Preheat your air fryer to 350°F.
Cut each biscuit into four equal pieces and roll them into balls.
Lightly spray the air fryer basket with non-stick spray or oil.
Place the dough balls in a single layer in the basket, ensuring they don’t touch.
Air fry for 5-6 minutes or until golden brown, shaking the basket halfway through.
While still warm, dip each donut hole in melted butter, then roll in a mixture of cinnamon and sugar.
Serve immediately and enjoy!
