Creating a Strawberry Danish is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Prepare the Strawberries: In a bowl, combine the chopped strawberries, granulated sugar, cornstarch, and vanilla extract. Mix well and set aside.
3. Roll Out the Pastry: On a lightly floured surface, roll out the puff pastry sheet to smooth out any creases.
4. Cut the Pastry: Cut the pastry into 4 equal squares. Make sure each square is large enough to hold the filling.
5. Prepare the Cream Cheese Mixture: In a separate bowl, mix the softened cream cheese and powdered sugar until smooth.
6. Assemble the Danish: Place a dollop of the cream cheese mixture in the center of each pastry square. Top with a few spoonfuls of the strawberry mixture.
7. Fold the Pastry: Fold the corners of each pastry towards the center, pinching to seal and create a pocket for the filling.
8. Make the Egg Wash: In a small bowl, whisk together the egg and milk. Brush the mixture over each pastry for a golden finish.
9. Bake: Place the filled pastries on the prepared baking sheet and bake for 25-30 minutes, or until golden brown.
10. Cool: Remove from the oven and allow the Strawberry Danish to cool on a wire rack for 30 minutes.
11. Add Glaze (Optional): If desired, mix powdered sugar with a little milk to create a glaze and drizzle over the cooled pastries.
