Chocolate Mousse Brownies

Preheat oven to 350ºF. Line a 9×13-inch baking pan with foil and grease lightly with cooking spray; set aside.

In a large mixing bowl, whisk together the sugar, brown sugar, melted butter, milk, eggs, and vanilla.

In a separate mixing bowl, combine flour, cocoa, baking powder, and salt.

Fold the dry ingredients into the wet until combined. Pour the batter into prepared pan.

Bake for 18-20 minutes, or until a toothpick inserted into the center comes out with few moist crumbs. Place the pan onto a cooling rack and let cool completely.

In the meantime, prepare the chocolate mousse frosting. Place all ingredients in a mixing bowl and whip until mixture holds a stiff peak.

Remove the cooled brownies from the pan by holding onto the sides of the foil. Spread the chocolate mousse frosting over the entire cake. Cut into squares, garnish with grated chocolate, and serve.
