Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Roll out 2 sheets of thawed puff pastry on a parchment-lined baking tray and prick all over with a fork to prevent puffing. Bake each sheet for 15 minutes until golden and crisp, then cool completely.
  2. Step 2: In a medium saucepan, heat 3 cups whole milk with 1 split vanilla bean pod over medium heat until just simmering, then remove from heat and let infuse for 10 minutes. Remove vanilla bean pod.
  3. Step 3: In a bowl, whisk together 1 cup granulated sugar, 1/3 cup cornstarch, and 4 large egg yolks until smooth.
  4. Step 4: Gradually whisk half of the warm milk into the egg mixture to temper, then pour the mixture back into the saucepan with the remaining milk.
  5. Step 5: Cook over medium heat, whisking constantly until the custard thickens and comes to a boil, about 5 minutes.
  6. Step 6: Remove from heat and whisk in 3 tbsp softened unsalted butter until melted and smooth. Pour custard into a clean bowl, cover surface with plastic wrap to prevent skin forming, and chill until cold, about 2 hours.
  7. Step 7: For the glaze, whisk together 1 cup powdered sugar, 1/4 cup strained passionfruit pulp, and 1 tbsp fresh lemon juice until smooth.
  8. Step 8: To assemble, place one puff pastry sheet on a serving plate, spread the chilled custard evenly over it, then top with the second puff pastry sheet.
  9. Step 9: Spread the passionfruit glaze over the top puff pastry layer and refrigerate the slice for 30 minutes before slicing into squares and serving.
