Walnut Blackberry Torte With Mocha Buttercream Recipes

Steps:

• Make cake layers:
• Preheat oven to 350°F. Butter a 15- by 10- by 1-inch baking pan and line bottom with wax or parchment paper. Butter paper.
• Pulse walnuts in a food processor until finely chopped (do not allow to become a paste) and stir together with flour in a bowl.
• Beat together butter and 1/3 cup sugar in a large bowl with an electric mixer until pale and fluffy. Add yolks 1 at a time, beating well after each addition, then beat in vanilla. Stir in nut mixture by hand.
• Beat egg whites with salt with cleaned beaters in another bowl at medium speed until they hold soft peaks. Add remaining 1/3 cup sugar and beat at high speed until whites just hold stiff peaks. Stir one fourth of whites into batter to lighten, then fold in remaining whites gently but thoroughly.
• Spread batter evenly in baking pan, smoothing top. Bake in middle of oven until center is set and top is pale golden, 25 to 30 minutes. Cool cake in pan on a rack. Cover cake with an inverted baking sheet, then invert cake onto it and remove paper.
• Reinvert cake onto a cutting board. Trim about 1/4 inch from each side of cake with a sharp knife, then cut cake crosswise into 4 equal rectangles (each about 9 by 3 1/2 inches). Line baking sheet with wax or parchment paper and transfer cake to baking sheet, arranging layers side by side, touching.
• Make jam filling:
• Sprinkle gelatin over water in a small bowl and let stand 1 minute to soften. Heat strained preserves in a double boiler or a metal bowl set over a saucepan of simmering water until warm, then add gelatin mixture and stir until dissolved, about 2 minutes. Remove bowl from heat and set in a larger bowl of ice water. Cool, stirring occasionally, until cold, 5 to 10 minutes.
• Spread jam evenly over cake layers and chill until set, about 1 hour.
• Assemble cake:
• Reserve the nicest-looking cake layer for top. Put 1 cake layer, jam side up, on a cake platter and spread with 1/3 cup buttercream. Top with second cake layer, jam side up, and spread with 1/3 cup buttercream. Top with third layer, jam side up, and spread with 1/3 cup buttercream. Top with reserved cake layer, jam side up. Frost sides of cake with about 1 cup buttercream. Transfer remaining buttercream to pastry bag and pipe a decorative border around top edge of cake.

Steps:

• Make crust:
• Preheat oven to 350°F. Blend ground cookies and coffee powder in processor. Set aside 3/4 cup cookie crumb mixture. Add butter to remaining crumb mixture and process until crumbs are moist. Press mixture onto bottom and up sides of 9-inch-diameter springform pan with 2 3/4-inch-high sides. Bake crust until just firm to touch, about 10 minutes. Cool completely.
• Make fillings:
• Stir chocolate, butter and 1 teaspoon coffee powder in heavy medium saucepan over medium-low heat until melted and smooth. Transfer to large bowl. Set chocolate mixture aside while preparing meringue.
• Stir 1/2 cup sugar and 3 tablespoons water in small saucepan over low heat until sugar dissolves. Increase heat and boil syrup without stirring until candy thermometer registers 240°F, tilting pan to submerge bulb, about 4 minutes.
• Meanwhile, using electric mixer, beat whites in large bowl to soft peaks.
• Gradually beat hot syrup into whites. Continue beating until medium-stiff peaks form, about 3 minutes. Fold 1/3 of meringue into lukewarm chocolate mixture to lighten. Fold in remaining meringue. Set chocolate meringue aside.
• Combine 1/4 cup cream and 5 teaspoons coffee powder in large bowl; stir to dissolve. Add 2 1/2 cups cream, powdered sugar and cinnamon and beat until firm peaks form. Fold 1 1/2 cups coffee whipped cream into chocolate meringue, forming mocha mousse.
• Spoon half of mocha mousse over bottom of crust. Sprinkle 3 tablespoons reserved crumb mixture over mousse. Spoon half of coffee whipped cream over crumbs. Sprinkle with 3 tablespoons crumbs. Repeat layering with remaining mocha mousse, crumbs, coffee whipped cream and crumbs. Cover and refrigerate until set, about 4 hours. (Can be made 2 days ahead; keep refrigerated.) Run knife around pan sides to loosen torte. Remove pan sides and serve.

Steps:

• Place a rack in middle of oven; preheat to 325°. Lightly butter three 8"-diameter cake pans and line bottoms with parchment paper rounds. Toast 2 cups (250 g) raw walnuts in a single layer on a rimmed baking sheet, tossing halfway through, until golden brown, 12-14 minutes. Let cool. Set aside 1 cup walnuts for serving.
• Meanwhile, cook ¾ cup (1½ sticks) unsalted butter in a small saucepan over medium heat, stirring often, until it foams, then browns, 6-8 minutes. Remove from heat and immediately stir in ½ cup plus 2 Tbsp. vegetable oil or refined coconut oil, melted. Set brown butter mixture aside.
• Pulse remaining 1 cup toasted walnuts in a food processor until coarsely ground (it should be the texture of panko). Transfer to a large bowl and whisk in 2 cups (250 g) all-purpose flour, 2¼ tsp. baking powder, 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt, and ½ tsp. baking soda.
• Process 4 large eggs, 1¼ cups (250 g) sugar, 2 tsp. vanilla extract, and 1 tsp. instant espresso powder in food processor (no need to clean bowl) until mixture is lightened in color and thickened, about 30 seconds. Stir 2 Tbsp. whole milk into reserved brown butter mixture. With motor running, gradually stream brown butter mixture into egg mixture and process until combined. Add dry ingredients and process just until a smooth batter forms. Divide batter among prepared pans.
• Bake cakes, rotating pans front to back after 15 minutes, until puffed and just starting to pull away from the sides of pans and a tester inserted in the centers comes out clean, 20-22 minutes. Transfer pans to wire racks and let cakes cool 15 minutes. Run a small knife around edges of each cake to release from pan if needed. Turn out cakes onto racks and remove parchment paper; discard. Turn cakes right side up and let cool completely.
• Combine 8 large egg whites, 2¼ cups (450 g) sugar, ¾ tsp. Diamond Crystal or ½ tsp. Morton kosher salt, and ¼ tsp. cream of tartar in the bowl of a stand mixer. Set over a medium saucepan filled with 1½" of simmering water (bowl should not touch water). Heat, stirring and scraping often with a heatproof rubber spatula, until sugar is dissolved and an instant-read thermometer registers 185°, 10-15 minutes.
• Fit bowl onto stand mixer fitted with whisk attachment and beat, starting on low speed and gradually increasing to high, until meringue is shiny and stiff, 8-10 minutes. Beat in 1 tsp. vanilla extract.
• With mixer on medium speed, add 3 cups (6 sticks) unsalted butter, room temperature, cut into pieces, a piece at a time, mixing until incorporated before adding more. Once all the butter has been added, increase speed to high and beat 1 minute. Transfer buttercream in bowl to refrigerator and chill 30 minutes.
• Fit bowl with buttercream back onto stand mixer and add ¼ cup (21 g) unsweetened cocoa powder, sifted if needed, and 2 tsp. instant espresso powder. Beat on medium-low speed, scraping down sides as needed, until combined.
• Using a large serrated knife and long sawing strokes, remove tops of cakes to level if needed. Place a cake layer, right side up, on a cake stand or large plate. Using an offset spatula, spread ¼ cup buttercream over cake, working all the way to the edges. Place second cake layer, right side up, on top; spread another ¼ cup buttercream over cake, working all the way to the edges. Place third cake layer, cut side down, on top, and press lightly to adhere. Spread top and sides of cake with ½ cup buttercream in a thin, even layer. Chill, uncovered, at least 1 hour and up to 12 hours. (If chilling cake longer than 1 hour, cover remaining buttercream in bowl and chill. Bring to room temperature and beat again before using.)
