Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Roll out 2 puff pastry sheets to fit two 9x12 inch baking trays. Place each sheet on parchment-lined trays, prick all over with a fork, and bake for 15-18 minutes until golden and crisp. Set aside to cool.
  2. Step 2: In a medium saucepan, whisk together 3/4 cup granulated sugar and 1/4 cup cornstarch. Gradually whisk in 2 cups whole milk until smooth. Add 4 egg yolks and 1 tsp vanilla bean paste, whisking constantly.
  3. Step 3: Cook the mixture over medium heat, stirring continuously until it thickens and comes to a boil, about 5-7 minutes. Remove from heat and stir in 2 tbsp unsalted butter until melted and smooth. Pour custard into a bowl, cover surface directly with plastic wrap, and chill for 1 hour.
  4. Step 4: To make the glaze, whisk 1 cup powdered sugar with 3 tbsp passionfruit pulp and 1 tbsp lemon juice until smooth.
  5. Step 5: To assemble, place one puff pastry sheet on a serving tray. Spread the chilled custard evenly over it, then top with the second puff pastry sheet. Pour the passionfruit glaze over the top and refrigerate for 30 minutes before slicing and serving.
