Directions

Preheat Oven: Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper.
Make the Brownies: In a medium saucepan, melt the butter and semisweet chocolate together over low heat, stirring until smooth. Remove from heat and let cool slightly.
Mix Wet Ingredients: Stir in the sugar, then add eggs one at a time, mixing well after each. Add vanilla extract.
Combine Dry Ingredients: Gently fold in the flour and salt until just combined. Do not overmix.
Bake: Pour brownie batter into the prepared pan and bake for 20–25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Allow to cool completely.
Prepare the Mousse: In a chilled mixing bowl, whip the heavy cream, powdered sugar, and vanilla extract until soft peaks form. Gently fold in the melted chocolate until smooth and airy.
Assemble: Spread the chocolate mousse evenly over the cooled brownies. Chill in the refrigerator for at least 30 minutes to allow the mousse to set.
Serve: Slice into squares and serve chilled. Optionally, garnish with chocolate shavings or berries.
