Ingredients
  

For the Brownies
  • 3/4 cup butter melted
  • 1 1/2 cups sugar
  • 1 tsp vanilla extract
  • 2 eggs
  • 1/2 cup cocoa powder
  • 1/2 tsp salt
  • 3/4 cup all-purpose flour
For the Mousse
  • 3/4 cup miniature marshmallows
  • 4 oz semi-sweet chocolate chopped
  • 1/4 cup milk
  • 1 cup heavy whipping cream
  • 1 Chocolate ganache for drizzling, optional

Equipment

  • 9x9 inch square baking pan
  • Large bowl
  • Saucepan
  • Stand mixer

Method
 

  1. Preheat your oven to 350 degrees F. Line a 9x9" square baking pan with foil, letting the foil extend over the edges. Spray the foil with cooking spray and set aside.
  2. In a large bowl, mix the melted butter and sugar until smooth. Add the eggs one at a time, mixing well after each. Stir in the vanilla extract. Finally, add the cocoa powder, salt, and flour, mixing until a soft batter forms.
  3. Pour the batter into the prepared pan and spread it evenly. Bake for 22-25 minutes, or until a toothpick inserted near the center comes out clean or with moist crumbs. Let the brownies cool completely.
  4. To make the mousse: In a saucepan over low heat, combine the miniature marshmallows, chopped chocolate, and milk. Stir often until melted and smooth. Let this mixture cool completely, about 15-20 minutes.
  5. After the chocolate mixture has cooled, whip the heavy cream in a stand mixer until stiff peaks form. Gently fold the cooled chocolate mixture into the whipped cream until combined. Spread this mousse evenly over the cooled brownies.
  6. Refrigerate the brownies for at least 1 hour to allow the mousse to set. Before serving, drizzle with chocolate ganache if you like. Store any leftovers in the refrigerator.

Notes

To make chocolate ganache: Combine 1/2 cup chocolate chips and 1/4 cup heavy whipping cream in a microwave-safe bowl. Heat on high for about 15-20 seconds, stir, and continue heating in 10-second increments until smooth.
