  • Total Time: 3 hours (including chilling time)
  • Yield: 9-12 brownies 1x

Ingredients

Scale

Brownie Base

  • 6 oz bittersweet chocolate (60-70% cocoa)
  • 1/2 cup (115g) unsalted butter
  • 3/4 cup (150g) granulated sugar
  • 3 large eggs
  • 1/2 cup (65g) all-purpose flour (or gluten-free flour blend)
  • 2 tbsp cocoa powder
  • 1/4 tsp salt

Chocolate Mousse

  • 4 oz bittersweet chocolate (60-70% cocoa)
  • 1 cup (240ml) heavy cream, chilled
  • 1 tsp vanilla extract

Instructions

  1. Prepare the Brownie Base: Melt the bittersweet chocolate and unsalted butter together until smooth and glossy. In a separate bowl, whisk the eggs and granulated sugar until fluffy. Gently fold the melted chocolate mixture into the eggs and sugar. Sift together the all-purpose flour, cocoa powder, and salt, then fold into the wet ingredients without overmixing. Pour the batter into a parchment-lined baking pan and bake at 350°F (175°C) for 25-30 minutes or until a toothpick comes out mostly clean with a few moist crumbs. Allow to cool completely.
  2. Make the Silky Chocolate Mousse: Chill your mixing bowl and beaters. Whip the heavy cream to soft peaks. Gently melt the chocolate over a bain-marie or in short bursts in the microwave; let it cool slightly. Fold the melted chocolate into a small portion of whipped cream first to lighten it, then carefully fold in the remaining whipped cream, keeping the mousse airy and smooth. Add vanilla extract and mix gently.
  3. Assemble the Layers: Spread the cooled brownie base evenly in the baking pan. Spoon or pipe the chocolate mousse over the brownie layer, smoothing it out evenly. Chill the assembled dessert in the refrigerator for at least 2 hours or overnight to allow the mousse to firm up and flavors to meld.
  4. Serve and Enjoy: Before slicing, dip a sharp knife in hot water, dry it, and cut the brownies into squares or rectangles with clean edges. Optionally, garnish with shaved chocolate, cocoa powder, or fresh berries for an elegant touch. Serve chilled.

Notes

  • Use high-quality chocolate for the best flavor.
  • Bring eggs and butter to room temperature before mixing.
  • Fold ingredients gently to maintain light mousse and tender brownies.
  • Chill thoroughly to set the mousse properly.
  • Line the pan with parchment paper with overhang for easy removal.
  • Store in an airtight container in the refrigerator for up to 4 days.
  • Freeze wrapped tightly for longer storage; thaw overnight before serving.
  • Best served chilled; if preferred softer, leave at room temperature for 15-20 minutes before eating.
