Tiramisu Brownies Cake

A rich fudgy brownie base topped with a creamy mascarpone tiramisu layer and dusted with cocoa powder for a decadent dessert mash-up.

Ingredients

Scale
  • ½ cup (113 g) unsalted butter, melted
  • 1 cup (200 g) granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ⅓ cup (35 g) unsweetened cocoa powder
  • ½ cup (65 g) all-purpose flour
  • ¼ teaspoon salt
  • 1 cup (240 ml) strong brewed espresso, cooled
  • 2 tablespoons granulated sugar (for espresso)
  • 2 tablespoons coffee liqueur (optional)
  • 8 ounces (225 g) mascarpone cheese, room temperature
  • 1 cup (240 ml) heavy cream
  • ¼ cup (30 g) powdered sugar
  • 1 teaspoon vanilla extract (for filling)
  • 2 tablespoons unsweetened cocoa powder, for dusting

Instructions

  1. Preheat oven to 350 °F (175 °C). Line an 8×8″ baking pan with parchment, leaving an overhang.
  2. In a bowl, whisk together cocoa powder, flour, and salt; set aside.
  3. In a separate bowl, stir melted butter and granulated sugar until combined. Whisk in eggs one at a time, then vanilla.
  4. Fold flour mixture into wet ingredients until just combined. Spread batter evenly in prepared pan.
  5. Bake 20–25 minutes, or until a toothpick inserted near center comes out with moist crumbs. Cool completely.
  6. Meanwhile, stir espresso, 2 Tbsp sugar, and coffee liqueur until sugar dissolves; let cool.
  7. In a chilled bowl, whip heavy cream to soft peaks. In another bowl, beat mascarpone, powdered sugar, and vanilla until smooth.
  8. Gently fold whipped cream into mascarpone mixture until no streaks remain.
  9. Brush cooled brownie top evenly with espresso mixture. Spread mascarpone filling over brownies in an even layer.
  10. Cover and refrigerate at least 3 hours (or overnight) to set.
  11. Before serving, dust top generously with unsweetened cocoa powder and cut into 12 squares.

Notes

  • Use gel or Dutch-process cocoa for a deeper chocolate flavor in the brownies.
  • Chill the mascarpone bowl and beaters beforehand to help the cream whip up faster.
  • For extra coffee kick, soak a few ladyfinger halves in espresso and layer between brownies and filling.
  • Best enjoyed within 2 days; keep refrigerated.
