Making Blackberry Cream Cheese Danish can be a seamless process when you follow these steps:

1. Preheat the Oven: Set your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare Puff Pastry: Roll out the thawed puff pastry sheets on a lightly floured surface. Cut each sheet into desired squares or rectangles.
3. Make the Filling: In a mixing bowl, combine the softened cream cheese, granulated sugar, and vanilla extract. Blend until smooth and creamy.
4. Prepare Blackberries: In another bowl, toss the fresh blackberries with flour to coat them lightly. This will help thicken any juices that may leak out during baking.
5. Fill the Pastry: Place a spoonful of cream cheese filling in the center of each pastry square. Top it with a few blackberries.
6. Fold and Seal: Bring the corners of the pastry over the filling to form a pocket. Pinch the seams to seal them well.
7. Egg Wash: Beat the egg and brush it gently over the top of each Danish for a beautiful golden finish.
8. Bake: Place the prepared pastries on the lined baking sheet and bake for 20-25 minutes or until golden brown and puffed up.
9. Cool: Remove from the oven and allow them to cool slightly on a wire rack.
10. Optional Dusting: If desired, dust the top with powdered sugar before serving.

By following these detailed instructions, you’ll create perfectly flaky and flavorful Blackberry Cream Cheese Danish that will leave everyone wanting more!
