  • Total Time: 2 hours 55 minutes
  • Yield: 12 servings

Ingredients

Dry Ingredients

  • 1 ½ cups (187.5 g) all-purpose flour
  • 1 tablespoon cornstarch
  • ⅓ cup (39 g) Dutch-processed cocoa powder
  • ½ teaspoon baking powder
  • ¼ teaspoon kosher salt

Wet Ingredients and Others

  • 4 large eggs, (room temperature)
  • 2 cups (400 g) granulated sugar
  • ¾ cup (1 ½ sticks / 170 g) unsalted butter
  • 2 teaspoons vanilla bean paste
  • 1 ½ cups (357 g) heavy whipping cream, (cold, divided)
  • 1 cup chocolate chips, (semi-sweet or your preference)
  • Chocolate curls, (for garnish, optional)

Instructions

  1. Preheat Oven and Prepare Baking Dish: Preheat the oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, leaving an overhang on the sides to easily lift the brownies out later.
  2. Whisk Dry Ingredients: In a large bowl, whisk together the all-purpose flour, cornstarch, Dutch-processed cocoa powder, baking powder, and kosher salt until evenly combined. Set aside.
  3. Beat Wet Ingredients: In the bowl of a stand mixer fitted with the paddle attachment, combine the eggs, granulated sugar, unsalted butter, and vanilla bean paste. Beat on medium speed until the mixture becomes light, fluffy, and well incorporated.
  4. Combine Wet and Dry Ingredients: With the mixer off, add the dry ingredient mixture to the wet ingredients. Turn the mixer to low speed and mix until just combined, ensuring a smooth brownie batter without overmixing.
  5. Bake Brownie Layer: Pour the batter into the prepared baking dish, spreading it evenly. Bake in the preheated oven for 30-35 minutes. Check doneness by ensuring the edges are set and the center still appears shiny and slightly moist, which indicates a fudgy texture.
  6. Cool Brownies: Remove the brownies from the oven and let them cool completely at room temperature in the baking dish.
  7. Heat Heavy Cream: In a microwave-safe bowl, heat ½ cup of the cold heavy cream for about 50 seconds, or until warm but not boiling, adjusting time based on your microwave’s strength.
  8. Melt Chocolate Chips: Add the semi-sweet chocolate chips to the warm cream and stir continuously until the chocolate is fully melted and the mixture is smooth. Allow this chocolate-cream mixture to cool to room temperature.
  9. Beat Remaining Cream: Pour the remaining 1 cup of heavy whipping cream into a medium bowl. Using a hand-held or stand mixer, whip the cream until stiff peaks form, meaning the cream holds firm peaks when the whisk is lifted.
  10. Fold Chocolate Mixture into Whipped Cream: Gently fold the cooled chocolate-cream mixture into the whipped cream using a spatula, combining carefully to maintain the mousse’s light and airy texture.
  11. Assemble Mousse Layer: Spread the chocolate mousse evenly over the cooled brownie base in the baking dish.
  12. Garnish: Optionally, sprinkle chocolate curls over the mousse for a decorative and decadent finish.
  13. Chill: Refrigerate the assembled brownies for at least 2 hours and up to overnight to allow the mousse to set firmly before slicing and serving.

Notes

  • Room temperature eggs help achieve a smoother, more consistent batter.
  • Do not overbake the brownies; the center should remain shiny and slightly moist for a fudgy texture.
  • Use high-quality semi-sweet chocolate chips or your preferred chocolate for the mousse for the best flavor.
  • Heavy cream must be cold before whipping to reach stiff peaks successfully.
  • The mousse needs adequate chilling time to firm up properly, so plan ahead.
  • Chocolate curls are optional but add a beautiful presentation touch.
