Preheat the oven to 400°F (200°C).

Roll out the puff pastry sheet on a lightly floured surface.

Cut the pastry into 4 equal squares and place them on a baking sheet lined with parchment paper.

Bake in the preheated oven for 15 minutes or until golden brown.

In a mixing bowl, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form.

Gently fold in the sliced strawberries.

Once the pastries are cool, cut them in half horizontally.

Spoon the strawberry and cream mixture onto the bottom half of each pastry and replace the top half.

Dust with powdered sugar before serving.
