Step-by-Step Preparation for Chocolate Mousse Brownies

Start by preheating your oven to 350°F (175°C) and lining a 9×13 pan with parchment, leaving overhang for easy removal. In a bowl, melt the butter and let it cool slightly. Whisk in the sugar, then beat in the eggs one at a time, followed by the vanilla. In another bowl, sift flour, cocoa, and salt. Gently fold into the wet mixture until just combined. Spread into the pan and bake 25–30 minutes, until a toothpick comes out with moist crumbs. Cool completely.

For the mousse, heat the cream just to simmering. Remove from heat and add chocolate, stirring until smooth. In another bowl, whisk yolks and sugar until pale. Gradually whisk in some warm chocolate to temper, then pour back into saucepan. Cook over low heat, stirring, until slightly thickened. Remove from heat, stir in vanilla, and let cool. Whip an additional 1/2 cup cream to stiff peaks and fold gently into chocolate. Spread over cooled brownies, chill at least 2 hours.
