How to Make Decadent Chocolate Mousse Brownies

• Preheat your oven to 350°F (175°C) and grease a 9x9-inch baking pan or line it with parchment paper.
• Melt ½ cup of unsalted butter with 8 ounces of bittersweet or semi-sweet chocolate over low heat, stirring until smooth; then remove from heat.
• Whisk together 1 cup of granulated sugar and 2 large eggs until well combined, then stir in the cooled chocolate mixture and 1 teaspoon of vanilla extract until smooth.
• Gently fold in ½ cup of all-purpose flour and ¼ cup of unsweetened cocoa powder, then pour the batter into your prepared pan.
• Bake for 20-25 minutes or until a toothpick comes out with a few moist crumbs; let cool in the pan.
• Melt 8 ounces of chopped bittersweet chocolate in a heatproof bowl over simmering water, stirring until smooth; let cool slightly.
• Whip 1 cup of heavy cream until soft peaks form, then fold in the cooled chocolate until fully incorporated.
• Pour the mousse over the cooled brownie base and refrigerate for at least 2 hours or until set.
• Once chilled, slice the brownies into squares and garnish as desired before serving.
