Tiramisu Brownies combine a fudgy espresso-infused brownie base with a creamy mascarpone topping and a dusting of cocoa powder for a layered dessert inspired by classic tiramisu.
1/2 cup unsalted butter
6 ounces dark chocolate, chopped
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1 tablespoon espresso powder dissolved in 1 tablespoon hot water
1/2 cup all-purpose flour
1/4 cup unsweetened cocoa powder
1/4 teaspoon salt
8 ounces mascarpone cheese, softened
1 cup heavy cream, cold
1/2 cup powdered sugar
1 tablespoon coffee liqueur optional
2 tablespoons unsweetened cocoa powder for dusting
Preheat oven to 350°F and line an 8×8-inch pan with parchment paper.
Melt butter and chocolate together until smooth. Cool slightly.
Whisk in sugar, then add eggs one at a time. Stir in vanilla and espresso.
Fold in flour, cocoa powder, and salt until just combined.
Spread batter in pan and bake 20 to 25 minutes. Cool completely.
Whip heavy cream to soft peaks. Beat mascarpone with powdered sugar and liqueur, then fold in whipped cream.
Spread mascarpone mixture over cooled brownies and refrigerate at least 2 hours.
Dust with cocoa powder before slicing and serving.
Cool brownies fully before adding topping. Chill thoroughly for clean slices.
