Instructions

  1. 1. Line an 8-inch (20 cm) square pan or silicone bar mold with parchment paper.
  2. 2. Mix the cookie crumbs, melted butter, melted white chocolate, and sea salt until evenly combined. Press firmly into the pan and refrigerate for 20 minutes.
  3. 3. Bloom the gelatin in the cold water for 5 minutes.
  4. 4. Heat the milk until just steaming and stir in the bloomed gelatin until completely dissolved. Pour over the white chocolate and stir until smooth.
  5. 5. Beat together the cream cheese, mascarpone, blueberry purée, vanilla bean paste, and lemon juice until silky. Stir in the white chocolate mixture.
  6. 6. Whip the heavy cream to soft peaks and gently fold it into the blueberry mixture to create a light mousse.
  7. 7. In a separate bowl, whisk together the mascarpone, heavy cream, condensed milk, and vanilla bean paste until smooth. Spread into a thin square on parchment and freeze until firm.
  8. 8. Spread half of the blueberry mousse over the chilled cookie base. Place the frozen vanilla cream layer on top, then cover with the remaining mousse. Freeze for at least 6 hours or overnight.
  9. 9. Bloom the remaining gelatin for the mirror glaze. Heat the water, sugar, and condensed milk until the sugar dissolves. Remove from the heat, stir in the gelatin, then pour over the white chocolate and blend until smooth.
  10. 10. Tint the glaze with deep blue and a touch of violet gel coloring. Mix in the pearl luster dust and cool the glaze to 90°F (32°C).
  11. 11. Remove the frozen dessert from the mold and place it on a wire rack. Pour the mirror glaze evenly over the top and sides until completely coated.
  12. 12. Let the glaze set for 10–15 minutes, then slice into bars with a warm knife. Garnish with fresh blueberries, white chocolate curls, edible silver leaf, freeze-dried blueberry powder, and edible flowers before serving.

Notes

Freeze the bars for at least 6 hours or overnight to ensure clean slicing. The glaze should be at 90°F (32°C) for best pouring consistency.
