Rainbow Air Fryer Donuts

1. Remove the biscuits from the can, separate them, and place them on parchment paper.
2. Use a 1-inch round biscuit cutter (or similarly-sized bottle cap) to cut holes out of the center of each biscuit.
3. Lightly coat an air fryer basket with olive or coconut oil spray.
4. Transfer donuts to the air fryer basket. Lay them in a single layer, working in batches as necessary.
5. Air Fry at 350 degrees Fahrenheit for 5-6 minutes, until golden brown.
6. To make the Glazed Topping: In a small bowl whisk together the powdered sugar, milk and vanilla.
7. Dip the donut into the glaze and top with sprinkles or make a fun rainbow using pre-made decorator icing.
