Ingredients

Scale
  • ⅓ cup (35g) unsweetened cocoa powder
  • ½ cup (65g) all-purpose flour
  • ¾ cup (150g) granulated sugar
  • 6 tablespoons (85g) unsalted butter, melted and slightly cooled
  • 1 large egg, room temperature
  • 1 teaspoon pure vanilla extract
  • A pinch of salt
  • 6 ounces (170g) dark chocolate (70% cocoa), chopped
  • 1 cup (240ml) heavy cream, chilled
  • 2 tablespoons (15g) powdered sugar
  • ½ teaspoon vanilla extract
  • 1 cup (150g) fresh strawberries, hulled and sliced
  • 1 tablespoon (12g) granulated sugar
  • 1 teaspoon fresh lemon juice
  • Optional: a splash of balsamic vinegar

Instructions

  1. Preheat your oven to 350°F (175°C). Grease the baking pan lightly with butter or line it with parchment paper for easy removal.
  2. Make the brownie base: In a medium bowl, sift together cocoa powder, flour, and salt. In a separate bowl, whisk melted butter with sugar until combined. Add the egg and vanilla extract, whisking until smooth.
  3. Gradually add the dry ingredients to the wet, folding gently with a spatula until just combined. Be careful not to overmix; you want a thick batter.
  4. Pour the batter into the prepared pan and spread evenly. Bake for 15-18 minutes or until a toothpick inserted comes out with a few moist crumbs—not dry.
  5. Remove brownies from the oven and let cool completely in the pan, about 30 minutes.
  6. Prepare the chocolate mousse: Melt the chopped dark chocolate in a heatproof bowl over simmering water (double boiler method), stirring until smooth. Let it cool slightly.
  7. In a chilled mixing bowl, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form.
  8. Fold about a third of the whipped cream into the cooled chocolate gently to lighten it. Then fold in the remaining cream until fully combined and smooth. Avoid deflating the mousse.
  9. Assemble the dessert: Spread the mousse evenly over the cooled brownie base in the pan. Smooth the top with a spatula.
  10. Prepare the strawberry topping: In a small bowl, toss sliced strawberries with sugar and lemon juice (and balsamic vinegar if using). Let sit for 10 minutes to macerate and release their juices.
  11. Scatter the strawberries and their juices over the mousse layer, gently pressing some into the mousse for extra flavor infusion.
  12. Refrigerate the entire dessert for at least 2 hours (or overnight) to set properly.
  13. When ready to serve, cut into squares and use a hot knife dipped in warm water for clean slices. Serve chilled.

Notes

Use a double boiler to melt chocolate to prevent scorching. Chill bowl and beaters before whipping cream for best results. Fold mousse gently to keep it airy. Let brownie cool completely before adding mousse to avoid mixing layers. Macerate strawberries for at least 10 minutes to enhance flavor. For gluten-free, substitute almond flour; for dairy-free, use coconut cream and dairy-free chocolate.
