- 1/2 cup butter, melted
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
- 1/2 cup heavy cream
- 8 oz semi-sweet chocolate, chopped

How to Serve Chocolate Mousse Brownies
Serve the Chocolate Mousse Brownies chilled. They are delightful on their own, but you can also add a scoop of vanilla ice cream or some fresh berries for a refreshing touch. A sprinkle of chocolate shavings on top adds an elegant finish and extra chocolate flavor.
How to Store Chocolate Mousse Brownies
Store any leftover brownies in an airtight container in the refrigerator. They should be good for up to 3-4 days. If you want them to last longer, you can freeze them without the mousse for up to a month. Just thaw and then add the mousse before serving.
Tips to Make Chocolate Mousse Brownies
- Make sure your butter is completely melted to ensure a smooth batter.
- Do not overmix once you add the flour, as this can make the brownies tough.
- Allow the brownies to cool completely before adding the mousse to prevent it from melting.
- Whip the heavy cream until soft peaks form for the perfect mousse consistency.
Variation
For a different twist, you can add nuts like walnuts or pecans into the brownie batter before baking. You can also substitute the semi-sweet chocolate with dark chocolate for a richer taste.
