(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Make the Brownies:

Preheat the oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper.
In a large bowl, mix the melted butter and sugar until well combined.
Beat in the eggs and vanilla extract until smooth.
Sift together the flour, cocoa powder, salt, and baking powder. Gradually add the dry ingredients to the wet mixture, stirring until smooth and well incorporated.
Pour the brownie batter into the prepared pan and spread it evenly.
Bake for 20–25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Let the brownies cool completely in the pan on a wire rack.

Make the Mousse:

In a saucepan, heat the heavy cream over medium heat until it begins to simmer.
Remove from heat and stir in the chocolate chips until completely melted and smooth.
Stir in the sugar and vanilla extract.
Allow the chocolate mixture to cool for 10–15 minutes. Once cooled, whip the mixture with an electric mixer until it forms soft peaks.
Spread the mousse over the cooled brownies and refrigerate for at least 2 hours, allowing the mousse to set.

FAQs

1. Can I use dark chocolate instead of semi-sweet chocolate chips?

Yes, you can use dark chocolate chips, but the mousse will have a slightly more intense flavor.

2. Can I make this dessert a day ahead?

Absolutely! In fact, it’s even better if made the day before, as the flavors will have time to meld and the mousse will firm up in the fridge.

3. Can I use a different type of sweetener?

You can substitute the granulated sugar with a sugar alternative like coconut sugar, stevia, or a sugar substitute of your choice. Keep in mind that the flavor and texture may vary.

4. Can I make this recipe gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend for a gluten-free version of these brownies.

5. How do I know when the brownies are done baking?

Check for doneness by inserting a toothpick into the center of the brownies. If it comes out with a few moist crumbs, they’re done!

6. Can I use whipped cream instead of making mousse?

You can use whipped cream, but it won’t have the same dense, creamy texture as the mousse made with heavy cream and chocolate.

7. Can I add a layer of fruit to this dessert?

Yes, you can top the brownies with fresh raspberries, strawberries, or even cherries before adding the mousse for a burst of fruity flavor.

8. Can I make this dessert in a larger pan?

Yes, you can use a 9×9-inch or 9×13-inch pan for larger servings, but be sure to adjust the baking time as needed.

9. Can I freeze the brownies?

Yes, you can freeze the brownies before adding the mousse. Wrap them tightly in plastic wrap and freeze for up to 3 months. Thaw overnight before adding the mousse.
