  • 1 1/2 cups heavy cream

  2. In a bowl, beat the cream cheese with sugar and vanilla extract until smooth.
  3. Add the melted white chocolate and ground pistachios. Mix until combined.
  4. Heat the bloomed gelatin gently until fully dissolved, then stir it into the pistachio mixture.
  5. Whip the heavy cream to soft peaks, then gently fold it into the pistachio mixture to create a mousse.
  6. Place the red velvet cake layer into the bottom of a springform pan or cake ring.
  7. Spread half of the pistachio mousse over the cake layer and smooth the top.
  8. Add a layer of fresh berries, then spread the remaining mousse over the berries and level the top.
  9. Chill the cake in the refrigerator for at least 4 hours or overnight until set.
  10. Once set, top with additional fresh berries, chopped pistachios, and a light glaze if desired.
  11. Slice and serve chilled for an elegant presentation.

Notes

  • Ensure gelatin is fully dissolved to avoid lumps in the mousse.
  • You can use store-bought red velvet cake or homemade.
  • A glaze helps preserve the fruit and adds shine but is optional.
