Gilded Mocha Walnut Layer Cake Recipes

MOCHA WALNUT CAKE WITH MOCHA GLAZE

Steps:

• Preheat oven to 350 degrees. Butter and flour one 8-inch square pan or two 8-inch cake layers. Heat the milk and add coffee granules, stirring until they dissolve. Stir in vanilla and let cool.
• Beat the butter and sugar until fluffy. Beat in the eggs, then the coffee mixture. Combine the flour, salt and baking powder and add to the butter mixture. Stir in walnuts. Spread batter in prepared pan. Bake for 40 to 50 minutes for a square pan, or 30 minutes for round layers. Cool in pan for 5 minutes, then either glaze while still warm, or turn out and cool completely to fill and frost.
• For glaze, combine all the ingredients in a small bowl with a whisk and beat until smooth.

MOCHA-WALNUT MARBLED BUNDT CAKE (DORIE GREENSPAN)

Steps:

• GETTING READY: Center a rack in the oven and preheat the oven to 350°F Butter a 9- to 10-inch (12-cup) Bundt pan, dust the inside with flour and tap out the excess. (If you've got a silicone Bundt pan, there's no need to butter or flour it.) Don't place the pan on a baking sheet - you want the oven's heat to circulate through the Bundt's inner tube.
• Whisk together the flour, ground walnuts, baking powder, and salt.
• Set a heatproof bowl over a saucepan of gently simmering water. Put 2 tbsp of the butter, cut into 4 pieces, into the bowl, along with the chocolate, coffee and instant coffee. Heat the mixture, stirring often, until the butter and chocolate are melted and everything is smooth and creamy - keep the heat low so that the butter and chocolate don't separate. Remove the bowl from the heat.
• Working with a stand mixer, preferably with a paddle attachment or with a hand mixer in a large bowl, beat the remaining 2 sticks of butter and the sugar at medium speed for about 3 minutes - you'll have a thick paste; this won't be light and fluffy. Beat in the eggs one by one, beating well after each addition. The mixture should look smooth and satiny. Beat in the vanilla extract. Reduce the mixer speed to low and add the dry ingredients and the milk alternately, adding the dry mixture in 3 portions and the milk in 2 (begin and end with the dry ingredients).
• Scrape a little less than half of the batter into the bowl with the melted chocolate and, using a rubber spatula, stir to blend thoroughly.
• If you want to go for the gingko pattern, scrape all of the white batter into the pan and top with the chocolate. If you want a more marbled pattern, alternate spoonfuls of light and dark batter in the pan. When all the batter is in the pan, swirl a table knife sparingly through the batters to marble them.
• Bake for 60 to 70 minutes, or until a thin knife inserted deep into the center of the cake comes out clean. Transfer the Bundt pan to a rack and let cool for 10 minutes before unmolding, then cool the cake completely on the rack.

FLUFFY COFFEE AND WALNUT CAKE WITH MOCHA BUTTERCREAM

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.)
