Chocolate Mousse Brownies are creamy, indulgent and loaded with chocolate, making them the perfect dessert.
Place parchment paper in a 13x9 inches pan so it covers the bottom and 2 sides (to facilitate the brownie removal). Butter the pan and set aside.
Pour the batter into the pan and bake for 30-35 minutes. Check for doneness by inserting a toothpick into the center of the pan, it should come out with just a few crumbles attached. I find that 25-30 minutes in my oven for this recipe is perfect timing.
