Ingredients
  

Brownie Base:

  • 1/2 cup unsalted butter
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 tsp salt
  • 1/4 tsp baking powder

Chocolate Mousse Topping:

  • 1 cup heavy whipping cream
  • 4 oz semi-sweet or bittersweet chocolate, melted and slightly cooled
  • 2 tbsp powdered sugar
  • 1 tsp vanilla extract

Instructions
 

Brownie Base:

  • Preheat oven to 350°F (175°C). Grease and line an 8x8 inch baking pan.
  • Melt butter and stir in sugar until combined.
  • Beat in eggs and vanilla extract until smooth.
  • Sift cocoa powder, flour, salt, and baking powder; gradually fold into wet ingredients.
  • Pour batter into prepared pan and bake for 20-25 minutes, or until a toothpick inserted near the center comes out with moist crumbs. Cool completely.

Chocolate Mousse Topping:

  • Whip heavy cream with powdered sugar and vanilla until soft peaks form.
  • Gently fold melted chocolate into whipped cream until fully combined and smooth.
  • Spread mousse evenly over cooled brownie base.
  • Refrigerate at least 2 hours until mousse is set before slicing and serving.

Notes

  • Use high-quality chocolate for best flavor and smooth texture.
  • Ensure brownies are fully cooled before adding mousse to prevent melting.
  • For a gluten-free option, substitute flour with almond flour or gluten-free baking mix.
  • Garnish with fresh berries or a dusting of cocoa powder for presentation.
  • Store covered in the refrigerator for up to 3 days.
