How to Make Mocha Caramel Cake

Step 1: Prepare the Oven and Pans

Preheat oven to 350°F (175°C).

Grease and line two 8-inch round cake pans with parchment paper.

Step 2: Mix Dry Ingredients

In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.

Set aside.

Step 3: Cream Butter and Sugar

In a large mixing bowl, beat softened butter and sugar until light and fluffy (about 3–4 minutes).

Add eggs one at a time, beating well after each.

Mix in vanilla extract.

Step 4: Combine Wet and Dry

In a separate bowl, combine coffee and buttermilk.

Add dry ingredients to the butter mixture in three parts, alternating with the coffee-buttermilk mixture.

Mix gently until just combined.

Step 5: Bake the Cake

Divide batter evenly between the two pans.

Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Cool in pans for 10 minutes, then turn onto wire racks to cool completely.

Step 6: Make the Caramel Buttercream

Beat butter until smooth and creamy (2–3 minutes).

Add powdered sugar gradually and beat until light.

Mix in caramel sauce and a pinch of salt.

Add cream or milk as needed for spreadable consistency.

Beat for another minute until silky and fluffy.

Step 7: Make Salted Caramel Sauce (Optional)

Heat sugar in a saucepan over medium heat, stirring constantly until it melts and turns amber.

Carefully stir in butter.

Slowly add cream (mixture will bubble).

Stir in sea salt and let cool slightly before using.

Step 8: Assemble the Cake

Place one cake layer on a serving plate. Spread with caramel buttercream.

Add second layer and frost the top and sides.

Drizzle with salted caramel sauce and decorate with chocolate shavings or espresso beans.

Chill for 20 minutes before slicing for cleaner cuts.

Chef’s Notes

Use cooled coffee to prevent curdling the batter. Espresso or strong brewed coffee intensifies the chocolate flavor.

For a richer caramel taste, use homemade caramel or a high-quality jarred version.

Make it ahead: Cake layers can be baked and frozen; buttercream can be stored in the fridge for up to 3 days.

No buttermilk? Substitute with milk + 1 tsp vinegar or lemon juice (let sit 5 min).

Want extra height? Use 3 pans for thinner layers and more frosting in between.
