Two iconic desserts collide in the most delicious way possible. These tiramisu brownies bring together a dense, fudgy chocolate base with espresso-kissed lady fingers and a cloud-like mascarpone topping — everything you love about both desserts in every single bite.

What are tiramisu brownies?
If you’ve never thought about combining tiramisu and brownies before, prepare to have your world changed. This recipe was born out of pure dessert obsession, and honestly, it makes complete sense when you think about it — chocolate, coffee, and cream are basically best friends.
These brownies are built in three distinct layers, each one pulling its weight:
1. The fudgy brownie base: We’re talking deeply chocolatey, borderline gooey brownies with a whisper of espresso powder folded in. The coffee doesn’t scream at you here — it just quietly makes everything taste more like chocolate, which is exactly what you want.
2. Coffee-soaked lady fingers: The bridge between brownie and cream, these little guys soak up just enough coffee to stay tender without turning soggy. They also leak a little coffee into the top of the brownie, making it even more moist and fudgy. Win-win.
3. Whipped mascarpone cream: Four ingredients, zero fuss. This topping is silky, airy, and holds a clean edge when sliced. Think mousse-like, but sturdier. A final dusting of cocoa powder ties the whole thing together.
How To Make The Fudgy Brownie Bottom
The brownie layer is straightforward and comes together quickly. Here’s how it goes:
1. Melt the butter and stir in chocolate and coffee. Heat the butter until it just starts to sizzle, then pull it off the heat and add in the chopped chocolate and espresso powder. The residual warmth will melt everything smoothly. If a few stubborn chocolate pieces remain, a quick return to low heat will take care of them.
2. Pour the hot butter mixture over the sugar. Do this while everything is still warm — it helps dissolve the sugar and cools the mixture down quickly. It’ll look grainy and a bit rough at this stage, and that’s completely fine.
3. Add the eggs one at a time. Room-temperature eggs are non-negotiable here. Cold eggs can cause the batter to seize up, and nobody wants that.
4. Stir in the remaining ingredients. Vanilla, oil, cocoa powder, salt, and finally flour. Once the flour is incorporated, the batter is ready to bake.
5. Bake, then cool completely. This part is important — the brownie needs to reach full room temperature before you add anything on top. A warm brownie will melt the mascarpone and turn everything into a mess.
Making The Tiramisu Layers
The tiramisu twist in these brownies comes from coffee-soaked ladyfingers and a light, creamy mascarpone topping layered over the cooled brownie base. Here’s how to bring it all together:
1. Make the coffee soak: Dissolve the instant coffee and sugar in boiling water, then let it cool completely to room temperature before using. Don’t skip this step—if the coffee is still warm, the ladyfingers will absorb too much liquid and become soft and mushy.
2. Dip the ladyfingers: Working one at a time, quickly dip each ladyfinger into the cooled coffee for about 1 second, then arrange them in a single layer over the brownies. A quick dip is all they need to soak up the coffee without falling apart.
3. Prepare the mascarpone filling: In a large bowl, beat the mascarpone cheese, powdered sugar, and vanilla extract until the mixture is smooth, creamy, and free of lumps.
4. Add the heavy cream: Slowly pour in the heavy cream while mixing on low speed. Adding it gradually helps keep the mixture silky and prevents it from curdling. Once all the cream is incorporated, increase the speed and whip until stiff peaks form.
5. Assemble and chill: Spread the mascarpone cream evenly over the ladyfinger layer. Refrigerate the brownies for at least 1 hour so the layers can set. Just before serving, finish with a generous dusting of cocoa powder, then slice and enjoy.
Baking Brownies
Over- or under-baked brownies can ruin the whole thing, so pay attention here. The surface should look set and slightly crackled — not wet or glossy. When you insert a skewer into the center, it should come out with a few moist, fudgy crumbs clinging to it. A clean skewer means overbaked. A streak of wet batter means it needs more time. Fudgy crumbs? That’s your green light.
How to Slice Tiramisu Brownies
Cold brownies, sharp knife — that’s the secret. Make sure the topping has fully firmed up in the fridge before you even think about cutting. Press the knife straight down through all the layers, then slide it out sideways. Wipe the blade clean between every single cut.
If the brownie keeps sticking to the knife, run the blade under hot tap water, wipe it dry, and try again. If the brownies have been in the fridge for a long stretch and feel too firm, let them sit out for five to ten minutes before cutting.
Serving Tiramisu Brownies
Because of the cheese topping, these brownies should be kept in the fridge and served relatively cold. If you find the brownie has firmed up more than you like as it sits in the fridge, you can set it out at room temperature for about 15 to 20 minutes or until it’s softened up slightly before serving. But I do recommend slicing the brownies while they’re cold and then let them warm up to your liking – it’s just much easier to get clean cuts when they’re cold.
Just like with classic tiramisu, these brownies are best served within no more than 4 days. The ladyfingers do continue to soften as they sit and they can get overly soft if left for longer than that.
Tiramisu Brownies
Ingredients
For the espresso brownie bottom:
- ½ cup 115g unsalted butter
- 6 oz 170g semi-sweet chocolate, chopped
- 1 tablespoon espresso powder
- 1 ¼ cups 250g granulated sugar
- 3 large eggs at room temperature
- 1 teaspoon pure vanilla extract
- 3 tablespoons vegetable oil
- ½ cup 40g unsweetened cocoa powder
- ¼ teaspoon salt
- ½ cup 65g all-purpose flour, spooned and leveled
For the coffee soaked lady fingers:
- ⅔ cup 160mL boiling water
- 1 tablespoon espresso powder
- 1 tablespoon granulated sugar
- 12 Savoiardi lady fingers
For the mascarpone cream topping:
- 8 oz 225g cold mascarpone cheese*
- ⅓ cup 45g powdered sugar
- 1 teaspoon pure vanilla extract
- 1 cup 240mL cold heavy whipping cream
- cocoa powder for dusting on top
Instructions
Make the espresso brownie:
- Start by preheating your oven to 350°F. Grease an 8×8-inch baking pan with butter, then line it with parchment paper, leaving a little overhang on the sides. That extra parchment makes lifting the brownies out later much easier.
- In a medium saucepan, melt ½ cup (115g) unsalted butter over medium heat. Let it cook just until it’s fully melted and beginning to gently sizzle.
- Remove the pan from the heat and immediately whisk in 6 oz (170g) semi-sweet chocolate and 1 tablespoon espresso powder. Keep whisking until the mixture is smooth and glossy.
- Pour the warm chocolate mixture into a large bowl and add 1¼ cups (250g) granulated sugar. Whisk until combined. The batter may look a little grainy at this stage, and that’s perfectly normal.
- Add the 3 eggs one at a time, whisking well after each addition. Once the eggs are fully incorporated, stir in 1 teaspoon vanilla extract, 3 tablespoons vegetable oil, ½ cup (40g) cocoa powder, and ¼ teaspoon salt.
- Lastly, add ½ cup (65g) all-purpose flour and mix just until no streaks of flour remain. Be careful not to overmix, as that can make the brownies less tender.
- Spread the batter evenly into the prepared pan and bake for 27–32 minutes. The brownies are ready when the top no longer looks wet and a skewer inserted in the center comes out with a few moist, fudgy crumbs but no raw batter.
- Let the brownies cool completely in the pan before adding the tiramisu layers on top. This helps everything set properly and keeps the layers neat and stable.
Make the lady finger layer:
- In a wide, shallow bowl, stir together the boiling water, espresso powder, and granulated sugar until everything has fully dissolved. Set the coffee mixture aside and let it cool completely to room temperature.
- Once the coffee has cooled, quickly dip each ladyfinger into the coffee—just a quick one-second dunk is all they need. Arrange them in a single layer over the cooled brownie, trimming a few if needed to fit. Be careful not to soak them too long, or they’ll become too soft and soggy.
- Set the brownie aside while you prepare the creamy topping.
Make the mascarpone cream topping:
- In a large mixing bowl, add the cold mascarpone, powdered sugar, and vanilla extract. Using a hand mixer or a stand mixer fitted with the paddle attachment, beat everything together until the mixture is smooth and creamy.
- Keep the mixer on low speed and slowly pour in the cold heavy whipping cream a little at a time. Adding it gradually helps keep the mixture smooth and prevents it from becoming lumpy. Stop after every ¼ cup of cream to scrape down the sides and bottom of the bowl so everything mixes evenly. If it’s easier, add just 1 to 2 tablespoons of cream at a time, mixing well before adding more.
- Once all of the cream has been incorporated, increase the mixer speed to high and whip for 1 to 2 minutes, or until the mascarpone cream becomes thick, fluffy, and holds stiff peaks.
- Spoon the whipped mascarpone cream over the brownie (or ladyfingers) and gently spread it into an even layer.
- Refrigerate for at least 1 hour, or until the mascarpone topping is chilled and set.
- When you’re ready to serve, use the parchment paper overhang to lift the brownie out of the pan and transfer it to a cutting board. Finish with a generous dusting of cocoa powder, then slice and enjoy.
Notes
- Room temperature eggs are essential for the brownie batter — cold eggs can cause the mixture to seize or turn lumpy.
- Don’t rush the cooling steps. Both the brownie and the coffee soak must be at room temperature before assembling, or the layers won’t set properly.
- Dip the lady fingers fast — a 1-second dip is all they need. Too long and they’ll become soggy and fall apart.
- These brownies are best enjoyed within 4 days. Store covered in the refrigerator.
- For the cleanest slices, cut while cold, then let individual pieces sit at room temperature for 10–15 minutes before serving if you prefer a softer texture.
- If the brownies seem too firm straight from the fridge, rest them at room temperature for 5–10 minutes before cutting.
