel away parchment paper (start from a long edge where it might be embedded in the cake and pull gently to ensure you don't tear cake); discard. Place a clean sheet of parchment on top of cake and flip cake over so wire rack is now on top; remove wire rack.
• Dollop filling over surface of cake. Using spatula, smooth cream evenly over cake, working all the way to the edges. Starting from a short end and using parchment as a guide, roll up cake. Transfer cake, seam side down, to a platter and chill until filling is set, at least 30 minutes and up to 4 hours.
• Using a serrated knife, trim ¼"-½" off both ends of cake to create clean edges; discard (or consider them a snack!). Using a small fine-mesh sieve, dust top of Swiss roll with powdered sugar. Slice with serrated knife to serve. Do ahead: Cake (without powdered sugar) can be assembled 2 days ahead. Tightly wrap and keep chilled. Dust with powdered sugar just before serving.
