Cut puff pastry into 4 squares.
Spray muffin tins with cooking spray.
Add one puff pastry square to each muffin tin.
Add apple pie filling. (I ran my knife through them to cut the slices into smaller pieces.)
Fold the puff pastry into the middle.
Brush with egg wash and then sprinkle raw sugar on top.
Bake on 400 degrees for 20-25 minutes.
