Decadent chocolate brownies layered with light mousse for a luscious finish.

# Ingredients List:

→ Brownie Base

01 - 1 cup unsalted butter (2 sticks)
02 - 2 cups granulated sugar
03 - 4 large eggs
04 - 1 teaspoon vanilla extract
05 - 1 cup all-purpose flour
06 - 1 cup unsweetened cocoa powder
07 - ½ teaspoon salt
08 - ½ teaspoon baking powder

→ Chocolate Mousse

09 - 1½ cups heavy whipping cream
10 - 8 oz semi-sweet chocolate, chopped
11 - 3 large egg whites
12 - ¼ cup granulated sugar
13 - 1 teaspoon vanilla extract

# How to Make It:

01 - Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking dish.
02 - In a medium saucepan over medium heat, melt the butter. Stir in the sugar until thoroughly combined.
03 - Remove from heat and allow to cool slightly. Whisk in the eggs and vanilla extract until fully blended.
04 - Sift together all-purpose flour, cocoa powder, salt, and baking powder in a separate bowl.
05 - Gradually fold the dry ingredients into the wet mixture, stirring just until combined; avoid overmixing.
06 - Pour batter evenly into the prepared pan. Bake for 30-35 minutes or until a toothpick inserted near the center comes out with moist crumbs.
07 - Remove from oven and cool completely in the pan before proceeding.
08 - Using a double boiler or microwave, melt the semi-sweet chocolate until smooth. Allow to cool slightly.
09 - Whip heavy cream in a large bowl until soft peaks form.
10 - In a separate bowl, beat egg whites until foamy. Gradually add sugar and continue beating until stiff peaks form.
11 - Gently fold melted chocolate into whipped cream until uniform. Then carefully fold in the egg whites, preserving airiness.
12 - Spread the mousse evenly over cooled brownies. Cover and refrigerate for 1-2 hours to set before serving.

# Extra Information:

01 - Ensure brownies are fully cooled to prevent mousse from melting when layered.
