3 LAYER BUTTER CAKE RECIPE RECIPES

Steps:

• For the cake: Position an oven rack in the center of the oven, and preheat to 350 degrees F. Butter two 9-inch round cake pans, and line the bottom of each with a round piece of parchment. Sift the flour, baking powder, salt and baking soda together onto a piece of parchment or into a large bowl.
• Beat the butter, brown sugar, peanut butter and granulated sugar in a large bowl with an electric mixer on medium-high speed until the mixture is light and creamy, about 5 minutes. Scrape down the side of the bowl as needed. Add the eggs, 1 at a time, beating well after each addition. Continue beating until the mixture is light and creamy, about 2 minutes. Beat in the vanilla. Reduce the mixer speed to medium-low, and add the flour mixture in 3 additions and the milk in 2 additions, beginning and ending with the flour. Beat until just combined.
• Evenly divide the batter among the prepared cake pans. Bake until a toothpick inserted in the center comes out clean, 30 to 35 minutes. Let the cakes cool in the pans for a few minutes, then transfer them to a cooling rack to cool completely. Invert each onto a cooling rack, and remove the parchment. (The cakes can be stored at room temperature, wrapped in plastic wrap, for 1 day.)
• For the buttercream: Bring a few inches of water to a boil in a saucepan large enough to hold the heatproof bowl of a stand mixer above the water.
• Whisk together the granulated sugar, egg whites and salt in the stand mixer bowl. Set the bowl above the boiling water, and whisk until the mixture is warm to the touch and the sugar has completely dissolved. Transfer the bowl to the stand mixer fitted with the whisk attachment, and beat at medium-high speed until cool and the whites hold stiff peaks, about 5 minutes. Beat in 3/4 cup of the peanut butter until smooth. Beat in a couple of chunks of butter at a time, making sure the pieces are incorporated before adding more. Continue beating on medium-high speed until the buttercream thickens into stiff peaks. (The mixture at some point may appear to be very liquidy, but continue to beat.) Beat in the vanilla.
• To assemble: Slice each cake in half, for a total of 4 cake rounds. Spread the remaining 1/2 cup peanut butter on 3 of the rounds, dividing evenly. Put 1 round, peanut butter-side up, on a cake stand or serving platter, and spread about 3/4 cup of the buttercream on top, leaving about a 1/2-inch border all around. Repeat with 2 more layers of peanut-buttered cake and buttercream. Place the last cake round (without the peanut butter) on top. Frost the outside of the cake with the remaining buttercream. Refrigerate the cake until it sets up (this makes it possible to cut neat slices), at least 4 hours up to overnight. Sprinkle the top with peanut brittle before serving. Serve chilled or at room temperature.

Steps:

• Beat sugar and butter for curd in a bowl with an electric mixer until light and fluffy. Beat in eggs and yolks slowly until well combined. Beat for 1 minute more; stir in lemon juice. The mixture will look curdled; do not panic.
• Pour mixture into a saucepan and cook over low heat until it becomes smooth, about 5 minutes. Increase heat to medium and cook, stirring constantly without letting it boil, until it thickens enough to leave a path on the back of a spoon when you drag a finger through it and reaches 170 degrees F (77 degrees C), about 5 minutes. Remove from heat and stir in lemon zest.
• Let cool to room temperature, 20 to 30 minutes. Press plastic wrap on the surface to prevent a skin from forming and chill in the refrigerator.
• While filling cools, place a rack in the middle of the oven and preheat to 350 degrees F (175 degrees C). Butter and flour two 8- or 9-inch round cake pans.
• Sift cake flour, baking powder, and salt together in a medium bowl. Pulse 1/4 cup sugar and lemon zest together in a food processor until well combined.
• Beat butter and lemon sugar in a large bowl with an electric mixer on medium speed until light and fluffy, about 1 1/2 minutes. Add remaining sugar and beat until smooth, about 1 1/2 minutes. Beat in 1/4 of the milk until just blended. Add flour mixture alternately with remaining milk on low speed in 3 batches, scraping the bowl with a rubber spatula as needed; beat until just blended.
• Beat egg whites in another bowl on medium speed just until foamy. Add cream of tartar. Increase speed to medium-high and beat until stiff peaks form. Add 1/4 of the egg whites to the cake batter and gently fold in. Continue to gently fold in egg whites, being careful not to deflate the mixture. Divide batter between the prepared pans.
• Bake in the preheated oven until a toothpick inserted into the center of each cake layer comes out clean, 35 to 40 minutes. Flip right side-up and let cool on a wire rack, 30 minutes to 1 hour.
• Cut cooled layers in half and layer with curd.
• Beat butter and lemon zest for frosting in a medium bowl until light and fluffy. Add confectioners' sugar and beat. Add lemon juice and beat for 1 minute. Frost the assembled cake as desired.
