These tiramisu brownies are a rich dessert mashup of fudgy chocolate base, creamy mascarpone layer, and a bold espresso soak — finished with a dusting of cocoa for the perfect finish.
For the brownie layer:
½ cup (1 stick) unsalted butter
4 oz dark chocolate, chopped
¾ cup granulated sugar
¼ cup brown sugar
2 large eggs
1 tsp vanilla extract
½ cup all-purpose flour
2 tbsp cocoa powder
½ tsp salt
1 tsp instant espresso (optional)
For the mascarpone layer:
8 oz mascarpone cheese
1 egg yolk (or whole egg)
3 tbsp sugar
½ tsp vanilla extract
2–3 tbsp heavy cream
For the espresso soak:
¼ cup cooled espresso or strong coffee
1 tbsp coffee liqueur (optional)
1 tsp sugar (optional)
For topping:
1 tbsp unsweetened cocoa powder (for dusting)
Preheat oven to 350°F. Line an 8×8-inch pan with parchment.
Melt butter and chocolate together; let cool slightly. Stir in sugars, eggs, and vanilla.
Fold in flour, cocoa powder, salt, and optional espresso powder. Pour into pan.
Mix mascarpone, egg yolk, sugar, vanilla, and cream until smooth. Spread over brownie layer.
Bake for 35–40 minutes, until just set. Cool completely, then chill at least 2 hours.
Brush top with coffee soak. Let rest 15 minutes.
Dust with cocoa powder. Slice and serve chilled or at room temperature.
