Prepare the Ingredients:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
2. Thaw the Pastry: If using frozen puff pastry, ensure it’s fully thawed before beginning.

Make the Cream Cheese Filling:

3. Mix the Filling: In a bowl, combine softened cream cheese, granulated sugar, and vanilla extract. Beat until smooth and creamy.

Prepare the Strawberries:

4. Cook the Strawberries: In a small saucepan, combine diced strawberries and strawberry jam. Heat over low-medium heat, stirring occasionally, until the mixture thickens slightly. For extra thickness, add 1 tablespoon of cornstarch dissolved in 1 tablespoon of water.

Shape the Pastries:

5. Cut Heart Shapes: Roll out the puff pastry on a lightly floured surface and cut out heart shapes using a cookie cutter. Re-roll scraps as needed to make 8 hearts.
6. Create a Border: Use a smaller heart-shaped cutter or a knife to lightly score a smaller heart within each pastry, creating a border.

Assemble the Danishes:

7. Add Cream Cheese Filling: Spoon a dollop of the cream cheese mixture into the center of each pastry, staying within the scored border.
8. Top with Strawberries: Add a spoonful of the strawberry mixture on top of the cream cheese.
9. Brush with Egg Wash: Lightly brush the edges of the pastries with beaten egg to ensure a golden finish.

Bake and Cool:

10. Bake: Place the danishes on the prepared baking sheet and bake for 20-25 minutes, or until the pastry is puffed and golden.
11. Cool and Serve: Allow the danishes to cool slightly before dusting with powdered sugar, if desired.
