Ingredients You’ll Need for Chocolate Mousse Brownies
Brownie Layer:
- ½ cup (115 g) unsalted butter, melted
- 1 cup (200 g) granulated sugar
- 2 large eggs, room temperature
- 1 tsp vanilla extract
- ½ cup (50 g) unsweetened cocoa powder
- ½ tsp salt
- ½ cup (65 g) all-purpose flour
Chocolate Mousse Layer:
- 1 cup (170 g) semisweet chocolate, chopped
- 1 cup (240 ml) heavy whipping cream, cold
- 2 tbsp powdered sugar
- 1 tsp vanilla extract
Optional Garnish:
- Shaved chocolate, cocoa powder, or berries
Let’s Make It Together
- Preheat your oven to 325°F (165°C) and line a 9×9-inch pan with parchment paper for easy removal.
- In a mixing bowl, whisk the melted butter and granulated sugar together until glossy and well combined.
- Add the eggs and vanilla extract to the mixture, whisking for about 30–45 seconds until fluffy.
- Gently stir in the cocoa powder and salt until you achieve a smooth batter.
- Fold in the all-purpose flour carefully until just combined, taking care not to overmix.
- Spread the brownie batter evenly in the prepared pan and bake for 25–30 minutes. You want the edges to be set, while the center remains slightly soft.
- Remove from the oven and let cool completely in the pan before adding the mousse layer.
Once the brownies are completely cooled, you can create your creamy mousse layer:
- Melt the chopped semisweet chocolate in a microwave-safe bowl, heating it in short bursts of 20 seconds, stirring in between until smooth.
- In a separate bowl, beat the cold heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form.
- Gently fold the melted chocolate into the whipped cream, being careful not to deflate the mousse.
- Once combined, spread the mousse layer evenly over the cooled brownie base.
- Refrigerate for at least 2 hours to allow the mousse to set properly.
Delicious Variations to Try
- Mint Chocolate Mousse: Add a few drops of peppermint extract to the chocolate mousse for a refreshing twist!
- Nutty Bliss: Fold in some finely chopped nuts, like walnuts or pecans, into the brownie layer for added texture.
- Fruity Flavor: Incorporate a layer of fresh raspberries or strawberries atop the mousse for a tart contrast to the rich chocolate.
- Spiced Delight: Add a pinch of cinnamon or a dash of espresso powder to the brownie batter for a delightful depth of flavor.
Chef Emma’s Helpful Tips
- Make-Ahead Magic: These brownies can be made a day in advance! Just be sure to store them covered in the refrigerator to maintain freshness.
- Ingredient Swaps: If you don’t have semisweet chocolate, dark chocolate works beautifully too. Just keep the balance of flavors in mind.
- Slicing Tips: For perfectly smooth cuts, use a hot knife! Simply run the knife under hot water, dry it, and then slice through the brownies.
- Storage Suggestions: These brownies can last up to a week in the refrigerator, sealed tightly to maintain their delightful texture.
