• ⅓ cup unsweetened cocoa powder
• ½ cup all-purpose flour
• ¼ tsp salt
• ¼ tsp baking powder

For the Chocolate Mousse Layer:

• 1 cup semi-sweet chocolate chips
• 1½ cups heavy whipping cream (divided)
• 2 tbsp powdered sugar
• 1 tsp vanilla extract

Optional Add-ins:

• ½ cup chopped nuts in the brownie layer
• A sprinkle of sea salt on top
• Shaved chocolate or cocoa powder for garnish

Tools You’ll Need

• 8×8-inch baking pan
• Parchment paper
• Mixing bowls
• Hand mixer or stand mixer
• Spatula
• Saucepan or microwave-safe bowl

Step-by-Step Instructions

Step 1: Preheat the Oven and Prepare the Pan
Preheat your oven to 350°F (175°C).
Line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy removal.

Step 2: Make the Brownie Layer
In a medium saucepan, melt the butter over low heat.
Remove from heat and stir in sugar, eggs, and vanilla extract.
Add cocoa powder, flour, salt, and baking powder, and mix until just combined.
Pour the batter into the prepared pan and spread evenly.

Step 3: Bake the Brownies
Bake for 20–25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Let the brownies cool completely in the pan.

Step 4: Make the Chocolate Mousse
In a microwave-safe bowl or over a double boiler, melt the chocolate chips with ½ cup of heavy cream until smooth.
Let cool slightly.
In a separate bowl, whip the remaining 1 cup heavy cream with powdered sugar and vanilla extract until soft peaks form.
Gently fold the cooled chocolate mixture into the whipped cream until fully combined and fluffy.

Step 5: Assemble the Brownies
Spread the chocolate mousse evenly over the cooled brownie layer.
Chill in the refrigerator for at least 2 hours, or until the mousse is set.

Step 6: Slice & Serve
Lift the brownies out of the pan using the parchment overhang.
Cut into squares and garnish with shaved chocolate or a dusting of cocoa powder if desired.

Tips for Success
Cool Brownies Completely – Prevents the mousse from melting.
Fold Gently – Keep the whipped cream airy for a light mousse.
Chill Thoroughly – Makes slicing easier and keeps the layers neat.
Use Good Quality Chocolate – It makes a big difference in flavor.
Wipe Knife Between Cuts – For clean, sharp brownie slices.

Serving Suggestions
With Fresh Berries – Strawberries or raspberries balance the richness.
With Whipped Cream – Adds extra lightness to the plate.
With Coffee or Espresso – The perfect pairing for rich chocolate desserts.
At Parties – Serve chilled on a dessert platter for maximum impact.
