Step 1

Turn on the air fryer to 360 degrees F and preheat for 3 minutes.

Step 3

Open the tube of biscuits and separate. Use a 1-inch circle cutter to cut out the centers. Lightly spray each side of the biscuits with coconut spray.

Step 5

Place 3 to 4 donuts in the air fryer basket, making sure the edges don't touch each other. Cook for 4 to 5 minutes, flipping once, until both sides are well-browned. Turn out on a baking tray lined with a wire rack. Repeat with the remaining biscuits.

Step 7

Melt the butter and brush over the donuts. Top generously with cinnamon sugar (see below) and/or sprinkles.
