This four-layer Southern classic is made with cocoa powder, not chocolate, with a generous spoonful of mayonnaise in the batter to keep the cake moist and rich. A simple, luscious ganache of semisweet chocolate, cream, and butter does double duty as filling and frosting.
SERVES: 8 t o 1 0
INGREDIENTS:
FOR THE GANACHE
- 1 lb. semisweet chocolate (preferably 58% cacao), finely chopped
- 2 cups heavy cream
- 1 oz. (2 Tbs.) unsalted butter, softened
FOR THE CAKE
- 6 oz. (3/4 cup) unsalted butter, softened; more for the pans
- 8 oz. (1 3/4 cups) unbleached all-purpose flour; more for the pans
- 2 cups packed dark brown sugar
- 2 tsp. pure vanilla extract
- 3 large eggs, at room temperature
- 2 1/4 oz. (3/4 cup) unsweetened Dutch-processed cocoa powder
- 1 1/4 tsp. baking soda
- 1 tsp. baking powder
- 1 tsp. kosher salt
- 1 1/2 cups buttermilk, preferably low-fat, at room temperature
- 1/4 cup mayonnaise
INSTRUCTIONS:
MAKE THE GANACHE
- Put the chopped chocolate in a medium bowl.
- Bring the cream to a boil in a 2-quart saucepan over medium-high heat.
- Pour the hot cream directly over the chocolate and let it sit without stirring for 5 minutes.
- Using a whisk, stir in the center of the mixture in a small, tight circular motion until fully combined.
- Add the butter and stir until it is fully incorporated.
- Put a piece of plastic wrap directly onto the surface of the ganache and set aside at room temperature for at least 8 hours or overnight.
MAKE THE CAKE
- Position a rack in the center of the oven and heat the oven to 350°F.
- Butter two 8×2-inch round cake pans and line each with a parchment round.
- Butter the parchment, dust with flour, and tap out any excess.
- In a stand mixer fitted with the paddle attachment, beat the butter, brown sugar, and vanilla on medium-high speed until lighter in color and slightly increased in volume, 3 to 5 minutes.
- Lower the speed to medium and add the eggs, one at a time, mixing until each is fully incorporated before adding the next.
- Sift the flour, cocoa powder, baking soda, and baking powder onto a piece of parchment. Add the salt to the dry ingredients after sifting.
- Using the parchment as a chute, add one-quarter of the dry ingredients to the batter and mix on low speed until incorporated.
- Add about 1/2 cup of the buttermilk and mix on low speed until incorporated.
- Continue to alternate dry ingredients and buttermilk, mixing until incorporated after each addition and stopping to scrape the bowl and beater as necessary.
- Using a whisk, fold the mayonnaise into the batter.
- Divide the batter evenly between the prepared pans and bake until a toothpick inserted in the center of the cakes comes out clean and the sides of the cake have begun to pull away from the pan slightly, 40 to 45 minutes.
- Remove the pans from the oven and cool on a rack for 15 minutes.
- Invert the cakes onto the rack and remove the pans and parchment.
- Cool the cakes completely. (The cakes may be made 1 day ahead; wrap well and store at room temperature.)
ASSEMBLE THE CAKE
- With a serrated knife, cut each cake in half horizontally.
- Put one of the base layers on a cake plate and tuck strips of waxed paper under the cake to keep the plate clean while icing the cake.
- Top the cake with about 1/3 cup of the ganache, spreading it evenly over the top.
- Add another cake layer, top with ganache, and repeat until the last layer is in place.
- Spread a thin layer of ganache over the top and sides of the cake and refrigerate for 15 minutes to seal in any crumbs.
- Spread the remaining ganache over the top and sides.
- Remove the waxed paper.
- The cake may be refrigerated, covered, for up to 2 days. Return to room temperature 2 hours before serving.
