Making Blueberry Cream Cheese Puff Pastry can be simple if you follow these straightforward steps:

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. Prepare Puff Pastry: On a lightly floured surface, roll out the thawed puff pastry sheets. Cut into squares approximately 4 inches by 4 inches.
3. Make the Filling: In a mixing bowl, combine softened cream cheese, granulated sugar, and vanilla extract. Mix until smooth and creamy.
4. Add Blueberries: Gently fold in the fresh blueberries, taking care not to crush them.
5. Assemble the Pastries: Place a generous spoonful of the cream cheese filling in the center of each pastry square. Be careful not to overfill.
6. Seal the Pastries: Fold the pastry over to create a triangle shape, sealing the edges by pressing down with a fork.
7. Apply Egg Wash: Brush the tops of the pastries with the beaten egg for a glossy finish.
8. Bake: Place the pastries on the prepared baking sheet and bake for 25–30 minutes, or until golden brown.
9. Cool Down: Remove from the oven and allow to cool for 5–10 minutes on a wire rack.
10. Dust with Powdered Sugar: For a final touch, sprinkle powdered sugar over the top before serving, if desired.

These steps make creating Blueberry Cream Cheese Puff Pastry both manageable and enjoyable. You’ll find that the delightful aroma wafting through your kitchen will be almost as rewarding as the final product!
