Preheat your oven to 400°F and line a baking sheet with parchment paper.
Roll out the puff pastry sheets on a lightly floured surface. Cut the pastry sheets into squares or rectangles (about 3x3 inches).
Spoon the apple filling onto the center of each puff pastry square, leaving space around the edges
Place a second puff pastry square on top of the filling, and using a fork, press the edges of the top and bottom sheets together to seal the pies. Make a 1-inch L shape incision into each pie and fold back the pastry flap.
Beat the egg in a small bowl and brush the tops of the pies with the egg wash, then sprinkle each pie with a little granulated sugar.
Transfer the pies to an ungreased cookie or baking sheet and bake for 18–20 minutes or until the pastry is puffed and golden brown.
Let the pies cool slightly before serving. Enjoy them warm or at room temperature.
