Peel the large banana and add it to a medium mixing bowl. Thoroughly smash the banana using a fork.
Add the pancake mix to the bowl and stir until the ingredients start to clump together in large clumps.
Using rubber gloves, if desired, spray nonstick spray on hands (or gloves) and start to knead the ingredients together. Don’t overmix. Knead and mix with your hands until the dough all comes together. It will be a little sticky, this is perfectly fine.
Roll the dough into 1 tablespoon sized balls (about 1 inch), making sure to keep your hands or gloves well greased.
Spray your air fryer basket with nonstick cooking spray and place as many of the dough balls as you can in the air fryer basket, spacing them about 1 inch apart as they will expand. I usually fit about 6 at a time in my 2-quart air fryer.
Air fry for 7 minutes at 350 degrees fahrenheit. Carefully remove from the basket and repeat until all the dough has been used.
Coat the donut holes in a topping or eat immediately.
