1. Preheat oven to 325°F (165°C). Line an 8x8-inch pan with parchment paper.
2. In a bowl, whisk melted butter, sugar, eggs, and vanilla until smooth and pale.
3. Sift in cocoa powder, flour, and salt. Mix until just combined. Fold in melted chocolate.
4. Spread the batter evenly into the prepared pan. Bake for 20–24 minutes or until edges are set and center is slightly fudgy.
5. Let the brownie cool completely in the pan.
6. For the mousse, melt chocolate in the microwave or over a double boiler. Let it cool slightly.
7. In a cold mixing bowl, whip cream with vanilla and salt until soft peaks form.
8. Fold whipped cream gently into melted chocolate until fully incorporated.
9. Spread mousse evenly over the cooled brownies. Chill for at least 2 hours or overnight.
10. Slice and serve with whipped cream or berries if desired.
For a twist, add 1 tsp instant espresso to the mousse for a mocha version.
Substitute coconut cream for a dairy-free mousse.
