# Instructions:

01 - Preheat oven to 350°F (175°C). Prepare an 8-inch springform pan with nonstick spray and parchment paper. Melt chocolate and butter over medium-low heat, stir in sugar. Once slightly cooled, whisk in eggs one at a time and vanilla. Fold in sifted flour, cocoa powder, and salt. Spread in pan and bake 20-25 minutes until just set. Cool completely.
02 - Bloom gelatin in water for 5 minutes. Heat ½ cup cream with sugar until simmering. Pour over chocolate, add gelatin, and stir until smooth. Cool to room temperature. Whip remaining cream to medium-stiff peaks. Fold whipped cream into chocolate mixture and spread over brownie layer. Refrigerate.
03 - Heat cream and butter until just before boiling. Pour over chocolate and stir until smooth. Cool to room temperature, then spread over mousse layer. Refrigerate at least 1 hour until set.
