What you will need

This recipe uses 5 simple ingredients that you can find at any grocery store:

  • 1 sheet store-bought puff pastry thawed
  • 1 cup fresh or frozen blueberries
  • 2 tbsp sugar
  • 1 tbsp cornstarch
  • 1 tbsp powdered sugar for dusting

Step by step instructions

Step 1: Prep Pastry and Filling

Preheat oven to 425 degrees F. Cut puff pastry sheet into 4 equal squares. In a small bowl toss blueberries with sugar and cornstarch until coated.

Step 2: Assemble and Bake

Place pastry squares on a parchment-lined baking sheet. Spoon blueberry mixture into the center of each square leaving a border. Fold edges up slightly and bake for 10 to 12 minutes until golden and puffed.

Step 3: Finish and Serve

Remove from oven and let cool for 2 minutes. Dust with powdered sugar and serve warm for the best flaky and gooey texture.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • blueberries → raspberries sliced strawberries or cherries
  • puff pastry → crescent roll dough for a softer result

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Not leaving enough border on the pastry which causes the filling to spill and burn
  • Using too much filling which weighs down the pastry and prevents it from puffing properly
