In a medium bowl, mix together 3/4 cup granulated sugar and 3 teaspoons apple pie spice until well blended, then set aside.

Separate the Pillsbury Grands Biscuits and press each one into a 4-inch circle on a clean surface.

In another bowl, combine 1 cup apple pie filling with 1 teaspoon ground cinnamon.

Scoop about 1 tablespoon of filling into the center of the biscuit circle, fold over, and seal tightly.

Preheat air fryer to 350°F, spray basket with cooking spray, place bombs in, and cook for 8-9 minutes, flipping halfway through.

Dip cooked bombs in melted butter and roll in the sugar mixture before serving.
