In a small bowl, combine the sugar and apple pie spice. Set aside.
Open the can of the biscuits and pull each biscuit apart in the middle, dividing them equally, so you now have 16 circles.
Roll each circle into a thin round shape, about 3-4 inches in size.**
In a medium bowl, combine the apple pie filling pieces with the cinnamon. Stir together to combine well, so the apple bites are coated.
Place a spoonful of the filling into the center of each circle of dough, leaving about ¼ inch around the edges.
Grab the edges and pull up, then pinch them together, making small round balls.
Use parchment paper with holes, or lightly brush the basket of your air fryer with olive oil. Depending on the size of your basket, place bombs in the basket and leave about ½ inch in between each piece. Don’t overcrowd or overlap in the basket. Work in batches if necessary.
Cook them in the air fryer at 350 degrees for about 6-8 minutes, until the biscuits are golden brown.
Once they are all cooked, dip each piece into the melted butter, then dip into the combined sugar and spice mixture. Repeat until all of the pieces are coated.
