Let’s Make it Together
Prepare yourself for a delicious adventure as we dive into creating these Layered Chocolate Mousse Brownies!
Bake the Brownie Base: Preheat your oven to 350°F (175°C). Grease an 8-inch square baking pan with nonstick spray or line it with parchment paper for easy removal. In a medium bowl, melt butter and dark chocolate together until smooth and glossy.
Mix Dry Ingredients: In another bowl, whisk together cocoa powder, flour, granulated sugar, and salt until combined. This ensures an even distribution of flavors throughout our brownie base.
Add Wet Ingredients: Stir in eggs one at a time into the melted chocolate mixture until fully incorporated. Add vanilla extract nextâthis will make everything smell heavenly!
Combine Mixtures: Gradually fold the dry ingredients into the wet mixture using a spatula until just combinedâdonât overmix! Pour this luscious batter into your prepared baking pan.
Bake to Perfection: Bake in preheated oven for about 25-30 minutes until set around edges but slightly soft in centerâtrust me; they’ll firm up while cooling! Allow cooling completely before adding mousse layer.
Create the Mousse: While brownies cool down, whip heavy cream until soft peaks form in a chilled bowlâthis helps achieve that lightness we adore. In another bowl, melt dark chocolate and let it cool slightly before folding it into whipped cream gently.
Spoon on Mousse: Spread this velvety chocolate mousse over cooled brownies evenlyâget creative with swirls if you’re feeling fancy! Chill in refrigerator for at least two hours before slicingâtheyâre worth the wait!
Now sit back and watch as your friends swoon over every bite of these decadent Layered Chocolate Mousse Brownies! Theyâll beg you for seconds⌠or thirds!
