Preheat your oven to 400°F (200°C).

In a mixing bowl, blend softened cream cheese, powdered sugar, and vanilla extract until creamy and smooth. Refrigerate until ready to use.

Dice strawberries into small chunks and set aside.

Flour your surface and roll out the puff pastry into an 11-inch square. Cut into 4 equal squares.

Whisk together the egg and water in a small bowl to create an egg wash. Brush the egg wash lightly over each pastry square.

Fold each pastry square into a triangle, brush the tops with egg wash, and place on a parchment-lined baking sheet.

Bake for about 18 minutes or until puffed and golden brown.

Let cool before carefully opening the pastries with a serrated knife.

Fill each turnover with a layer of cream cheese mixture and diced strawberries. Dust with powdered sugar before serving.
