For the Brownie Base:
- 1 box fudge brownie mix (18.3 oz), plus ingredients required on the box
(or make your favorite from-scratch brownie base)
For the Chocolate Mousse Topping:
- 1½ cups (355 ml) heavy whipping cream

- 1 (8 oz) package cream cheese, softened
- ¾ cup (90 g) powdered sugar

Step-by-Step Instructions for Chocolate Mousse Brownies
1. Bake the brownie base
Prepare your brownie mix according to package instructions and bake in a 9×13-inch pan. Let cool completely.
2. Make the chocolate ganache
In a microwave-safe bowl, melt the chocolate chips with ½ cup of the heavy cream. Stir until smooth and let cool slightly.
3. Beat cream cheese mixture
In a mixing bowl, beat softened cream cheese, powdered sugar, and vanilla extract until light and fluffy.
4. Add ganache to cream cheese
Pour the cooled ganache into the cream cheese mixture and beat until fully incorporated.
5. Whip remaining cream
In a separate bowl, whip the remaining 1 cup of heavy cream to stiff peaks.
6. Fold whipped cream into mousse
Gently fold the whipped cream into the chocolate-cream cheese mixture. Do not overmix—this keeps the mousse light.
7. Assemble
Spread the mousse evenly over the cooled brownies. Use an offset spatula for a smooth finish.
8. Chill and serve
Refrigerate for at least 2 hours before slicing. Serve chilled and top with your favorite garnish.
This process creates a smooth mousse layer that holds its shape but melts in your mouth—ideal for easy fast dessert prep.
