Ingredients You’ll Need

Most of these ingredients are easy to find at your local grocery store, and you may already have many in your pantry.

Cake:

• 1 dark chocolate cake mix
• 1 cup oil
• 1 cup sour cream
• 1/2 cup milk
• 4 eggs (at room temperature)
• 1 package chocolate pudding mix
• 1 tsp vanilla extract
• 4 tsp instant coffee (Colombian Roast)
• 1 cup mini chocolate chips

Filling:

• 1/2 cup whipping cream
• 1 tbsp instant coffee
• 1/2 cup semisweet chocolate chips
• 6 tbsp butter, room temperature
• 3/4 cup powdered sugar
• 1 tsp vanilla extract

Frosting:

• 1 1/2 sticks butter, softened
• 5-6 cups powdered sugar
• 1tsp vanilla extract
• 1/4 cup milk or cream
• 1/3 cup cocoa powder
• 1/2 cup chocolate chips, melted

Step 1: Prepare the Cake Batter

Start by preheating your oven according to the cake mix instructions. In a large bowl, combine your dry ingredients: the cake mix and pudding mix. In a separate bowl, mix the wet ingredients—oil, sour cream, milk, eggs, and vanilla.

Dissolve the instant coffee in a small amount of hot water or hot coffee to intensify the flavor. This step is key for achieving that signature mocha taste. Add the coffee mixture into your wet ingredients, then combine everything with the dry mixture.

Using an electric mixer with a paddle attachment, beat the batter on medium speed until smooth. Fold in the mini chocolate chips for extra bursts of chocolate in every bite.

Step 2: Bake the Cake Layers

Divide the batter evenly between two greased 8-inch pans. Bake according to package directions or until a toothpick inserted in the center comes out clean.

Once baked, allow the cakes to cool in the pans for about 10 minutes before transferring them to a wire rack. Let them cool completely before assembling—this ensures clean, stable layers.

Step 3: Make the Mocha Filling

In a small glass measuring cup or bowl, heat the whipping cream, instant coffee and chocolate chips, whisking every 30 seconds until smooth and glossy.

Allow the mixture to cool, then beat in the butter, powdered sugar, and vanilla until creamy. Refrigerate until firm but still spreadable. This filling adds a rich, silky texture and enhances the overall coffee flavor of the cake.

Step 4: Prepare the Frosting

In a mixing bowl, beat the softened butter until light and fluffy. Gradually add powdered sugar and cocoa powder, alternating with milk, until you reach your desired consistency. Mix in the vanilla extract and melted warm chocolate  and continue beating until smooth.

This frosting is sweet, buttery, and the perfect complement to the bold flavors of the cake and filling.

Step 5: Assemble the Cake

Place one cake layer on your serving plate. Spread the mocha filling evenly across the top. Add the second layer and gently press down.

Frost the entire cake with the prepared frosting, smoothing the sides and top. For a decorative touch, you can sprinkle crushed espresso beans or chocolate shavings on top.
