This cappuccino cake delivers the rich flavor and cozy aroma of a creamy coffeehouse favorite in every bite. Tender coffee-infused cake layers are paired with a dreamy coffee buttercream and finished with a glossy coffee ganache that makes every slice feel special. Whenever I bake this, my kitchen smells just like my favorite café. I made it as a treat for a friend’s birthday and it was an absolute showstopper on the dessert table.
I first whipped this up for a winter gathering and everyone wanted the recipe by the end of the night. It is the kind of cake people remember long after the last crumb is gone.

Step-by-Step Instructions
- Prepare Cake Pans:
- Spray three six inch round cake pans with baking spray and line the bottoms with parchment paper rounds. This makes sure the cakes release easily and do not stick.
- Mix Dry Ingredients:
- Whisk flour baking powder baking soda and salt together in a bowl. This distributes the leaveners evenly through the cake and prevents clumps.
- Cream Butter and Sugar:
- Beat softened butter and sugar on high with a hand or stand mixer for about four minutes until light and fluffy. This step helps create a cake with a fine tender crumb and is worth the extra mixing time.
- Add Vanilla and Coffee:
- Stir instant coffee granules into vanilla extract until dissolved. Pour this mixture into the creamed butter and sugar along with the eggs. Beat on medium until smooth and scrape the bowl to catch any unmixed bits.
- Combine Wet and Dry Mixtures:
- Add the flour mixture and buttermilk to the butter mixture in alternating additions mixing gently on low then medium just until all is combined and smooth. Scrape the bowl between steps for a uniform batter.
- Bake the Cakes:
- Divide the cake batter between the prepared pans. Bake at three hundred fifty degrees for about thirty minutes until a toothpick comes out clean and the tops spring back when gently pressed.
- Cool and Remove Cakes:
- Let the cakes cool two minutes in the pans then turn out onto a wire rack and cool completely. This keeps the texture soft and prevents the cakes from breaking.
- Prepare the Buttercream:
- Beat softened butter and salt at high speed until pale and fluffy. Gradually add sifted powdered sugar. Dissolve instant coffee into vanilla and beat into the frosting. Whip the frosting again until billowy and light.
- Create the Coffee Ganache:
- Mix heavy cream and instant coffee until dissolved then heat with chopped white chocolate in a double boiler until glossy and melted together. This will be your drip for an impressive finish.
- Crumb Coat the Cake:
- Place the first cake layer on a turntable. Spread a thick layer of coffee buttercream over the top. Add the second and third layers with frosting between each. Smooth a thin layer of frosting over the whole cake and chill for thirty minutes to lock in crumbs.
- Frost the Cake:
- After chilling cover the cake fully with the rest of the frosting using an offset spatula. Smooth the sides and top for a classic polished look and chill again to set the buttercream.
- Add Coffee Ganache Drip:
- Carefully spoon or pipe the coffee ganache around the top edge of the cake so it drips down the sides. Gently spread more ganache on the top for an elegant two tone effect. Chill until set.
- Decorate:
- Pipe decorative swirls of extra buttercream on top and dust with cocoa or add whole espresso beans for a true coffeehouse style finish. Transfer to a serving plate and enjoy with a mug of coffee.

Instant coffee is my favorite touch in this cake because it brings a bold yet smooth coffee note that absolutely shines in both the cake and the buttercream. My family always gathers in the kitchen when they smell this baking and we take turns swirling on the ganache together.
Storage Tips
Once completely cooled and decorated the cappuccino cake stores best when covered and refrigerated for up to five days. Bring to room temperature before serving for the best texture and flavor. Individual slices can be wrapped tightly and frozen for up to two months. When ready to enjoy just thaw in the fridge overnight.
Ingredient Substitutions
If you do not have instant coffee you can use finely ground espresso powder for a more intense taste. No buttermilk on hand Simply mix one cup milk with one tablespoon white vinegar and let sit for five minutes before using. Salted butter works if you omit the added salt from the recipe.
Serving Suggestions
Serve generous slices of cappuccino cake with hot coffee or a vanilla latte for a cozy afternoon treat. The cake pairs beautifully with berries or a dollop of lightly sweetened whipped cream. For celebrations decorate the top with chocolate curls or gold sprinkles for extra flair.
Coffee Cake’s Roots
Coffee flavored cakes are loved in both European and American baking. Inspired by the classic cappuccino this cake blends bold coffee and creamy white chocolate in a classic American layer cake format. My grandmother used to serve a simpler version for Sunday brunches but this version turns it into a decadent dessert for special occasions.
