Preheat air fryer to 350°F.
Cut a circle out of the center of each biscuit using a small 1" cutter.
Place 4-5 pieces of the dough in the air fryer.
Cook 3 minutes. Flip and cook an additional 2-3 minutes or until browned.
Remove from the air fryer and while warm, brush with butter. Combine sugar & cinnamon, toss donuts in sugar mixture.
