Tiramisu Brownies combine a dense, fudgy chocolate brownie with espresso flavor, a light mascarpone cream topping, and a dusting of unsweetened cocoa powder. The dark chocolate base keeps the dessert rich, while the cool, tangy topping adds the creamy contrast associated with classic tiramisu.
These layered brownies are baked in a 9-inch square pan, cooled completely, and chilled after topping. Plan for at least 2 1/2 hours of cooling and chilling so the mascarpone layer can firm enough for clean slices.

How to Make Tiramisu Brownies with Mascarpone Cream
Prepare the Oven and Pan
Preheat the oven to 350°F (175°C). Lightly grease a 9-inch (23 cm) square metal baking pan. Line it with parchment paper, leaving an overhang on two sides to help lift out the brownies.
Melt the Butter and Chocolate
Place the butter and chopped semisweet chocolate in a medium heatproof bowl. Microwave in 20-second intervals, stirring after each interval, until almost completely melted. Stir until smooth and glossy. Let the mixture cool for about 5 minutes so it is warm rather than hot.
Dissolve the Espresso
Stir the espresso powder and hot water together in a small bowl until no dry granules remain. Set aside briefly.
Whisk the Sugars and Eggs
In a large mixing bowl, whisk the granulated sugar, brown sugar, and eggs for 1 to 2 minutes. The mixture should look smooth, slightly thickened, and lighter in color.
Add the Chocolate Mixture
Whisk the melted chocolate mixture, dissolved espresso, and vanilla into the eggs. Continue whisking until the batter is uniformly dark and glossy.
Combine the Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, and salt. Break up any visible lumps of cocoa powder.
Finish the Brownie Batter
Add the dry ingredients to the chocolate mixture. Fold gently with a flexible spatula just until no streaks of flour remain. The batter should be thick, glossy, and slowly spread when pushed with the spatula. Do not continue mixing once the dry ingredients are incorporated.
Fill the Pan
Scrape the batter into the prepared pan and spread it evenly into the corners. Smooth the top with the spatula so the brownie layer bakes at an even thickness.
Bake the Brownies
Bake on the center rack for 30 to 35 minutes. The edges should look set and slightly raised, while the center should no longer appear wet. A toothpick inserted about 1 inch from the edge should come out with moist crumbs but no liquid batter.
Cool Completely
Place the pan on a wire rack and let the brownies cool for 30 minutes. Use the parchment overhang to lift them from the pan, then place them on the rack and cool for another 1 hour. The surface must feel completely cool before the topping is added.
Begin the Mascarpone Cream
Place the cold mascarpone, powdered sugar, and vanilla in a large mixing bowl. Beat on low speed for about 20 seconds, just until combined and smooth. Avoid prolonged mixing because mascarpone can become grainy if overworked.
Whip the Topping
With the mixer running on low, gradually pour in the cold heavy cream. Increase to medium speed and whip for 1 to 3 minutes, until the mixture forms medium peaks. The cream should hold its shape when the beaters are lifted but still look smooth and spreadable. Stop immediately if it begins to look stiff or grainy.
Top the Brownies
Spread the mascarpone cream evenly over the completely cooled brownie slab with an offset spatula. Create a smooth surface or shallow swirls without pressing heavily into the brownies.
Chill Until Set
Refrigerate the topped brownies uncovered for 1 hour, or until the mascarpone layer feels firm enough to slice without flowing over the edges.
Dust with Cocoa Powder
Place the remaining cocoa powder in a fine-mesh sieve and dust it evenly over the chilled mascarpone layer. Apply the cocoa shortly before serving for the driest, most defined finish.
Slice and Serve
Cut the brownies into 16 squares with a sharp knife. Wipe the blade clean between cuts to keep the mascarpone layers neat. Serve chilled or let the brownies stand at room temperature for about 10 minutes for a softer texture.
Tips for Success
- Use a metal baking pan rather than a glass pan for more even baking and cleaner brownie edges.
- Let the melted chocolate mixture cool slightly before adding it to the eggs so the eggs do not begin to cook.
- Do not overbake the brownie base. It will continue to firm as it cools, and a clean toothpick can indicate a dry result.
- Keep the mascarpone and heavy cream cold so the topping whips efficiently and holds its shape.
- Stop whipping as soon as medium peaks form. Overmixed mascarpone cream can become grainy or begin to separate.
- Chill before slicing, and clean the knife after every cut for distinct chocolate and cream layers.
Storage, Freezing, and Make-Ahead Instructions
Store Tiramisu Brownies in a single layer in an airtight container in the refrigerator for up to 4 days. If the container lid might touch the topping, insert several toothpicks near the edges to support a loose covering without disturbing the mascarpone cream.
These brownies should not be stored at room temperature for extended periods because the topping contains mascarpone and heavy cream. Return them to the refrigerator within 2 hours of serving.
For make-ahead preparation, bake and cool the brownie base up to 1 day in advance. Wrap it tightly and keep it at room temperature, then add the mascarpone topping and cocoa powder before chilling.
For freezing, freeze the untopped brownie base for up to 2 months. Wrap it tightly in plastic wrap and place it in a freezer-safe container. Thaw at room temperature before adding the mascarpone cream. Freezing the fully assembled brownies is not recommended because the mascarpone topping may release moisture and become grainy after thawing.
FAQ
Can I make Tiramisu Brownies ahead of time?
Yes. The assembled brownies can be refrigerated for up to 1 day before serving. For the freshest appearance, wait to dust the top with cocoa powder until shortly before slicing.
Why is my mascarpone topping runny?
The mascarpone or cream may have been too warm, or the mixture may not have been whipped long enough. Chill the bowl and topping for 15 minutes, then whip briefly on medium speed. Stop as soon as it holds medium peaks.
Can I make these brownies without espresso powder?
Yes, but they will taste like chocolate brownies with mascarpone topping rather than tiramisu-inspired brownies. Replace the dissolved espresso with 1 teaspoon (5 ml) of water so the batter consistency remains similar.
How do I know when the brownie base is done?
The edges should be set, the center should not look liquid, and a toothpick inserted near the edge should have moist crumbs attached. A toothpick inserted directly in the center may show more chocolate because the brownies are intentionally fudgy.
Can I use an 8-inch square pan?
Yes, but the brownie layer will be thicker and will need additional baking time. Begin checking at 35 minutes and continue until the edges are set and a toothpick near the edge shows moist crumbs.
