I just combined my two favorite desserts… and I’m never looking back. Brownies have always had my heart—I’m a certified chocoholic through and through. But tiramisu? That’s my go-to restaurant dessert. It’s creamy, bold, sweet, and a little sultry, and it never misses. So naturally, I thought, why not mash up both? These brown butter tiramisu brownies are rich, fudgy, and full of bold espresso flavor, with a mascarpone whipped topping that’s honestly good enough to eat with a spoon. I’m on a huge tiramisu kick lately, so don’t be surprised if a full tiramisu recipe week is coming soon.
Ingredients:
Unsalted Butter – Browning the butter brings a rich, nutty, toffee-like flavor that deepens the taste of the chocolate and adds complexity to the base. It’s a small step with major payoff.
Light Brown Sugar – Adds moisture and chewiness, and the molasses gives the brownies a deeper caramel undertone.
Granulated Sugar – Balances the brown sugar and contributes to the crackly top we all love on a good brownie.
Eggs – These bind everything together, but they also help create that fudgy, dense texture. Room temp is key for even mixing.
Vanilla Extract – Rounds out the flavors and adds warmth. It’s subtle but noticeable.
Dutch-Processed Cocoa Powder – This is non-acidic, smooth, and deeply chocolatey. It makes the brownies rich and decadent. Sift it!
Fine Grain Salt – Brings balance and sharpens the sweetness. Just a pinch is all you need.
All-Purpose Flour – Minimal flour keeps these brownies dense and fudgy. Sift it to avoid dry clumps.
Ladyfingers – Classic tiramisu component. They soak up all the coffee flavor and become soft and cake-like.
Espresso or Coffee – Adds depth and boldness. The caffeine boost is just a perk.
Coffee Liqueur – Optional, but enhances that signature tiramisu flavor. Boozy, bittersweet, and delicious.
Mascarpone Cheese – Essential for the whipped topping. It’s rich, creamy, and slightly tangy.
Heavy Cream – Whips into a light, fluffy texture to mix with mascarpone and balance its richness.
Powdered Sugar – Sweetens the mascarpone layer and helps with structure.
Cocoa Powder (for dusting) – Adds a bitter-sweet finish and classic tiramisu flair.

What Is Tiramisu?
Tiramisu is a traditional Italian dessert made of espresso-soaked ladyfingers layered with a whipped mixture of mascarpone cheese, eggs (or whipped cream), and sugar. It’s rich, bold, creamy, and has a slight bitterness from cocoa powder and coffee. It literally means “pick me up,” which is fitting considering the espresso kick.
Equipment Needed for my Brown Butter Tiramisu Brownies:
-
9×9 inch baking pan – This size ensures thick, fudgy brownies with even baking and perfect layering.
-
Saucepan (for browning butter) – A light-colored saucepan lets you watch the butter closely as it browns so you don’t burn it.
-
Stand mixer or hand mixer – You’ll need the power to whip the mascarpone and cream into a light, fluffy topping.
-
Mixing bowls – Multiple bowls help keep your steps organized—from browning butter to mixing batter to whipping topping.
-
Sifter or fine mesh strainer – Sifting the cocoa and flour prevents lumps and creates a smooth, even batter.
-
Spatula – Perfect for scraping every bit of batter and spreading layers evenly without overmixing.
-
Measuring cups + spoons – Accuracy matters in baking—especially with ratios like butter, flour, and sugar.
Substitutions & Modifications
-
No espresso? Use strong brewed coffee or instant espresso dissolved in water.
-
No mascarpone? Try full-fat cream cheese, though it’ll be slightly tangier.
-
Want it alcohol-free? Omit the coffee liqueur or use a splash of vanilla.
-
Don’t have Dutch cocoa? Use regular unsweetened cocoa powder, but the flavor will be slightly less intense.
