Prepare the Strawberry Topping : In a bowl, mix the sliced strawberries, cornstarch, and sugar. Set aside to allow the juices to combine and thicken slightly.
Make the Cream Cheese Filling : Beat the cream cheese with powdered sugar and vanilla extract in a medium bowl until smooth and creamy.
Prepare the Puff Pastry : Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper. On a lightly floured surface, unfold the thawed puff pastry sheets. Cut each sheet into six equal rectangles.
Assemble the Danish Pastries : Place the pastry rectangles on the prepared baking sheet. Use a knife to gently score a border around each rectangle, about ½ inch from the edge. Inside the scored area, spread a tablespoon of the cream cheese filling. Top with a generous spoonful of the strawberry mixture.
Add the Egg Wash : Lightly brush the edges of each pastry with the egg wash to ensure a golden-brown finish. Sprinkle sugar over the edges if desired.
Bake : Bake for 20–25 minutes, or until the puff pastry is golden brown and the strawberries are bubbling. Remove from the oven and let cool slightly.
Add the Optional Toppings : For a glossy finish, warm the strawberry jam in the microwave and brush it over the strawberries. To make the glaze, whisk together powdered sugar, vanilla extract, and milk. Drizzle over the cooled pastries for an extra touch of sweetness.
Serve and Enjoy : Serve your Strawberry Delight Danish Pastries warm or at room temperature. Pair with coffee or tea for the ultimate treat!
