How to Make This Recipe Easy Peasy

INGREDIENTS

FOR THE BROWNIE BASE:

• 1/2 cup (115g) unsalted butter, melted
• 1 cup (200g) granulated sugar
• 2 large eggs
• 1 tsp vanilla extract
• 1/3 cup (40g) unsweetened cocoa powder
• 1/2 cup (65g) all-purpose flour
• 1/4 tsp salt
• 1/4 tsp baking powder

FOR THE CHOCOLATE MOUSSE:

• 1 1/2 cups (350ml) heavy whipping cream, chilled
• 8 oz (225g) semisweet chocolate, finely chopped
• 3 tbsp (45ml) milk
• 2 tbsp (25g) powdered sugar

FOR THE GANACHE TOPPING:

• 4 oz (115g) semisweet chocolate, finely chopped
• 1/2 cup (120ml) heavy cream

INSTRUCTIONS

1. PREPARE THE PAN: Preheat the oven to 350°F (175°C) and line an 8×8-inch (20×20 cm) square baking pan with parchment paper, leaving a slight overhang on the sides for easy removal.
2. MAKE THE BROWNIE BATTER: In a large bowl, whisk together the melted butter, granulated sugar, eggs, and vanilla extract until smooth and well combined.
3. ADD DRY INGREDIENTS: Sift in the cocoa powder, flour, salt, and baking powder. Gently fold the dry mixture into the wet ingredients just until no streaks remain. Do not overmix.
4. BAKE THE BROWNIE LAYER: Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 20 to 25 minutes until a toothpick inserted into the center comes out with a few moist crumbs. Let the brownie base cool completely in the pan.
5. MAKE THE MOUSSE BASE: Heat the milk in a small saucepan over low heat until just steaming. Pour it over the chopped chocolate in a heatproof bowl. Let it sit undisturbed for 2 minutes, then stir until fully melted and smooth. Let the mixture cool to room temperature.
6. WHIP THE CREAM: In a separate bowl, beat the chilled heavy cream and powdered sugar until soft peaks form.
7. FOLD TO COMBINE: Stir a spoonful of whipped cream into the cooled chocolate mixture to loosen it. Gently fold the remaining whipped cream into the chocolate until fully blended and airy. Avoid deflating the mousse.
8. ASSEMBLE MOUSSE LAYER: Spread the chocolate mousse evenly over the cooled brownie base using a spatula. Refrigerate the pan for at least 2 hours, or until the mousse is set.
9. MAKE THE GANACHE: Place the chopped chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan until it begins to simmer. Pour the hot cream over the chocolate and let sit for 2 to 3 minutes. Stir until smooth and glossy.
10. ADD GANACHE TOPPING: Pour the ganache over the chilled mousse layer and smooth the surface with an offset spatula. Return the pan to the refrigerator for 1 hour, or until the ganache is firm.
11. SLICE AND SERVE: Once fully set, lift the dessert out of the pan using the parchment overhang. Slice with a clean, sharp knife, wiping between cuts for neat edges.

Note: For a more intense chocolate flavor, consider using dark chocolate in place of semisweet chocolate in the mousse.

Health and Flavor Benefits of Ingredients

While indulgent desserts like Chocolate Mousse Brownies are a delightful treat, they also offer a few surprising benefits. Cocoa, for instance, is known for its antioxidant properties, which can boost mood and provide a little heart health support. The unsweetened cocoa powder in our brownies contributes to this, while also giving that rich chocolatey depth we all adore. Meanwhile, the heavy cream not only adds a luxurious texture to the mousse and ganache but also provides essential fats needed for satiety and energy. When you savor these brownies, you’re also getting a tiny dose of happiness-inducing endorphins — a sweet bonus to an already delightful dessert!

Tasty Pairings to Serve with This Easy Peasy Dish

These Chocolate Mousse Brownies shine brightly on their own, but pairing them with a few delightful accompaniments can elevate your dessert experience to new heights. Serve them with a dollop of freshly whipped cream or a scoop of vanilla ice cream for a contrast of temperatures and textures. Fresh berries, like raspberries or strawberries, will cut through the richness with a burst of freshness. For a more decadent touch, drizzle with a raspberry coulis or caramel sauce. And if you’re enjoying these on a cozy evening, a warm cup of coffee or a glass of red wine makes for a perfect companion.

Storage Tips and How to Enjoy Leftovers the Easy Peasy Way

If you find yourself with leftovers — though I doubt you will — these Chocolate Mousse Brownies store beautifully. Keep them in an airtight container in the refrigerator for up to five days. They can also be frozen for up to two months; just wrap them tightly in plastic wrap and place them in a freezer-safe container. When you’re ready to indulge again, thaw them overnight in the refrigerator for the best texture. Enjoy them chilled for a firmer bite, or let them sit at room temperature for 15 minutes to soften slightly and bring out the flavors. Leftovers are a blessing when it comes to these scrumptious brownies!

Home baking is more than just mixing ingredients — it’s about creating moments, sharing smiles, and savoring the love that goes into each recipe. These Chocolate Mousse Brownies are a testament to the joy of baking and sharing with those you love. I hope this recipe brings warmth and sweetness to your home, just as it has to mine.
