How to Make Chocolate Mousse Brownies Recipe
Step 1: Prepare the Brownie Base
Preheat your oven to 350°F (175°C). Grease a baking pan with butter or line it with parchment paper. In a mixing bowl, combine the melted butter and sugar. Stir until well combined.
Step 2: Mix in Eggs and Flavors
Add the eggs one at a time, mixing well after each addition. Then stir in the vanilla extract until fully incorporated.
Step 3: Combine Dry Ingredients
In another bowl, whisk together cocoa powder, flour, salt, and baking powder. Gradually add this mixture to the wet ingredients, stirring until just combined.
Step 4: Bake the Brownies
Pour the brownie batter into the prepared baking pan. Bake for about 20–25 minutes or until a toothpick inserted comes out clean. Once baked, let them cool completely before adding the mousse topping.
Step 5: Prepare the Chocolate Mousse
In a saucepan over low heat, melt 8 oz of chopped semisweet chocolate with milk until smooth. Remove from heat and allow to cool slightly. In another bowl, whip 1 1/2 cups of heavy cream until soft peaks form. Fold in the melted chocolate gently until combined.
Step 6: Assemble Your Dessert
Spread the mousse evenly over the cooled brownies. Chill in the refrigerator for at least three hours to set before serving.

Common Mistakes to Avoid
To make your Chocolate Mousse Brownies Recipe a success, avoid these common pitfalls.
- Skipping the chilling step: Chilling the chocolate mixture is essential for the right mousse texture. Always allow it to cool before combining with whipped cream.
- Using warm ingredients: Make sure all ingredients, especially the chocolate, are at room temperature. Warm ingredients can lead to a runny consistency.
- Overmixing the batter: When combining the brownie ingredients, mix just until combined. Overmixing can make the brownies tough.
- Not measuring accurately: Baking is a science; use precise measurements for best results. Invest in a kitchen scale if necessary.
- Ignoring baking time: Keep an eye on the baking time. Overbaking will result in dry brownies, while underbaking may leave them too gooey.
