Decadent Tiramisu Brownies Recipe

For the Mascarpone Cream

• 8 oz (225 g) mascarpone cheese, chilled
• 1 cup (240 ml) cold heavy cream
• ½ cup (60 g) powdered sugar, sifted
• 1½ tsp pure vanilla extract
• 1 tsp espresso powder (for depth)

Garnish (Optional)

• Unsweetened cocoa powder for dusting
• Dark-chocolate shavings or curls

Instructions

1. Step 1: Prep like a pro. Preheat oven to 350 °F (175 °C). Line an 8-inch square metal pan with parchment, leaving overhang for easy lifting. Lightly butter exposed sides.
2. Step 2: Make the brownie batter. In a medium saucepan over low heat, melt butter and bittersweet chocolate, stirring until silky smooth. Remove from heat; whisk in both sugars until dissolved. Let cool 3 minutes so the eggs won’t scramble. Whisk in eggs one at a time, then vanilla. Sift cocoa, flour, salt, and baking powder over the mixture; fold with a spatula just until no dry streaks remain.
3. Step 3: Bake to fudgy perfection. Pour batter into the prepared pan; smooth the top. Bake 25–28 minutes, until the surface is matte and a toothpick inserted 1 inch from the edge comes out with a few moist crumbs. The center should jiggle slightly—carryover heat finishes it. Cool in the pan on a rack for 15 minutes.
4. Step 4: Create the espresso soak. While the brownies cool, combine warm espresso and sugar in a small saucepan. Simmer 2 minutes until syrupy. Remove from heat; stir in coffee liqueur. Using a skewer, poke holes all over the brownie surface about 1 inch apart. Slowly spoon the syrup over the top, allowing it to seep in. Let stand 30 minutes to absorb fully.
5. Step 5: Whip the mascarpone cloud. In a chilled bowl, beat mascarpone 20 seconds to loosen. Add heavy cream, powdered sugar, vanilla, and espresso powder. Beat on medium-high until soft, pillowy peaks form—stop before it becomes stiff butter. Spread evenly over the cooled, soaked brownies.
6. Step 6: Chill and finish. Cover and refrigerate at least 2 hours (overnight is ideal). Before serving, dust lightly with cocoa and scatter chocolate shavings for that classic tiramisu look. Lift out using parchment handles, slice with a hot dry knife for pristine edges, and prepare for swoons.

Handy Tips

• Espresso shortcut: 1 tsp instant espresso powder dissolved in ½ cup hot water equals the required strong coffee.
• Egg temp hack: Place cold eggs in a bowl of warm tap water for 5 minutes to bring to room temperature quickly.
• Flour swap: For a gluten-free version, substitute a 1:1 gluten-free baking blend containing xanthan gum.
• Don’t overbake: The center should still wobble—remember, it firms as it chills under the mascarpone layer.

Heat Control

Keep the butter–chocolate melt below a gentle simmer; scorched chocolate tastes bitter. When beating the mascarpone cream, medium speed is the sweet spot—too high incorporates excess air and risks separation. The brownies finish baking when the internal temperature hits 195 °F (90 °C) on an instant-read thermometer.

Crunch Factor

The top of these brownies bakes to a delicate, paper-thin crust that crackles under your fork, giving way to a truffle-dense interior. To amplify this contrast, chill the pan uncovered for 15 minutes after baking—rapid cooling sets the crust while preserving the fudgy center
