Preparation

  • Preheat your oven and prepare your baking pan by greasing it lightly or lining it with parchment paper.
  • In a mixing bowl, whisk together the melted butter and granulated sugar until well combined.
  • Add the eggs one at a time to the butter-sugar mixture, mixing thoroughly after each addition.
  • Stir in the vanilla extract.
  • Gradually sift in the cocoa powder, flour, salt, and baking powder, gently folding until well incorporated.
  • Pour the brownie batter into the prepared baking pan, spreading it evenly.
  • Bake the brownies until set, with firm edges and a slightly soft center.

Mousse Preparation

  • While the brownies cool, melt chocolate and milk together in a double boiler or microwave until smooth.
  • Allow the melted chocolate to cool slightly, then whisk in powdered sugar until smooth.
  • Whip the chilled heavy cream until soft peaks form and fold it gently into the chocolate mixture.
  • Pour the mousse over the cooled brownies and spread evenly.
  • Refrigerate to set the mousse, allowing flavors to meld.

Serving
