Ingredients

Scale

Brownie Base

1 cup unsalted butter, melted

2 cups granulated sugar

4 large eggs, room temperature

2 teaspoons vanilla extract

¾ cup Dutch-process cocoa powder

1 cup all-purpose flour

½ teaspoon salt

Chocolate Mousse

2 cups heavy whipping cream, chilled

8 ounces semi-sweet chocolate, melted and slightly cooled

Garnish (Optional)

Chocolate curls or shavings

Fresh berries (raspberries, strawberries)

Whipped cream

 


Instructions

  • Prepare Pan & Oven: Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment.

  • Make Brownie Batter: In a bowl, whisk melted butter and sugar until glossy. Beat in eggs, one at a time, then add vanilla. In a separate bowl, whisk cocoa, flour, and salt. Fold dry ingredients into wet until just combined.

  • Bake Brownies: Spread batter evenly in pan. Bake 30–35 minutes, or until a toothpick inserted comes out with moist crumbs. Let cool completely in pan.

  • Make the Mousse: Melt chocolate (double boiler or microwave). Allow to cool slightly. Whip heavy cream until soft peaks form. Gently fold in melted chocolate until light and fluffy.

  • Assemble: Spread mousse evenly over cooled brownies. Chill at least 2 hours (overnight is best) to set.

 

  • Serve: Garnish with chocolate curls, berries, or whipped cream. Slice with a hot knife for clean edges.

Notes

For a stronger chocolate flavor, use bittersweet chocolate in the mousse.

Add a tablespoon of espresso powder to the brownie batter for a mocha twist.

Store brownies in the fridge for up to 5 days, or freeze (well wrapped) for up to 2 months.
