Instructions

1. Step 1: Place 1 tsp gelatin powder in 2 tbsp cold water and let bloom for 5 minutes.
2. Step 2: Heat 1 cup heavy cream with 1/4 cup granulated sugar in a saucepan over medium heat until it just begins to simmer; remove from heat.
3. Step 3: Whisk 4 egg yolks in a bowl, then slowly pour the hot cream mixture into the yolks while whisking continuously to temper them. Return the mixture to the saucepan and cook over low heat, stirring constantly until it thickens enough to coat the back of a spoon, about 3-4 minutes.
4. Step 4: Remove from heat, add softened 2 tbsp unsalted butter and bloomed gelatin, stirring until fully melted. Divide the custard evenly into two bowls.
5. Step 5: Melt 6 oz chopped dark chocolate in one bowl and 6 oz milk chocolate in the other, stirring each until smooth. Add 1/2 tsp vanilla extract into each bowl and mix well.
6. Step 6: Whip the remaining 2 cups heavy cream to soft peaks. Fold half the whipped cream into the dark chocolate custard gently until incorporated, then repeat with the milk chocolate custard.
7. Step 7: Line a 6-inch high cake ring with acetate or parchment. Pour the dark chocolate mousse evenly, smoothing the top, then refrigerate for 30 minutes to set.
8. Step 8: Pour the milk chocolate mousse on top of the set dark layer, smooth the surface, and chill for at least 4 hours or overnight.
9. Step 9: Remove the cake ring and dust the top with 2 tbsp cocoa powder before serving to showcase the high, layered effect.
