Ingredients

Gather all the ingredients before starting to ensure a smooth cooking process.

Brownie Base

1 cup unsalted butter
2 cups granulated sugar
4 large eggs
1 teaspoon vanilla extract
1 cup all-purpose flour
1 cup unsweetened cocoa powder
1/2 teaspoon salt

Mousse Layer

1 1/2 cups heavy cream
8 ounces bittersweet chocolate, chopped
3 large egg whites
1/4 cup granulated sugar
1 teaspoon vanilla extract

Make sure all ingredients are at room temperature before mixing.

Instructions

Follow these steps carefully for perfect results.

Prepare the Brownie Base

Preheat the oven to 350°F (175°C). Grease a 9x13 inch baking pan.

In a saucepan, melt butter over low heat. Once melted, remove from heat and stir in sugar, eggs, and vanilla. Mix well.

Add flour, cocoa, and salt. Spread batter in the prepared baking pan.

Bake for 25-30 minutes, or until a toothpick comes out clean. Let cool before adding mousse.

Make the Mousse

In a heatproof bowl, melt the chopped chocolate over simmering water, stirring until smooth. Remove from heat and let it cool slightly.

In a separate bowl, whip the heavy cream until soft peaks form.

In another bowl, whip egg whites until foamy, then gradually add sugar and whip until stiff peaks form. Fold the melted chocolate into the whipped cream, then gently fold in the egg whites.

Assemble the Brownies

Pour the mousse over the cooled brownie base and spread evenly. Refrigerate for at least 2 hours to set.

Once set, slice into squares and serve chilled.

Storing Your Brownies

To keep your Chocolate Mousse Brownies fresh, store them in an airtight container in the refrigerator. They can typically last for about 3-5 days, making them a great option to prepare ahead of time. If you prefer to enjoy them chilled, letting them rest in the fridge enhances the mousse's consistency and flavor.

If you need to store them for an extended period, consider freezing the brownies before adding the mousse. Wrap individual portions securely in plastic wrap and then place them in a freezer-safe container. When you're ready to enjoy them, simply thaw in the refrigerator and add the mousse layer.

Serving Suggestions

To elevate your dessert experience, consider serving these brownies with a dollop of whipped cream or a scoop of vanilla ice cream. These additions contrast beautifully with the rich flavors of the brownies and mousse, making each bite a delightful treat.

For a touch of elegance, you can dust the mousse layer with cocoa powder or garnish it with chocolate shavings. Not only do these finishing touches enhance the presentation, but they also add an extra layer of chocolatey goodness that will leave your guests craving more.
