These Chocolate Mousse Brownies feature a dense, fudgy brownie base topped with a light, airy chocolate mousse — the ultimate layered dessert for chocolate lovers.
For the Brownies:
1/2 cup unsalted butter
6 oz semisweet chocolate, chopped
3/4 cup granulated sugar
1/4 cup brown sugar
2 large eggs
1 tsp vanilla extract
3/4 cup all-purpose flour
1/4 cup cocoa powder
1/4 tsp salt
For the Mousse:
6 oz dark or semisweet chocolate, chopped
2 egg yolks
2 tbsp sugar
1 cup heavy cream (divided)
1 tsp gelatin (optional)
1 tsp vanilla extract
Preheat oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper.
Melt butter and chocolate, cool slightly. Whisk in sugars, eggs, and vanilla.
Fold in flour, cocoa, and salt. Bake 25–28 minutes. Cool completely.
For mousse: Melt chocolate; set aside. Whisk yolks, sugar, and 1/3 cup cream in a saucepan until slightly thickened.
Combine with melted chocolate. If using gelatin, dissolve and stir in.
Whip remaining cream to soft peaks; fold into cooled chocolate mixture.
Spread mousse over cooled brownies. Chill 4 hours or overnight.
