In a medium-size bowl, mix the granulated sugar and apple pie spice. Set aside.

Remove the biscuits from the can and peel to separate each into two layers. Press each layer of biscuit into a 4-inch circle. (You will have 16 circles.)

In a small bowl, combine the apple pie filling with cinnamon. Mix to combine.

Spoon about 1 tablespoon of the apple pie filling and cinnamon mixture into the center of each biscuit circle.

Use your fingers to fold the sides together, pinching to seal. Roll into balls.

Spray the basket of an air fryer with nonstick cooking spray.

Working in batches, place the balls into an air fryer basket about 2 inches apart. Spray the tops with cooking spray.

Air fry at 350°F for 8-9 minutes, or until golden brown.

Carefully remove the balls from the air fryer, dipping each in melted butter.

Roll each dipped apple pie bomb into the apple pie spice and sugar mixture. Repeat with the remaining batches.

Serve immediately or at room temperature.
