Ingredients

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

Chocolate Mousse

  • 1 cup heavy cream
  • 8 ounces semi-sweet chocolate, chopped
  • 3 large egg whites
  • 1/4 cup granulated sugar
  • 1 teaspoon vanilla extract

Gather all your ingredients before starting to ensure a smooth baking process.

Instructions

Prepare the Brownie Base

Preheat your oven to 350°F (175°C). Grease and line a 9x13 inch baking pan with parchment paper.

In a large bowl, melt the butter and stir in sugar, eggs, and vanilla. Mix until well combined. Add flour, cocoa powder, and salt, stirring until just combined. Pour the batter into the prepared pan and spread evenly.

Bake for 25 minutes, then let cool completely.

Make the Chocolate Mousse

In a heatproof bowl, melt the chopped chocolate over a pot of simmering water, stirring until smooth. Let cool slightly.

In a separate bowl, whip the heavy cream until soft peaks form. In another bowl, beat the egg whites until soft peaks form, then gradually add sugar and beat until stiff peaks form.

Fold the melted chocolate into the whipped cream, then gently fold in the egg whites until fully incorporated.

Assemble the Layers

Pour the mousse over the cooled brownie base, spreading it evenly. Refrigerate for at least 2 hours or until set.

Once set, slice into squares and serve chilled.

Enjoy your delicious Chocolate Mousse Brownies!

Storage Tips

To store leftover Chocolate Mousse Brownies, cover them tightly with plastic wrap or transfer them to an airtight container. They can be kept in the refrigerator for up to a week, maintaining their delicious flavor and texture. If you notice any separation in the mousse after a few days, simply give it a gentle stir before serving.

For longer storage, you can freeze the brownies. Cut them into squares, wrap each piece in plastic wrap, and then place them in a freezer-safe container. They can last up to three months in the freezer. Thaw them in the refrigerator overnight before enjoying, and they'll taste just as decadent as the day they were made.

Serving Suggestions

Enhance your Chocolate Mousse Brownies by serving them with a dollop of whipped cream or a scoop of vanilla ice cream on the side. The creaminess of the ice cream beautifully complements the rich chocolate and adds an extra layer of indulgence to the dessert. For a touch of elegance, consider garnishing with fresh berries or a sprinkle of cocoa powder.

If you want to impress your guests even more, drizzle a homemade chocolate sauce or caramel over the top just before serving. This not only adds visual appeal but also enhances the overall flavor, making your dessert experience even more indulgent.
