  • 1 cup (200 g) granulated sugar
  • 2 large eggs, room temperature
  • 1 tsp vanilla extract
  • ½ cup (50 g) unsweetened cocoa powder
  • ½ tsp salt

How to Make Chocolate Mousse Brownies

  1. Preheat your oven to 325°F (165°C). Line a 9×9-inch pan with parchment paper for easy removal.
  2. In a mixing bowl, whisk the melted butter and granulated sugar together until glossy and smooth.
  3. Add the eggs and vanilla extract, whisking vigorously for 30–45 seconds until well combined.
  4. Stir in the cocoa powder and salt until the mixture is smooth and inviting.
  5. Gently fold in the all-purpose flour, mixing just until combined to keep your brownies fudgy.
  6. Spread the batter evenly in your prepared pan, making sure it’s nice and even.
  7. Bake for 25–30 minutes. The edges should be set while the center remains soft — that’s where the magic happens! Cool completely in the pan to allow flavors to deepen.

Delicious Variations to Try

  • Nutty Delight: Fold in ½ cup of chopped walnuts or pecans into the brownie batter for an added crunch and rich flavor.
  • Minty Freshness: Add a few drops of peppermint extract to the chocolate mousse layer to create a refreshing mint chocolate experience.
  • Berry Bliss: Top your mousse brownies with a handful of fresh raspberries or strawberries for a burst of color and taste.
  • Zesty Twist: Incorporate a teaspoon of orange zest into your brownie batter for a lovely, citrusy zing that balances beautifully with the chocolate.
