Step 1: Prepare the Puff Pastry

Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper. Roll out the thawed puff pastry sheet on a lightly floured surface and cut it into 6 equal rectangles using a sharp knife or pizza cutter.

Step 2: Prepare the Cream Cheese Filling

In a mixing bowl, beat the softened cream cheese, sugar, vanilla extract, and lemon juice until smooth and creamy.

Step 3: Assemble the Danish

Spoon about 1-2 tablespoons of the cream cheese mixture into the center of each puff pastry rectangle. Fold the edges slightly inward to prevent the filling from spilling out while baking.

Step 4: Apply the Egg Wash

In a small bowl, whisk the egg with 1 tablespoon of water. Brush the edges of the puff pastry with the egg wash to help create a golden, crispy finish.

Step 5: Bake to Perfection

Place the pastries on the prepared baking sheet and bake for 15-18 minutes or until golden brown and puffed up.

Step 6: Drizzle with Glaze (Optional)

Once the danishes have cooled for a few minutes, whisk together the powdered sugar, milk, and vanilla extract to create a smooth glaze. Drizzle over the warm pastries.
