Ingredients
- 1 3/4 cups all-purpose flour
- 2 cups granulated sugar
- 3/4 cup unsweetened cocoa powder
- 1 1/2 tsp baking soda
- 1 1/2 tsp baking powder
- 1 tsp salt
- 2 large eggs
- 1 cup buttermilk
- 1 cup warm water
- 1/2 cup vegetable oil
- 2 tsp vanilla extract
- 2 tsp instant espresso powder
- 1 cup, softened unsalted butter
- 3 1/2 cups powdered sugar
- 1/2 cup unsweetened cocoa powder
- 2 tbsp heavy cream
Instructions
- Step 1: Preheat oven to 350°F and grease and flour two 9-inch round cake pans; in a large bowl, sift together 1 3/4 cups all-purpose flour, 3/4 cup unsweetened cocoa powder, 2 tsp instant espresso powder, 1 1/2 tsp baking soda, 1 1/2 tsp baking powder, and 1 tsp salt.
- Step 2: In another bowl, whisk 2 large eggs, 1 cup buttermilk, 1 cup warm water, 1/2 cup vegetable oil, and 2 tsp vanilla extract until combined; gradually add the wet ingredients to the dry ingredients, mixing just until smooth.
- Step 3: Divide the batter evenly between the cake pans and bake for 30-35 minutes until a toothpick inserted in the center comes out clean; let cakes cool in pans for 10 minutes, then transfer to wire racks to cool completely.
- Step 4: For the mocha buttercream, beat 1 cup softened unsalted butter on medium speed for 2 minutes until creamy; sift in 3 1/2 cups powdered sugar and 1/2 cup unsweetened cocoa powder, then add 2 tbsp heavy cream and 1 tsp instant espresso powder dissolved in 1 tbsp hot water, beating on low then high until fluffy and spreadable.
- Step 5: Assemble the cake by spreading a thick layer of mocha buttercream on one cake layer, topping with the second layer, then frosting the top and sides evenly; chill for 30 minutes before slicing and serving.
