Ingredients

For the Brownie Base:

• 1/2 cup unsalted butter, melted

• 1 cup granulated sugar

• 2 large eggs

• 1 teaspoon vanilla extract

• 1/2 cup all-purpose flour

• 1/3 cup cocoa powder

• 1/4 teaspoon salt

• 1/2 teaspoon baking powder

• 1/4 cup chocolate chips (optional for extra fudginess)

• 2 tablespoons powdered sugar (optional, for sweetness)

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

Directions

For the Brownie Base:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease an 8×8-inch baking dish or line it with parchment paper.

2. Prepare the Brownie Batter: In a mixing bowl, whisk together the melted butter and granulated sugar until smooth. Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.

3. Add the Dry Ingredients: Sift the flour, cocoa powder, salt, and baking powder into the bowl and stir until just combined. If using, fold in the chocolate chips.

4. Bake the Brownies: Pour the brownie batter into the prepared baking dish and spread it out evenly. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out mostly clean (a few moist crumbs are fine). Let the brownies cool in the pan for about 10 minutes, then transfer them to a wire rack to cool completely.

For the Chocolate Mousse:

5. Prepare the Mousse: In a medium saucepan, heat the heavy cream over medium heat until it begins to simmer. Remove from the heat and add the chocolate chips. Stir until the chocolate is completely melted and the mixture is smooth.

6. Cool the Mousse: Let the chocolate mixture cool for about 10 minutes, then add the vanilla extract and powdered sugar (if using) and mix until smooth.

7. Chill the Mousse: Allow the mousse mixture to cool to room temperature, then place it in the refrigerator for about 30 minutes to firm up slightly. After it’s chilled, use a hand mixer or stand mixer to whip the mousse for 2-3 minutes, until it becomes light and fluffy.

Assembling the Brownies:

8. Top the Brownies: Once the brownies have cooled completely, spread the chocolate mousse evenly on top of the brownies.

9. Chill and Set: Place the brownies with mousse in the refrigerator for at least 1-2 hours to allow the mousse to set and the flavors to meld together.

10. Serve: Once the mousse is set, cut the brownies into squares and serve. Enjoy!

Variations

FAQs

1. Can I make the brownies ahead of time?

Yes, you can make the brownies a day ahead of time and refrigerate them. Just add the mousse topping when you’re ready to serve.

2. Can I use a different type of chocolate for the mousse?

Absolutely! You can use dark chocolate, milk chocolate, or even white chocolate for the mousse, depending on your taste preferences.

3. Can I make this dessert without heavy cream?

For a lighter mousse, you can use coconut cream or a non-dairy alternative like almond milk, though the texture may be slightly different.

4. Can I freeze these brownies?

Yes, you can freeze the brownies (without the mousse) for up to 3 months. Allow them to cool completely before wrapping in plastic wrap and freezing. When ready to serve, let them thaw and top with freshly made mousse.

5. How can I make the mousse firmer?

If you prefer a firmer mousse, you can add a little gelatin to the cream mixture before cooling it, or reduce the amount of heavy cream.

6. How do I know when the brownie base is done?

The brownie base is done when a toothpick inserted into the center comes out with only a few moist crumbs (not wet batter). The brownies will continue to firm up as they cool.

7. Can I make the mousse without whipping it?

While whipping the mousse makes it lighter and fluffier, you can skip this step if you prefer a denser mousse texture. Just ensure the mixture is smooth and fully cooled before spreading on the brownies.

8. Can I make these brownies gluten-free?

Yes, you can make these brownies gluten-free by using a gluten-free all-purpose flour blend in place of the regular flour.

9. Can I use a different pan size for baking the brownies?

If you use a different pan size, adjust the baking time accordingly. A larger pan will make thinner brownies, while a smaller pan will make thicker brownies and may require a longer bake time.

10. How do I prevent the mousse from separating from the brownies?

Make sure the mousse is chilled and whipped to the right consistency before spreading it on the brownies. Allow the mousse to set in the fridge for at least 1 hour to prevent it from separating.
