Ingredients

For the Brownie Base:

  • Granulated sugar
  • Large eggs
  • Vanilla extract
  • Unsweetened cocoa powder
  • All-purpose flour
  • Salt
  • Baking powder

For the Chocolate Mousse:

  • Heavy whipping cream (chilled)
  • Semisweet chocolate (finely chopped)
  • Milk
  • Powdered sugar

For the Ganache Topping:

  • Semisweet chocolate (finely chopped)
  • Heavy cream

Variations

  • White Chocolate Mousse Brownies: Swap the semisweet chocolate for white chocolate to create a lighter, more delicate mousse topping for your brownies.
  • Nutty Brownie Base: Add chopped nuts like walnuts or pecans to the brownie base for extra texture and flavor.
  • Flavor Add-ins: For a unique twist, add a dash of espresso powder or a splash of flavored extract like almond or hazelnut to the brownie batter for a deeper flavor profile.
  • Berry Infusion: Layer fresh berries, such as raspberries or strawberries, in between the mousse and ganache for a fruity contrast to the richness of the chocolate.

How to Make the Recipe

Step 1: Make the Brownie Base

Preheat the oven to 350°F (175°C) and grease an 8×8-inch baking pan or line it with parchment paper. In a mixing bowl, combine the melted butter and granulated sugar. Add the eggs, one at a time, mixing well after each addition, followed by the vanilla extract. Sift in the cocoa powder, flour, salt, and baking powder. Stir until the batter is smooth and well combined.

Step 2: Bake the Brownies

Pour the brownie batter into the prepared pan and spread it out evenly. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. Let the brownies cool completely in the pan on a wire rack before adding the mousse layer.

Step 3: Prepare the Chocolate Mousse

In a medium saucepan, heat the milk and semisweet chocolate over low heat, stirring constantly until the chocolate is fully melted and smooth. Remove from heat and allow the chocolate mixture to cool to room temperature.

Meanwhile, beat the chilled heavy cream and powdered sugar together in a separate mixing bowl until soft peaks form. Gently fold the melted chocolate into the whipped cream until fully combined, forming a light, fluffy mousse.

Step 4: Assemble the Layers

Once the brownie base has cooled, spread the chocolate mousse evenly over the brownies using a spatula. Smooth it out to cover the entire surface.

Step 5: Prepare the Ganache Topping

In a small saucepan, heat the heavy cream over medium heat until it begins to simmer. Remove from heat and add the chopped semisweet chocolate. Stir until the chocolate has melted completely, creating a smooth ganache. Allow it to cool slightly before pouring it over the mousse layer. Spread the ganache evenly over the mousse.

Step 6: Chill and Serve

Place the layered brownies in the refrigerator for at least 2 hours, or until the mousse and ganache are set. Once chilled, slice the brownies into squares and serve cold or at room temperature.

Tips for Making the Recipe

  • Proper Cooling: Be sure to allow the brownies to cool completely before adding the mousse layer to prevent it from melting.
  • Chill the Mousse: For a better texture, chill the whipped cream before mixing it with the chocolate to ensure the mousse sets properly.
  • Ganache Consistency: If the ganache is too thick, add a little more warm cream to thin it out. If it’s too thin, let it sit for a few minutes to thicken up before pouring it onto the mousse layer.
  • Sharp Knife for Slicing: To get clean slices, use a sharp knife and wipe it between each cut to keep the layers intact.

How to Serve

These layered chocolate mousse brownies are best served chilled, as the mousse and ganache layers hold their shape better when cold. You can serve them on their own or with a scoop of vanilla ice cream for an extra indulgent treat. Fresh berries on top or a drizzle of chocolate syrup would also make for a beautiful presentation.

Make Ahead and Storage

Storing Leftovers

Store any leftover brownies in an airtight container in the refrigerator for up to 5 days. The chilled mousse and ganache will keep their texture and flavor over time.

Freezing

To freeze these brownies, wrap them individually in plastic wrap and place them in a freezer-safe container. They will keep in the freezer for up to 3 months. Thaw at room temperature for a few hours before serving.

Reheating

While these brownies are best served cold, you can gently reheat them in the microwave for a few seconds if you prefer a warmer dessert. Just be careful not to melt the mousse layer.

FAQs

1. Can I make this recipe in advance?

Yes, this dessert is perfect for making ahead. Assemble the brownies the day before and chill them overnight in the refrigerator.

2. Can I use dark chocolate instead of semisweet chocolate?

Yes, you can substitute dark chocolate for semisweet chocolate if you prefer a richer, more intense chocolate flavor.

3. Can I use a different type of flour for the brownies?

All-purpose flour is recommended for the best texture, but you can try using gluten-free flour if you need a gluten-free version.

4. Can I add nuts to the brownies?

Yes, you can add chopped nuts like walnuts or pecans to the brownie batter for added texture and flavor.

5. Can I make this without the ganache topping?

While the ganache adds a beautiful finish to the brownies, you can skip it and just serve the mousse-covered brownies for a slightly lighter version.

6. How can I make the mousse more stable?

For a more stable mousse, add a small amount of gelatin (dissolved in water) to the melted chocolate before folding it into the whipped cream.

7. Can I use non-dairy cream for the mousse?

Yes, you can use coconut cream or any plant-based whipping cream to make the mousse dairy-free.

8. Can I use a hand mixer instead of whipping the cream by hand?

Yes, using a hand mixer or stand mixer will make whipping the cream quicker and easier.

9. Can I make the brownies without eggs?

You can try substituting eggs with flax eggs or chia eggs for an egg-free version, though the texture may vary slightly.

10. How should I cut the brownies for serving?

Use a sharp knife and wipe it between cuts to get clean slices and keep the layers intact.

Layered Chocolate Mousse Brownies are a showstopper dessert that will impress everyone with their rich flavors and elegant layers.
