How to Make Chocolate Mousse Brownies

Simple Ingredients
Most of these items are already in your pantry. Using fresh, high-quality chocolate makes a huge difference here.
- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
- 12 ounces semi-sweet chocolate, finely chopped (divided)
- 2 cups heavy whipping cream (divided)
- 2 tablespoons powdered sugar
- 1 teaspoon unflavored gelatin
- 2 tablespoons cold water
Step-by-Step Directions
- Preheat oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides.
- In a medium bowl, whisk together melted butter and granulated sugar until combined. Whisk in eggs and vanilla until smooth.
- Sift cocoa powder, flour, and salt into the wet ingredients; fold gently with a spatula until no dry streaks remain.
- Spread batter evenly into the pan and bake for 22-25 minutes until the center is set. Cool completely in the pan.
- Prepare the mousse stabilizer: Sprinkle gelatin over 2 tablespoons cold water and let bloom for 5 minutes, then microwave for 10 seconds until liquid.
- Melt 8 ounces of chopped chocolate in a heat-proof bowl. Stir in the liquid gelatin until smooth and set aside to cool slightly.
- In a separate chilled bowl, whip 1.5 cups of heavy cream and powdered sugar to stiff peaks.
- Gently fold one-third of the whipped cream into the melted chocolate to lighten the mixture, then fold in the remaining cream until uniform.
- Spread the mousse over the cooled brownie layer and refrigerate for at least 4 hours to set.
- Make the ganache: Heat the remaining 1/2 cup heavy cream until simmering, then pour over the remaining 4 ounces of chopped chocolate.
- Let the ganache sit for 3 minutes, whisk until glossy, pour over the chilled mousse layer, and refrigerate for 30 minutes before slicing.
Best Ways to Enjoy It
Serve these treats in small, elegant squares. A little goes a long way because they are rich. They look beautiful on a simple white dessert plate. Pair a square with a hot cup of coffee. For a romantic date night, add a few fresh raspberries.
Keep It Fresh
Keep any leftovers in the refrigerator at all times. The mousse needs to stay cool to hold its shape. Cover the pan tightly with plastic wrap or foil. These brownies will stay fresh for up to five days. Enjoy them cold for the best texture and flavor.
Tips for Best Results
- Use high-quality semi-sweet chocolate for the best flavor.
- Don’t skip the parchment paper for easy removal.
- Avoid over-mixing the brownie batter to keep it fudgy.
- Let the melted chocolate cool slightly before adding whipped cream.
- For the holidays, add a crush of candy canes on top.
- Wipe your knife between slices for clean, professional edges.
- Make sure your heavy cream is very cold before whipping.
Ways to Switch It Up
- Swap all-purpose flour for a gluten-free blend if needed.
- Add peppermint extract to the mousse for a winter twist.
- Use dark chocolate instead of semi-sweet for a deeper flavor.
- Top with sea salt for a salty and sweet balance.
Common Questions
Can I make these brownies ahead of time?
Yes, you definitely should make them ahead. They need at least four hours to set properly. Making them the night before is even better. This allows the flavors to meld together beautifully.
How do I know when the brownies are done?
The center should be set but still look soft. Do not overbake them or they will be dry. A toothpick should come out with a few moist crumbs. They will continue to firm up as they cool.
Will kids enjoy these layered brownies?
Kids absolutely love the creamy mousse layer. It tastes like a chocolate cloud on a brownie. It is a fun and fancy treat for the whole family. They are always a hit at holiday gatherings.
I hope these decadent treats bring a little joy to your kitchen. They are the perfect way to celebrate a cozy winter evening. Give them a try and enjoy every chocolatey bite.
