How to Make It
Follow these steps for delicious results.
Preheat the oven
Preheat the oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper to prevent sticking.
Melt the butter
Melt the butter in a saucepan over medium heat. Remove from heat and stir in sugar, eggs, and vanilla until well combined.
Mix the dry ingredients
Beat in cocoa powder, flour, and salt until fully incorporated. Pour the brownie batter into the prepared pan.
Bake the brownies
Bake for 20-25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Let the brownies cool completely in the pan.
Melt the chocolate
Melt the semisweet chocolate in a heatproof bowl over simmering water, stirring until smooth. Allow to cool slightly.
Whip the cream
Whip the heavy cream in a medium bowl until soft peaks form. Gently fold in the melted chocolate until fully combined.
Sweeten the mousse
Fold in the powdered sugar until the mixture is sweetened to your preference.
Spread the mousse
Spread the chocolate mousse evenly over the cooled brownies. Refrigerate for about 2 hours, or until the mousse is set.
Slice and serve
Slice the brownies into squares and serve. For an extra touch, consider drizzling with chocolate ganache if desired.
How to Store It
Fridge: up to 3 days in an airtight container.
