Fudgy Tiramisu Brownies (Coffee & Mascarpone)
Equipment
- 9×13-inch baking pan
- Parchment paper
- Electric mixer
- Mixing bowls
- Spatula
- Fine mesh sieve For dusting cocoa
Ingredients
- For the Brownie Base:
- 1 cup unsalted butter melted
- 2 cups granulated sugar
- 4 large eggs
- 1 tsp vanilla extract
- 1 cup all-purpose flour
- ¾ cup unsweetened cocoa powder
- ½ tsp salt
- For the Mascarpone Layer:
- 8 oz mascarpone cheese softened
- ½ cup powdered sugar
- 1 tsp vanilla extract
- 1 cup heavy cream
- For the Coffee Finish:
- 2 tbsp espresso or strong coffee cooled
- 1 tbsp cocoa powder for dusting
Instructions
- Preheat oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper.
- Make brownie batter: In a large bowl, mix melted butter and sugar. Add eggs one at a time, beating well after each. Stir in vanilla. Fold in flour, cocoa, and salt until just combined. Pour into prepared pan.
- Bake: Bake for 25-30 minutes until a toothpick comes out with moist crumbs. Cool completely in the pan.
- Make mascarpone layer: In a large bowl, beat mascarpone, powdered sugar, and vanilla until smooth. In a separate bowl, whip heavy cream to stiff peaks. Gently fold whipped cream into mascarpone until no streaks remain.
- Assemble: Spread the mascarpone mixture evenly over the cooled brownies. Smooth with a spatula.
- Coffee finish: Brush or drizzle cooled espresso over the mascarpone layer. Dust with cocoa powder using a fine-mesh sieve.
- Chill: Refrigerate for at least 2 hours before slicing. For clean cuts, use a hot knife (dip in hot water and wipe clean between each slice).
- Serve: Cut into 16 squares and serve chilled or at room temperature.
What to Expect
- Bottom layer: Fudgy, chocolate brownie with crispy edges
- Middle layer: Creamy, tangy mascarpone – like tiramisu filling
- Top layer: Cocoa dusting with a hint of espresso
Each bite delivers the richness of a brownie, the creaminess of tiramisu, and a subtle coffee kick that ties it all together.
Why This Recipe Works
- Two desserts in one – Brownie meets tiramisu
- Fudgy, not cakey – Perfect brownie texture
- Creamy mascarpone layer – Authentic tiramisu flavor
- Coffee kick – Espresso enhances the chocolate
- Make-ahead friendly – Tastes even better the next day
For perfect mascarpone cream, Serious Eats recommends using high-quality mascarpone and whipping just until stiff peaks form.
Chef Secrets
| Secret | Why It Works |
|---|---|
| Cool brownies completely | Prevents mascarpone from melting |
| Use room temperature mascarpone | No lumps in cream |
| Whip cream to stiff peaks | Light and airy texture |
| Dust with cocoa just before serving | Prevents cocoa from absorbing moisture |
| Chill before slicing | Clean, neat squares |
Variations
| Variation | Ingredients to Add |
|---|---|
| Nutella Swirl | Swirl Nutella into brownie batter before baking |
| Vegan | Use flax eggs + vegan butter + coconut cream |
| Gluten-Free | Use 1:1 gluten-free flour blend |
| Extra Coffee | Add 2 tsp instant coffee to brownie batter |
| Berry Tiramisu | Top with fresh raspberries or strawberries |
Troubleshooting
| Problem | Why It Happens | The Fix |
|---|---|---|
| Brownies are cakey | Too much flour or overmixed | Fold gently; measure flour accurately |
| Mascarpone layer is runny | Not enough chilling or cream not stiff | Chill longer; whip cream more |
| Cocoa powder clumps | Dusting on moist surface | Dust just before serving |
| Brownies crumble when cutting | Not chilled enough | Chill at least 2 hours |
Storage
- Refrigerator: 3-4 days (covered)
- Freezer: 2 months (without mascarpone layer)
- Serve: Chilled or at room temperature
Frequently Asked Questions (FAQ)
Can I use cream cheese instead of mascarpone?
Yes, but mascarpone is richer and more authentic. Cream cheese will be tangier.
How do I keep the mascarpone layer from melting?
Make sure the brownies are completely cool before adding the mascarpone.
Can I make these ahead of time?
Yes! They taste even better the next day as the flavors meld.
Why are my brownies dry?
Over-baked or too much flour. Check at 25 minutes and use the toothpick test.
Can I use instant coffee?
Yes. Dissolve 2 tsp instant coffee in 2 tbsp hot water, then cool before using.
