My kitchen became magical last winter when two of my favorite desserts crashed together. These tiramisu brownies are downright amazing - they mix my super fudgy brownie recipe with a smooth coffee mascarpone on top. I switch between loving the deep espresso brownie bottom and that fluffy cream topping. Each mouthful feels like a treat, and now my friends beg for them whenever they visit.
How These Brownies Will Blow Your Mind
I tweaked this recipe for ages until I got everything just right. The brownies stay incredibly gooey while the mascarpone stays airy and soft. Anyone who loves coffee will flip over the espresso flavor running throughout. I make these when company's coming but they're easy enough to whip up when chocolate cravings kick in.
Must-Have Ingredients
- 70% Bittersweet Chocolate: 8 ounces, melted; grab quality chocolate for the best taste.
- Espresso Powder: 2 teaspoons (try DeLallo brand) to boost the chocolate taste.
- Cocoa Powder: ¼ cup Dutch-process for deeper chocolate flavor. You can use regular cocoa in a pinch.
- Dark Brown Sugar: ½ cup for extra moisture and richness.
- Granulated Sugar: ½ cup to get the sweetness just right.
- Mascarpone Cheese: 8 ounces, softened; creates that genuine tiramisu top layer.
- Heavy Whipping Cream: ½ cup, whipped to make the mascarpone layer fluffy.
- Vanilla Bean Paste: 1 teaspoon for amazing flavor in the creamy layer.
- Unsweetened Cocoa Powder: For sprinkling on top, giving that classic tiramisu look.
Creating Your Dessert Masterpiece
- Create the Espresso Brownie Base
- Heat your oven to 350°F (175°C) and put parchment in an 8x8-inch pan. Melt 8 ounces of bittersweet chocolate and set it aside. Mix ½ cup dark brown sugar, ½ cup granulated sugar, and 2 teaspoons espresso powder in a bowl. Mix in your melted chocolate, 2 eggs, and ¼ cup cocoa powder until everything comes together. Put the batter evenly in your pan and bake about 20-25 minutes until you see small cracks on top.
- Whip Up the Mascarpone Layer
- In another bowl, beat 8 ounces of mascarpone with 1 teaspoon vanilla bean paste and 2 teaspoons espresso powder until it's smooth. Gently mix in ½ cup whipped heavy cream until it gets airy and light.
- Put Everything Together
- Let your brownies cool all the way. Spread your mascarpone mix over the brownies and smooth it out with a spatula.
- Add Cocoa Finishing Touch
- Grab a fine-mesh sieve and sprinkle unsweetened cocoa powder over the mascarpone. This gives you that true tiramisu look.
- Cool and Enjoy
- Stick the brownies in the fridge for at least an hour so the mascarpone firms up. Cut them into squares and enjoy them cold for the best taste.

Insider Baking Tips
Good chocolate really makes these brownies shine, so don't cheap out there. Dutch process cocoa powder works best but the regular stuff is fine too. Keep an eye on them while they bake since you want that crackly top but still want the middle a little soft. I always cool them in the fridge before serving which helps that mascarpone set up just right.
Keeping Them Fresh
You can keep these treats in a sealed container in your fridge for about 4 days but at my place they vanish way faster. If you want to save some, wrap them individually and freeze them for up to 2 months. Just let them thaw in the fridge overnight when you're ready for a treat.
A Showstopping Dessert
I love making these brownies when I'm hosting or friends drop by for coffee. They always become the talk of dinner parties and potlucks. Sometimes I pair them with vanilla ice cream or enjoy one with my afternoon coffee. The mix of chocolate and coffee tastes incredible and I bet you'll want to make batch after batch.
Frequently Asked Questions
- → Can I swap espresso powder for instant coffee?
You can, but use a bit more than the recipe says since instant coffee tastes milder. The result won't be as bold but still delicious.
- → Why pick 70% dark chocolate?
It offsets the sweetness of the cream topping. If using semi-sweet chocolate, cut back on the sugar slightly to keep things balanced.
- → Can I make these bars in advance?
Yep, store them in the fridge for up to 3 days. Just sprinkle cocoa on top right before serving so they stay looking fresh.
- → Why do cracks form on the brownie top?
Cracks happen because eggs and sugar create a thin crust while baking. They’re a good thing—they add nice texture to the bars.
- → Is freezing these an option?
You can freeze the brownie base without the topping for up to 2 months. Top with mascarpone cream after thawing and serve.
