Golden Cake With Chocolate Sour Cream Frosting Recipes

Steps:

• Lightly grease a 9-by-13-inch pan with nonstick spray. Heat the oven to 350 degrees.
• Make the cake: In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and sugar on medium speed until light and fluffy, 4 to 5 minutes. Beat in the eggs one at a time, then the egg yolk, scraping the sides of the bowl after each addition. Mix on medium speed until fully incorporated, about 1 minute. Add the vanilla extract and mix to combine, 15 to 30 seconds.
• In a medium bowl, whisk the flour, baking powder, baking soda and salt to combine. Add about 1/3 of the flour mixture to the mixer and mix on low speed until incorporated, about 30 seconds. Add about half the milk and mix on low speed until incorporated, about 15 seconds more. Repeat with another batch of flour mixture, the remaining milk, then the remaining flour mixture until fully incorporated.
• Transfer the batter to the prepared pan and spread in an even layer. Bake until a toothpick inserted into the center comes out clean and the cake is golden and separating from the pan at the edges, 30 to 35 minutes. Cool completely.
• Meanwhile, make the frosting: Add the butter to the bowl of an electric mixer fitted with the paddle attachment and beat on medium speed until light and fluffy, 3 to 4 minutes. Remove the bowl from the electric mixer, and sift the confectioners' sugar and cocoa into the bowl with the butter. Stir with a spatula a few times to incorporate slightly. Return the bowl to the mixer and beat on medium speed until smooth and uniform in color, 1 to 2 minutes. Add the sour cream and melted chocolate and mix on low speed until combined, about 30 seconds. Add the vanilla and salt and mix to combine.
• Spread the frosting on the cooled cake in an even layer. Garnish with sprinkles, if desired.

Steps:

• For the cake: Preheat the oven to 350 degrees F. Position a rack in the center of the oven. Grease the cake pans with 1 tablespoon butter, then dust with 1 tablespoon cocoa powder, tapping out any extra. Set aside.
• In a medium bowl, sift together the flour, baking powder and remaining 1 1/2 cups cocoa powder. Set aside.
• In the bowl of a stand mixer fitted with the paddle attachment, cream the sugar and remaining 3 sticks butter on medium speed until light and fluffy, 5 to 8 minutes. Add the vanilla, then beat in the eggs one at a time. On low speed, add the salt directly to the wet ingredients, then add half of the flour mixture and mix until just combined. Add the sour cream and mix until just combined. Remove the bowl from the mixer and gently incorporate the remaining flour mixture with a rubber spatula. Do not overmix. Fold in the chocolate chips.
• Spread half of the batter in each of the prepared pans. Tap the pans lightly on the counter so that the batter settles. Place the pans on the center rack of the oven and bake until a tester or small knife inserted in the center emerges clean, 40 to 50 minutes. Cool for at least 30 minutes. Unmold onto a rack. Cool to room temperature, 1 1/2 to 2 hours more.
• Mix together the bourbon and the simple syrup in a bowl. Set aside.
• For the frosting: In a medium pot, bring the heavy cream to a simmer. In a medium oven-safe bowl, combine the chocolate and sugar. Place the bowl on top of the pot with the heavy cream to melt. Once the cream is simmering, pour it over the chocolate mixture and stir until all of the chocolate has melted and you have a glossy ganache. Gently stir in the vanilla, followed by the butter pieces. Set aside to let cool to room temperature.
• Transfer the chocolate mixture to the clean bowl of a stand mixer fitted with the whisk attachment. Whip the frosting for 1 to 2 minutes to lighten the texture.
• Put the cake layers on a baking sheet fitted with a wire rack. Using a pastry brush, brush about half the bourbon mixture on each cake layer. Frost the top of the bottom layer, then stack the other layer on top. Frost the top and sides of the cake.
