How to Make Chocolate Mousse Brownies
Preheat your oven to 325 °F. This temperature ensures a perfect baking environment for your brownies, giving them a nice, fudgy texture.
Prepare your baking pan by placing parchment paper inside a 13 9-inch pan and buttering the sides. This will help your brownies come out cleanly later.
Beat the eggs in a mixer fitted with a wire attachment at medium speed until they’re fluffy and light yellow, about 3-4 minutes. Then, add in the sugar and mix to combine.
Combine the remaining brownie ingredients. Add the unsalted butter, cocoa powder, vanilla extract, flour, and kosher salt into the egg mixture, mixing until just combined.
Bake the brownie batter in the prepared pan for 30-35 minutes. Check for doneness by inserting a toothpick; it should come out with only a few moist crumbs.
Cool the brownies on a wire rack in the pan, keeping them intact. This cooling helps enhance their fudginess and makes slicing easier later.
Melt the chocolate. Bring a pot of water to a boil and place a heatproof bowl with your milk chocolate over it, allowing it to melt smoothly.
Bloom the gelatin by mixing it with water in a small bowl. Let it sit for 10 minutes this will help the mousse set perfectly.
Heat 1/2 cup of whipping cream in a saucepan until it reaches a boil. Stir in the bloomed gelatin and mix until fully incorporated, then remove from heat.
Whisk half of the warm cream mixture into the melted chocolate rapidly, ensuring a smooth blend. Then add the rest of the cream and whisk until everything is well mixed and glossy.
Whip the remaining 2 cups of cold whipping cream in a stand mixer until soft peaks form. This will give your mousse its light texture.
Fold the cooled chocolate mixture into the whipped cream gently using a spatula, mixing until you see no streaks and have a luscious mousse.
Layer the mousse on top of your cooled brownies, spreading to level off the top. Refrigerate them overnight or for at least 6 hours for the best results.
Serve by lifting the brownies from the pan using the parchment paper edges. Sprinkle with cocoa powder and cut into square bars, ready for your next gathering!
Optional: Garnish with fresh berries for an extra pop of color and flavor.
