How to Make Chocolate Mousse Brownies
Preheat: Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper for easy removal later.
Whisk: In a large bowl, whisk together the melted butter, sugar, eggs, and vanilla extract until well combined and smooth.
Mix Dry Ingredients: Sift in the cocoa powder, flour, salt, and baking powder. Gently fold the mixture together until just combined, being careful not to overmix.
Bake: Pour the brownie batter into the prepared pan. Smooth the top with a spatula. Bake for 20-25 minutes or until a toothpick inserted shows moist crumbs.
Cool: Allow the brownies to cool completely in the pan to ensure the mousse sets properly.
Prepare Mousse: While the brownies cool, combine heated milk with semisweet chocolate in a bowl. Stir until smooth, then let it cool to room temperature.
Whip Cream: In another bowl, whip the heavy cream with powdered sugar until soft peaks form. Carefully fold the cooled chocolate mixture into the whipped cream to create your mousse.
Layer Mousse: Spread the mousse over the cooled brownies evenly. Refrigerate for at least 2 hours to allow the mousse to set.
Make Ganache: For the ganache, heat the cream until just simmering, then pour it over chopped chocolate. Let it sit for a moment before stirring until smooth.
Add Ganache: Pour the ganache over the set mousse, spreading it evenly. Chill the entire dessert for an additional hour before serving.
Optional: Garnish with chocolate shavings or fresh berries for a stunning presentation.
