Ingredients

• 1 cup butter
• 1 tablespoon vanilla extract
• 1 teaspoon salt
• 2 large eggs
• 1 tablespoon instant espresso powder
• 1 (4 ounce) bar dark chocolate, chopped
• 1 cup Dutch-processed unsweetened cocoa powder
• 1.5 cups all-purpose flour
• 0.5 teaspoon baking powder
• 1.5 teaspoons baking soda
• 1.5 cups white sugar
• 0.5 cup mayonnaise
• 1.5 cups stout beer

Recipe Instructions

Step 1

Preheat the oven to 325 degrees F (165 degrees C). Grease three 8-inch round cake pans and line bottoms with parchment paper.

Step 2

Sift flour, cocoa powder, baking soda, salt, and baking powder into a large bowl.

Step 3

Combine stout, vanilla extract, and espresso powder in separate bowl and stir.

Step 4

Beat sugar and butter together in another bowl until creamy, scraping sides occasionally. Add eggs, one at a time, mixing after each addition. Beat in mayonnaise. Alternate adding the flour and stout mixtures, 1/3 at a time, beating after each addition. Fold in dark chocolate just until combined. Split batter between the 3 prepared pans and level out the tops.

Step 5

Bake in the preheated oven until a toothpick inserted into the cakes comes out clean, about 35 minutes. Cool in the pans for 15 minutes, then run a knife around the edge and flip onto a cooling rack. Let cool completely.
