how to make Chocolate Mousse Brownies

Ingredients :

  • 1 cup unsalted butter
  • 8 oz semisweet chocolate, chopped
  • 1 1/4 cup granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1 cup heavy cream
  • 2 oz semisweet chocolate, for mousse
  • 2 oz semisweet chocolate, for ganache

Directions :

  1. Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking pan.
  2. Melt the butter and chocolate together in a large saucepan over low heat, stirring until smooth. Remove from heat and stir in sugar.
  3. Whisk in eggs one at a time, then stir in vanilla.
  4. Add flour and salt, stirring until just combined.
  5. Pour the brownie batter into the prepared pan and spread evenly.
  6. Bake for 20-25 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.
  7. Allow brownies to cool completely.
  8. For the mousse, melt 2 oz of chocolate in a bowl over simmering water. Whip cream to stiff peaks and fold in the melted chocolate. Pour mousse over the cooled brownies and chill for at least 2 hours.
  9. For the ganache, melt the remaining chocolate and pour over the mousse layer. Chill until set.
  10. Cut into squares and serve as desired.

Note: The mousse needs time to set. Chilling makes it easier to slice clean squares. If you want a slightly firmer mousse, chill longer.

how to serve Chocolate Mousse Brownies

Serve these brownies cold or slightly chilled so the mousse and ganache stay firm. Cut with a sharp knife and wipe the knife between cuts for neat edges.

how to store Chocolate Mousse Brownies

Store the brownies in an airtight container in the fridge. They keep well for up to 4 days. If you want to freeze, cut into squares and freeze in a single layer on a tray. Once frozen, stack in a freezer bag with parchment between layers for up to 1 month. Thaw in the fridge before serving.

FAQs

Q: Can I make the brownies a day ahead?
