This indulgent chocolate coffee cake brings together deep chocolate richness and aromatic coffee undertones. Each moist layer gets drenched in coffee syrup then wrapped in smooth coffee buttercream, making an irresistible treat that will win over both chocolate and coffee fans.
I came up with this cake after spending years trying to match a special dessert from a tiny family-run Italian cafe. The breakthrough came when I started adding coffee in three different ways, building incredible flavor layers that make this dessert stick in your memory.
Ingredients
- All purpose flour: Delivers the right structure while keeping the cake soft
- Dutch process cocoa powder: Creates richer chocolate flavor compared to regular cocoa
- Instant espresso powder: Boosts coffee taste without making the batter too wet
- Sour cream: Keeps everything moist and gives the cake an amazing soft texture
- Very warm coffee: Wakes up the cocoa powder flavors for stronger chocolate impact
- Chocolate coffee syrup: Keeps the cake juicy while adding another flavor level
- Heavy cream: Makes the frosting super smooth and easy to spread
- Powdered sugar: You can add more or less depending on how sweet you want it
Step-by-Step Instructions
- Prep the Pans:
- Heat your oven to 350°F and get two 8 inch cake pans ready with a light coating of grease and parchment paper circles on the bottoms. The parchment helps your cakes come out perfectly after baking.
- Mix Dry Ingredients:
- Stir the flour, cocoa powder, baking powder, baking soda, espresso powder, and salt together in a big bowl. Break down any cocoa clumps for smooth cake batter. A good stir works fine, but sifting makes it even better.
- Combine Wet Ingredients:
- In another bowl, mix oil, melted butter, both sugars, eggs, sour cream, and milk until everything blends together smoothly. You shouldn't see any egg streaks or sour cream lumps. Using both oil and butter gives you great taste and moisture.
- Create the Batter:
- Add the dry mix to the wet stuff, going back and forth with warm coffee. Start with dry, then coffee, then dry again, then more coffee, finishing with dry. Just stir enough to mix everything - this keeps your cake light and fluffy.
- Bake the Cake:
- Pour equal amounts of batter into your pans and bake for 33 to 38 minutes. Stick a toothpick in the middle - it's done when it comes out with a few crumbs but no wet stuff. Let them sit in the pans for 15 minutes before taking them out to cool completely.
- Make Coffee Syrup:
- While cakes cool down, mix water, coffee, sugar, cocoa powder, and vanilla in a pot. Let it bubble until it gets thicker and can coat a spoon. This syrup adds moisture and pumps up the coffee-chocolate taste.
- Prepare and Soak Cakes:
- Trim any rounded tops off your cakes if needed. Brush each layer with 2 to 3 spoonfuls of the cooled syrup, focusing on the cut areas which soak up liquid better. Pop them in the fridge for 1 to 2 hours to set up.
- Make Coffee Buttercream:
- Whip soft butter until it's smooth, then add vanilla, salt, espresso, and heavy cream. Slowly mix in powdered sugar until you like how thick it is. A final whipping adds air so it spreads well on your cake.
- Assemble the Cake:
- Dab some frosting on your cake plate, add the first layer, spread frosting on top, then add the second layer. Put a thin layer of frosting all over and chill for 20 to 30 minutes. This traps crumbs so your final layer looks clean.
- Final Frosting:
- Spread the rest of your buttercream on the cold cake. For a smooth finish, hold a bench scraper slightly tilted against the side while turning the cake stand. For a more casual look, make swirls with the back of a spoon.

I can't stress enough how important that instant espresso powder is in this recipe. I made this cake once just using brewed coffee without the powder, and wow, what a difference. That concentrated coffee punch really brings out something special in the chocolate - it's what turns this from just another chocolate cake into something you'll crave again and again.
Storage Instructions
Your cake will stay nice and fresh in a sealed container at room temperature for about 3 days. Thanks to that coffee syrup, it stays moist longer than most cakes do. Want to keep it longer? Put it in the fridge for up to a week, but let slices warm up to room temp before eating so you get the best flavor and texture.
Ingredient Substitutions
Don't have Dutch process cocoa? Regular cocoa works too - just add 1/8 teaspoon baking soda to balance it out. Need a dairy-free version? Swap the butter for plant-based butter, use coconut yogurt instead of sour cream, and replace milk with almond or oat milk. The texture will change slightly but it'll still taste fantastic.
Serving Suggestions
This cake tastes amazing with a scoop of coffee or vanilla ice cream for an extra special dessert. For fancy occasions, just dust some cocoa powder on top for a simple elegant look. Coffee lovers will go crazy if you serve it alongside a tiny cup of espresso for the full coffee experience.

This cake stands out as a true showstopper where bold coffee and rich chocolate work together perfectly, bringing joy to everyone who takes a bite.
Recipe Q&A
- → Do I have to use espresso powder?
You don't need to include espresso powder. The brewed coffee in the batter and syrup already gives plenty of flavor, though leaving it out means a gentler coffee taste. For a pure chocolate version, swap in hot water instead of coffee.
- → Can I prep this cake in advance?
Absolutely! The cake layers can be baked 2 days ahead and stored tightly wrapped at room temperature. The syrup keeps in the fridge for 3-4 days. Put everything together and frost the day before for peak freshness. Once done, it stays great in the fridge for up to 3 days.
- → Can I switch Dutch cocoa with regular cocoa?
If you don't have Dutch process cocoa, natural cocoa works too. Just change the leavening mix: lower the baking powder to 1 teaspoon and bump up the baking soda to an equal amount. The texture will be just fine, but the flavor might differ slightly.
- → Why is the syrup so important?
The syrup locks in moisture and kicks up the flavor of chocolate and coffee in each bite. It helps keep the layers tender and fresh, especially if making the cake ahead of time.
- → What's a good sour cream substitute?
Full-fat Greek yogurt works just as well as sour cream in this cake. Even buttermilk can replace it, but you'll want to cut the milk by a quarter cup if you go that route. Each substitute changes the flavor slightly, but the cake will still taste amazing.
- → How do I get creamy buttercream?
Make sure your butter's nicely softened—not melted—before starting. Mix until it's completely smooth, then add other ingredients. Cool the espresso to room temp first. If it's too thick, toss in a bit of heavy cream; if it's runny, add powdered sugar. Whipping at high speed for a couple of minutes makes it super silky.
