Why I Love This Recipe

As a food writer, I’m always drawn to desserts that feel indulgent but balanced. This cake delivers:

• Deep chocolate flavor enhanced by coffee
• Ultra-moist crumb thanks to buttermilk
• Silky, not-too-sweet espresso buttercream
• Fresh blackberries for brightness

The coffee doesn’t overpower—it simply intensifies the chocolate, creating layers of complexity in every bite.

Ingredients

For the Chocolate Mocha Cake

• 2 cups all-purpose flour
• 1 3/4 cups granulated sugar
• 3/4 cup unsweetened cocoa powder
• 2 teaspoons baking powder
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1 cup buttermilk
• 1/2 cup vegetable oil
• 3 large eggs
• 2 teaspoons vanilla extract
• 1 cup strong brewed coffee, cooled

For the Coffee Buttercream

• 1 cup unsalted butter, softened
• 4 cups powdered sugar
• 2 tablespoons instant espresso powder dissolved in 2 tablespoons hot water
• 2 tablespoons heavy cream
• 1 teaspoon vanilla extract
• Pinch of salt

For Garnish

• Fresh blackberries
• Chocolate shavings or cocoa powder

Ingredient Swaps & Notes

• Extra bold flavor: Add a teaspoon of espresso powder directly into the cake batter.
• No buttermilk? Use milk with 1 tablespoon lemon juice or vinegar.
• Dark chocolate version: Use Dutch-processed cocoa for deeper flavor.
• Berry swap: Raspberries pair beautifully with mocha as well.

Let coffee cool before adding to the batter to avoid scrambling the eggs.

Step-by-Step Instructions

1. Prepare the Pans

Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans.

2. Mix Dry Ingredients

Whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.

3. Add Wet Ingredients

Add buttermilk, oil, eggs, and vanilla. Mix until combined. Slowly stir in cooled coffee until batter is smooth.

4. Bake

Divide batter evenly among pans. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Cool completely.

5. Make the Buttercream

Beat softened butter until creamy. Gradually add powdered sugar.

Mix in dissolved espresso, vanilla, heavy cream, and salt. Beat until light and fluffy.

6. Assemble

Place one cake layer on a serving plate and spread with buttercream. Repeat with remaining layers.

Apply a thin crumb coat and chill briefly. Finish with a smooth final layer of frosting.

7. Decorate

Top with buttercream swirls, fresh blackberries, and chocolate shavings or a dusting of cocoa powder.

Tips for Success

• Use room-temperature ingredients for even mixing.
