First, if the pie crusts are frozen, thaw them per the directions on the package.
Roll out the pie dough on a lightly floured surface and using a cookie cutter cut out 4 4-inch circles from each crust. Discard the scraps or roll them to make more hand pies. Or make smaller pies.
Add 2 tablespoons of pumpkin pie filling to the circles leaving about a ½-inch border.
Next, dip a fingertip into some water and run it around the edges of the circles.
Fold the crust over the filling to create a half-moon shape and gently pinch the edges together. Using a fork crimp the edges together.
In a small bowl, whisk the egg with the water and brush the mixture all over the pies.
Mix the cinnamon with the sugar and sprinkle on top of the pies.
Make 3 small incision cuts on the top.
Preheat the air fryer to 360 degrees F.
Spray the basket with oil spray. Arrange the pies, in one single layer not touching each other, you may need to cook these in batches.
Air fry for 9-10 minutes, or until golden brown.
