Creating the Lemon Blueberry Cream Cheese Danish can be effortless when you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Roll Out Puff Pastry: On a floured surface, roll out the thawed puff pastry to smooth out any creases. Cut the pastry into squares or rectangles, about 4-5 inches on each side.
3. Make Cream Cheese Filling: In a mixing bowl, combine softened cream cheese, granulated sugar, lemon juice, lemon zest, and one egg. Mix until well blended and smooth.
4. Assemble the Danish: Place a tablespoon of cream cheese filling in the center of each pastry square. Top with a spoonful of blueberry filling.
5. Fold the Pastry: Fold the corners of the pastry over the filling to create a diamond shape. Pinch the edges to seal them tightly.
6. Prepare Egg Wash: Beat the remaining egg in a small bowl and brush the tops of each danish lightly with the egg wash for a golden finish.
7. Bake: Place the danishes on the prepared baking sheet and bake in the preheated oven for 15-20 minutes or until golden brown and puffed.
8. Cool: Remove from the oven and let the danishes cool on a wire rack for about 30 minutes.
9. Dust with Powdered Sugar: Before serving, dust the tops of the cooled danishes with powdered sugar to enhance the presentation.

Following these steps closely will lead you to an incredible outcome, ensuring your Lemon Blueberry Cream Cheese Danish turns out perfectly delicious.
