1 package refrigerated puff pastry (2 sheets), thawed according to package directions
1 cup fresh blueberries
2 tablespoons granulated sugar
1 tablespoon cornstarch
2 tablespoons melted butter, unsalted preferred
1 egg, beaten (for egg wash)
1 teaspoon lemon zest (optional)
½ teaspoon vanilla extract (optional)
¼ teaspoon ground cinnamon (optional)
1–2 tablespoons coarse sugar for topping (optional)
½ cup powdered sugar (for optional glaze)
1–2 tablespoons milk or cream (for optional glaze)
¼ cup freeze-dried blueberries, crushed (for optional topping)
Instructions
Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a medium bowl, combine blueberries, granulated sugar, and cornstarch. Gently toss until evenly coated. Add optional lemon zest, vanilla, or cinnamon if using.
On a lightly floured surface, unfold each puff pastry sheet and cut into 6 equal rectangles (12 total).
Arrange half of the rectangles on your prepared baking sheet, spaced about 1 inch apart.
Place 1-2 tablespoons of the blueberry filling in the center of each rectangle, leaving a ½-inch border.
Brush the borders lightly with water or egg wash, then place remaining rectangles on top.
Use a fork to firmly press along all four edges of each pop tart to seal completely.
Poke 4-5 small vents in the top of each pop tart with a toothpick to allow steam to escape.
Brush tops with egg wash and sprinkle with coarse sugar if desired.
Bake for 20-25 minutes until puffed and golden brown.
Remove from oven and cool on the baking sheet for 5 minutes, then transfer to a wire rack.
If adding glaze, whisk together powdered sugar and milk until smooth, then drizzle over cooled pop tarts.
Sprinkle with crushed freeze-dried blueberries if desired.
Notes
For the flakiest results, keep puff pastry cold while working with it.
If using frozen blueberries, don’t thaw them first and add an extra ½ tablespoon cornstarch.
Ensure a tight seal by pressing firmly with a fork around all edges to prevent leakage.
For make-ahead convenience, assemble pop tarts and freeze unbaked for up to 1 month.
