Preheat the oven to 375°F. Line a 9×13-inch baking sheet with parchment paper.
Make the cream cheese filling: beat the cream cheese, granulated sugar and egg together until smooth.
Next, prepare the puff pastry: unroll the dough and cut out heart shapes using a large heart-shaped cookie cutter.
Place the whole heart cutouts onto a baking sheet lined with baking parchment. Spoon or pipe the cheesecake filling into the center of each pastry.
Bake the puff pastry hearts for 18-20 minutes or until puffed up and golden brown. Remove them from the oven and let them cool slightly.
While the puff pastries cool, slice each strawberry in half and then use a smaller heart-shaped cutter to create heart-shaped strawberries. Make as many heart-shaped strawberries as you have puff pastries.
Once the pastries have cooled slightly, place a heart strawberry in the center of each pastry.
Dust the pastries with powdered sugar before serving.
Serve your cream cheese heart puff pastries warm or at room temperature.
