Preheat the air fryer to 350° for 4 minutes.

Open the can of biscuit dough and separate the biscuits.

Cut each biscuit in half. Roll each half into a ball.

Place dough balls the preheated air fryer and cook for 8 minutes, flipping halfway. Don’t crowd the air fryer basket, you may have to cook the holes in batches.

While the donut holes are cooking, prepare the topping mixture.

Place the butter in a bowl and microwave in 30 second increments until the butter is melted. Add cinnamon and sugar to a mixing bowl and whisk together.

When the donuts are finished, allow them to cool enough to handle. Submerge each donut hole in the melted butter and then immediately roll in the cinnamon sugar mixture.

Enjoy while warm!
