Velvety chocolate cake soaked with bold coffee and crowned with fluffy mascarpone topping delivers a mouth-watering treat without fancy tricks. This smart blend brings together Italy's famous tiramisu and everyone's favorite chocolate cake. You'll love how the damp, coffee-infused base plays against the soft, light mascarpone layer with each taste, making it perfect for regular family meals or fancy get-togethers.
I whipped up this cake for a dinner with friends when I needed something wow-worthy but didn't want to spend all day baking. Folks were asking me for the recipe before they even left, and my sweet-avoiding neighbor actually went back for seconds. The magic happens when coffee turns basic chocolate cake into something special while the creamy mascarpone adds just the right smooth touch on top of the rich bottom layer.
Premium Components
- All-purpose flour: Gives just the right body without making the cake tough.
- Dutch-processed cocoa powder: Makes the chocolate taste richer and look darker.
- Granulated sugar: Cuts through the bite of cocoa and coffee.
- Buttermilk: Adds a nice zing while keeping everything soft.
- Neutral oil: Keeps your cake juicy even after cooling in the fridge.
- Large egg: Helps hold everything together and adds richness to the base.
- Vanilla extract: Makes both chocolate and coffee taste even better.
- Instant coffee: Boosts the chocolate flavor in your cake mix.
- Strong brewed coffee: Gives you that classic tiramisu soaking element.
- Heavy cream: Creates the base for your soft, fluffy topping.
- Mascarpone cheese: Brings that real tiramisu taste and smooth, fancy feel.
Cooking Steps
- Oven Preparation:
- Heat your oven to 350°F and get a nine-inch square pan ready by greasing it well and putting in parchment paper with extra hanging out on two sides so you can lift the cake out easily after baking.
- Dry Ingredient Combination:
- Mix your sifted flour, cocoa powder, sugar, salt, and baking powder in a big bowl until they're well blended with no little cocoa clumps left.
- Wet Component Integration:
- Pour in buttermilk, oil, egg, and vanilla to your dry stuff, then stir gently just until mixed - don't go crazy or you'll make the cake tough by working up the gluten.
- Coffee Enhancement:
- Melt instant coffee in hot water in a small dish, mix until it's gone, then pour it into your batter and fold gently until everything looks the same color.
- Baking Time:
- Pour your mix into the pan, smooth the top with a spatula, then bake about twenty-five to thirty minutes until you can stick a toothpick in and it comes out with just a few damp crumbs.
- Cooling Period:
- Let your cake sit in the pan for fifteen minutes before using the paper edges to pull it out onto a wire rack to finish cooling, which helps it get the right texture.
- Cream Preparation:
- In a cold bowl, beat cold heavy cream with sugar and vanilla until soft peaks show up, then carefully fold in cool mascarpone cheese twice until it's smooth but not over-mixed.
- Assembly Technique:
- Once your cake is totally cool, cut off any rounded top if needed for a flat surface, then brush plenty of strong coffee all over the top until it's good and damp but not soggy.

My Italian grandma showed me how to make real tiramisu years ago, and she was super picky about exactly how to layer the ladyfingers and how strong the coffee should be. When I made this cake version the first time, I thought she'd call it fake tiramisu. But surprise - she actually wanted the recipe! She liked how the cake soaked up coffee more evenly than ladyfingers do, so every bite had the same yummy flavor.
Tasty Presentation
Slice into big squares with a warm, clean knife, wiping it off between cuts for nice clean edges that show off the layers. Don't serve it too cold - let it sit out about ten minutes to bring out all the flavors. Try adding fresh berries on the side to brighten up the rich, creamy dessert or sprinkle extra chocolate shavings on top for serious chocolate lovers.
Fun Twists
Make it grown-up by adding two tablespoons of Kahlúa, Baileys, or Amaretto to the coffee soak for special occasions. Try mixing orange zest into the mascarpone topping for a fresh citrus kick that goes great with both chocolate and coffee. You can also try putting thin slices of fresh strawberries between the cake and cream for a spring version that adds nice color and fruity contrast.
Keeping It Fresh
Keep your finished cake covered in the fridge for best results, where it'll stay good for up to five days though it tastes best in the first three. If you want to freeze some, wrap single slices tightly in plastic wrap then foil, and thaw them overnight in the fridge before eating. Always save the cocoa powder dusting for right before serving since it gets damp during storage and won't look as pretty.

This tiramisu chocolate cake has become my go-to dessert when I want to bring something everybody loves but still feels special. What amazes me most about this recipe is how it takes simple stuff and turns it into something that tastes way fancier than you'd expect. Letting it sit overnight works wonders as the coffee sinks into the cake and the mascarpone topping sets just right, making it perfect for busy hosts who don't want to fuss at the last minute but still want to wow their guests.
Frequently Asked Questions
- → Can I prepare this in advance?
- Definitely! It’s actually better after chilling for 6 hours or overnight. You can make it 1-2 days before and keep it in the fridge.
- → What works instead of mascarpone?
- If mascarpone isn’t available, mix 8 oz cream cheese with 1/4 cup heavy cream and 2 tablespoons sour cream. It won’t taste identical but will still be tasty.
- → Is espresso powder okay to use?
- Yes! Espresso powder gives a stronger coffee kick that works perfectly. Measure it the same as instant coffee.
- → Why is my mascarpone cream grainy?
- This can happen if the mascarpone is too cold or overmixed. Let it warm slightly before whipping and stop as soon as the texture turns smooth.
- → Can I bake this in another pan size?
- Sure! Use an 8-inch square for a thicker cake layer or a 9-inch round. Check for doneness with a toothpick as baking time may vary slightly.
