Ingredients
- 2 sheets puff pastry, thawed
- 1 cup fresh blueberries
- 1 cup whole milk
- 3 egg yolks
- 1/4 cup granulated sugar
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
- 1 tablespoon unsalted butter
- 1 egg, beaten (for egg wash)
- 2 tablespoons powdered sugar (optional, for garnish)
Instructions
- Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
- In a saucepan, whisk together the egg yolks, granulated sugar, cornstarch, and milk until smooth.
- Cook over medium heat, stirring constantly, until the mixture thickens into a smooth custard.
- Remove the custard from the heat and stir in the vanilla extract and butter until fully incorporated.
- Transfer the custard to a bowl and allow it to cool for about 15 minutes.
- Cut each puff pastry sheet into 4 equal squares to make 8 pastries.
- Lightly score a border about 1/2 inch from the edge of each square without cutting all the way through.
- Spoon approximately 2 tablespoons of cooled custard into the center of each pastry square.
- Scatter fresh blueberries evenly over the custard filling.
- Brush the pastry borders with the beaten egg wash.
- Bake for 15 to 20 minutes, or until the pastries are puffed and golden brown.
- Allow the pastries to cool slightly before dusting with powdered sugar if desired.
- Serve warm or at room temperature.
Notes
- Keep puff pastry cold until ready to use for the flakiest results.
- Frozen blueberries may be used without thawing.
- Add 1 teaspoon of lemon zest to the custard for extra brightness.
- Use almond extract along with vanilla for a richer bakery-style flavor.
- Drizzle cooled pastries with a simple vanilla glaze for added sweetness.
- Custard can be prepared up to 1 day in advance and refrigerated.
- Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheat in a 325°F (165°C) oven for 5 to 8 minutes to restore crispness.
- Baked pastries can be frozen for up to 2 months.
