Ingredients

Scale
  • 1 cup (226g) unsalted butter
  • 2 cups (400g) granulated sugar
  • 4 large eggs, at room temperature
  • 1 tablespoon pure vanilla extract
  • 1 cup (85g) unsweetened cocoa powder
  • 1 cup (125g) all-purpose flour
  • 1/2 teaspoon salt
  • 1 cup (175g) semi-sweet chocolate chips
  • 2 cups (350g) high-quality dark chocolate, chopped
  • 3 tablespoons unsalted butter
  • 4 large eggs, separated
  • 1/4 cup (50g) granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1 cup (240ml) heavy whipping cream
  • Pinch of salt
  • Chocolate curls, cocoa powder, or fresh berries for garnish (optional)

Instructions

  1. Prepare Your Baking Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang on the sides for easy removal. Lightly grease the parchment paper.
  2. Make the Brownie Base:
    1. In a large microwave-safe bowl, melt the butter. Add the sugar and whisk until well combined.
    2. Add the eggs one at a time, whisking well after each addition.
    3. Stir in the vanilla extract.
    4. In a separate bowl, sift together the cocoa powder, flour, and salt.
    5. Gradually fold the dry ingredients into the wet ingredients until just combined.
    6. Fold in the chocolate chips.
    7. Pour the brownie batter into the prepared pan and smooth the top with a spatula.
  3. Bake the Brownies:
    1. Bake for 25-30 minutes or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
    2. Allow the brownies to cool completely in the pan on a wire rack before adding the mousse layer.
  4. Prepare the Chocolate Mousse:
    1. In a heatproof bowl set over a pan of simmering water (double boiler), melt the chopped dark chocolate and butter together. Stir occasionally until smooth and completely melted. Remove from heat and let cool slightly.
    2. In a clean bowl, beat the egg whites with a pinch of salt until foamy. Gradually add the sugar and continue beating until soft peaks form.
    3. In another bowl, beat the heavy cream and vanilla extract until medium peaks form.
    4. Whisk the egg yolks into the cooled chocolate mixture one at a time.
    5. Gently fold the whipped cream into the chocolate mixture until almost incorporated.
    6. Carefully fold in the egg white mixture in three additions, being careful not to deflate the mousse.
  5. Assemble and Chill:
    1. Once the brownie base is completely cool, spread the chocolate mousse evenly over the top.
    2. Refrigerate for at least 2 hours, or preferably overnight, to allow the mousse to set.
  6. Serve:
    1. When ready to serve, lift the brownies out of the pan using the parchment paper overhang.
    2. Cut into squares with a sharp knife, wiping the blade clean between cuts for clean edges.
    3. Garnish with chocolate curls, a light dusting of cocoa powder, or fresh berries if desired.

Notes

Pro Tips:

  • For the fudgiest brownies, don’t overbake! The residual heat will continue cooking them after removal from the oven.
  • Use room temperature eggs for both the brownie base and mousse for better incorporation.
  • High-quality chocolate makes a significant difference in the flavor. Use the best you can afford.
  • For cleaner cuts, refrigerate the brownies first, then dip your knife in hot water and wipe clean between slices.
  • If you’re concerned about raw eggs in the mousse, you can use pasteurized eggs or a cooked egg method.
  • For a flavor twist, add a tablespoon of coffee liqueur or orange zest to the mousse layer.
