Coffee Layer Cake With Vanilla Espresso Buttercream Recipes

ESPRESSO CHOCOLATE CHIP CAKE

Steps:

• Preheat oven to 350°F (177°C). Grease three 8-inch cake pans, line with parchment paper rounds, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans. (If it's helpful, see this parchment paper rounds for cakes video & post.)
• Whisk the cake flour, baking powder, baking soda, and salt together. Set aside.
• Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter, espresso powder, and sugar together on medium-high speed until combined and creamy, about 2 minutes. Scrape down the sides and up the bottom of the bowl with a rubber spatula as needed. Beat in the egg whites until combined, and then add the sour cream and vanilla extract. Beat until combined. Mixture may look curdled as a result of the varying textures and solid butter combining. Scrape down the sides and up the bottom of the bowl as needed. Pour in the dry ingredients, turn the mixer on low speed and with the mixer running, slowly pour in the milk and coffee. Beat on low speed until combined, and then beat in the chocolate chips just until combined. Whisk it all by hand to make sure there are no butter lumps at the bottom of the bowl. The batter will be slightly thick. Do not overmix.
• Pour batter evenly into cake pans. Bake for around 25-28 minutes or until the cakes are baked through. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean, it's done. Allow cakes to cool in the pans set on a wire rack for 30 minutes. Run a knife around the edges and then remove from pans. Allow cakes to cool completely set on a wire rack. The cakes must be completely cool before frosting and assembling.
• In a large bowl using a hand-held mixer or stand mixer fitted with a whisk or paddle attachment, beat the butter and espresso powder together on medium speed until creamy, about 2 minutes. Add confectioners' sugar, cream/milk, vanilla extract, and salt. Beat on low speed for 30 seconds and then switch to high speed and beat for 2 minutes. Taste and beat in more espresso powder to taste if desired. I usually add another 1/4 teaspoon for more flavor. Yields about 4 cups frosting.
• If your cakes are domed on top, very carefully use a large serrated knife to slice a thin layer off the tops to create a flat surface. Discard (or crumble over ice cream!). Place 1 cake layer on your cake stand, cake turntable, or serving plate. Evenly cover the top with about 3/4 cup frosting. I use and recommend an icing spatula to apply the frosting. Top with 2nd cake layer and spread about 3/4 cup frosting on top. Place 3rd layer on top and frost the sides and top with remaining frosting. A bench scraper is helpful to smooth the sides and feel free to pipe any frosting on top- I used Ateco 849 piping tip to pipe a border around the pictured cake.
• Refrigerate cake for 10-20 minutes before slicing. This helps the cake hold its shape when cutting.
• Cover leftover cake tightly and store in the refrigerator for up to 5 days.

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.)
