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

1. Preheat Oven: Preheat 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 sheet on a lightly floured surface. Cut it into a rectangle about 12×8 inches.
3. Make Cream Cheese Filling: In a bowl, combine the softened cream cheese, powdered sugar, and vanilla extract. Mix until smooth and creamy.
4. Prepare Strawberries: In another bowl, toss the sliced strawberries with granulated sugar and cornstarch. This will help thicken the juices.
5. Assemble Danish: Place the cream cheese mixture in the center of the puff pastry, spreading it evenly. Layer the sweetened strawberries on top of the cream cheese.
6. Fold Edges: Fold the edges of the pastry over the filling, creating a border. Pinch the corners to seal.
7. Make Egg Wash: In a small bowl, whisk together the egg and milk. Brush this mixture over the pastry edges for a golden finish.
8. Bake: Place the assembled Danish on the prepared baking sheet. Bake in the preheated oven for 25-30 minutes, or until the pastry is golden brown and puffed.
9. Cool: Once baked, remove from the oven and let cool on the baking sheet for about 10-15 minutes.
10. Serve: Dust with additional powdered sugar, if desired, before serving.

By following these steps, you’ll create a Strawberry Danish that is not only delicious but also visually appealing!
