Ingredients
- 8-inch round sponge cake base, store-bought or homemade
- 2 tbsp matcha powder
- 1/4 cup hot water
- 3 sheets gelatin sheets
- 1/2 cup granulated sugar
- 2 cups heavy cream
- 6 oz white chocolate, chopped
- 1 tsp vanilla extract
Instructions
- Step 1: Soak 3 gelatin sheets in cold water for 5 minutes. In a small bowl, whisk 2 tbsp matcha powder with 1/4 cup hot water until smooth and no lumps remain.
- Step 2: Heat 1/4 cup heavy cream in a small saucepan until just simmering. Remove from heat and stir in soaked gelatin (squeeze out excess water) until dissolved. Mix in matcha mixture and 1/4 cup granulated sugar until sugar dissolves. Let cool slightly.
- Step 3: Whip 1 cup heavy cream with 1/4 cup granulated sugar and 1 tsp vanilla extract until soft peaks form. Gently fold the matcha gelatin mixture into the whipped cream until combined.
- Step 4: In a separate bowl, melt 6 oz chopped white chocolate over a double boiler until smooth. Heat remaining 3/4 cup heavy cream until simmering and pour over melted white chocolate, stirring until smooth. Soften the remaining gelatin sheet in cold water, melt it in the warm white chocolate mixture, and cool slightly.
- Step 5: Whip remaining 1 cup heavy cream until soft peaks form and fold into the white chocolate mixture.
- Step 6: Place the sponge cake base in a springform pan. Pour the matcha mousse over the base and refrigerate for 1 hour until set. Carefully pour the white chocolate mousse on top and refrigerate for at least 4 more hours until fully set before serving.
