Gilded Mocha Walnut Layer Cake Recipes

WALNUT MOCHA TORTE

Steps:

• Separate the eggs: Separate the eggs, into yolks and whites (see How to Separate Eggs ). Take care to make sure there are no pieces of shell or egg yolk in the whites, and that the bowl you are using to contain them is completely clean with no residue of fat. Any fat from yolks or oil will make it difficult to beat the egg whites.
• Prepare cake pans: Prepare two 9-inch cake pans. Line the pans with parchment paper or wax paper. Lightly butter the sides of the pans (not the paper).
• Preheat oven to 350°F (175°C)
• Mix ground walnuts and breadcrumbs: Mix together the ground walnuts and the bread crumbs in a small bowl and set aside.

DORIE GREENSPAN'S MOCHA WALNUT TORTE

Steps:

• Place a rack in the center of the oven and preheat it to 350°F (180°C).
• Coat a 9-inch (23 cm) springform pan with butter or baking spray. Line the bottom with parchment and butter or spray the parchment, then dust the pan with cocoa powder. Place the pan on a rimmed baking sheet lined with parchment or a silicone baking mat.
• In a food processor, combine the nuts, 2 tablespoons (25 g) of the sugar, the chocolate, coffee, and cinnamon and pulse, scraping the sides and bottom of the bowl often and taking care that you don't process for so long that the walnuts become a paste and the chocolate melts. You want to end up with a bread-crumb-like mixture-it's better to have some discernible morsels than to overdo it.
• Separate the eggs, putting the yolks in a large bowl and the whites in the bowl of a stand mixer or a large bowl that you can use with a hand mixer.
• Working with a whisk, beat the yolks until they're homogeneous. Gradually whisk in 3/4 cup (150 g) of the sugar and then beat until the mixture is pale and your whisk leaves tracks, about 2 minutes.
• Beat in the vanilla. Switch to a flexible spatula and stir in the walnut mixture.
• Add the salt to the whites. Attach the bowl to the mixer stand, if using, and fit it with the whisk attachment. Beat the whites until they are foamy, opaque and just a bit thick, 1 to 2 minutes.
• Beat in the remaining 1/4 cup (50 g) sugar, adding it a tablespoon at a time. Once all the sugar is in, the whites should be thick and glossy-lift the beater(s), and the meringue should hold a pretty peak. If it doesn't, continue to beat for 2 to 3 minutes more.
• Using a flexible spatula, scoop out about a quarter of the meringue and add it to the bowl with the egg yolk mixture. Stir everything together energetically so that the whites lighten the thick mixture.
• Scrape the rest of the meringue into the bowl and, being gentle, stir and fold it in. (Without overdoing it, you want to get as much of the meringue into the nut mixture as quickly as possible. If there are a few white streaks, it's fine (better to have streaks than to knock all the air out of the meringue.) Scrape the batter into the pan, swiveling the pan from side to side to settle the batter evenly.
• Bake until the cake feels firm to the touch and has risen and a tester inserted into the center of the cake comes out clean, 40 to 50 minutes. (The rise might be higher around the edges, but the middle should lift too.)
• Move the pan to a rack and let rest for 5 to 10 minutes, then run a table knife between the cake and the sides of the pan to release the cake. Remove the sides of the springform and allow the cake to cool to room temperature on the rack.
• Rinse a small saucepan with cold water, but don't dry it (this helps prevent the cream from scorching). Pour in the cream, set the pan over medium heat and bring just to a boil.
• Remove from the heat and add the chocolate. Wait 30 seconds and then, working with a small flexible spatula and beginning in the center of the pan, start stirring the chocolate and cream together. Stir in ever-widening concentric circles until you have a thick, shiny, smooth mixture. Piece by piece, blend in the butter until melted and smooth, about 3 minutes.
• When the cake is cool, invert it, remove the base of the pan and the parchment and turn the cake right side up onto the rack.
• If you want to glaze the cake, now's the time. Put a piece of foil or other drip catcher under the rack, pour the ganache over the cake and use an offset spatula or knife to smooth it over the top. (Alternatively, you can drizzle the ganache over the cake. And if you're using toasted walnuts, sprinkle them over the glaze while it's still warm.)
• Refrigerate the cake until chilled, wrapping it well once it's cold. The cake is good at room temperature, but I prefer it straight from the fridge. It also cuts better when it's cold.
• Serve with whipped cream or crème fraîche or, if you prefer, dust the top with confectioners' sugar. Or don't-it's fine just the way it is.

MOCHA LAYER CAKE WITH CHOCOLATE-RUM CREAM FILLING

Steps:

• For filling and topping:
• Stir first 3 ingredients in heavy large saucepan over medium-high heat until sugar dissolves and cream comes to simmer. Remove from heat. Add 20 ounces chocolate; whisk until melted and smooth. Whisk in rum and vanilla. Transfer 1 cup warm chocolate mixture to small bowl; whisk remaining 2 ounces chocolate into mixture in bowl and set aside for topping. Cover; let stand at room temperature. Transfer remaining chocolate mixture to large bowl to use as filling; chill until cold and thick, at least 6 hours and up to 1 day.
• For syrup:
• Stir water and sugar in small saucepan over low heat just until sugar dissolves. Remove from heat; mix in rum. Cover and let stand up to 1 day.
• For cake:
• Preheat oven to 350°F. Butter 9x9x2-inch metal baking pan. Line bottom with waxed paper; butter paper. Combine vanilla and coffee powder in cup; swirl to dissolve coffee. Sift flour, cocoa, and baking soda into small bowl. Using electric mixer, beat egg yolks and 1/2 cup sugar in medium bowl until very thick and light in color, about 3 minutes. Beat in vanilla-coffee mixture. Using clean dry beaters, beat egg whites, cream of tartar, and salt in large bowl until soft peaks form. Gradually add remaining 1/4 cup sugar, beating until stiff but not dry. Fold 1/3 of whites into yolk mixture. Fold in half of flour mixture. Fold in half of remaining whites, then remaining flour mixture, then remaining whites. Transfer batter to prepared pan; gently spread to even thickness.
• Bake cake until puffed and tester inserted into center comes out clean, about 18 minutes. Cool in pan on rack (cake may shrink slightly).
• Cut around pan to loosen cake. Turn out onto work surface; peel off paper. Using long serrated knife, cut cake horizontally in half. Place 1 half, cut side up, on platter. Drizzle half of syrup (about 3 1/2 tablespoons) over. Using electric mixer, beat cold chocolate filling until thick and lighter in color, less than 1 minute. Spread all of filling evenly over cake layer, aligning with sides of cake (filling will be about 1 inch thick). Drizzle remaining syrup over cut side of second cake layer. Place layer, syrup side down, atop filling; press to adhere. Rewarm topping over low heat just until pourable. Pour topping onto top center of cake. Using small spatula, spread topping to edges, being careful to keep it from spilling over. Chill cake up to 1 day, covering loosely with foil or with cake dome after 2 hours.
• Cut cake into 16 squares and serve.

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.)
