If you don’t have a deep fryer or don’t want to use it, donuts can be fried in a saucepan on the stovetop with some oil or in the air fryer. Keep your oil between 350° F and 360° F if you are frying on the stovetop. If you are air-frying your donuts, you can air fry them at 350° F, flipping them halfway through, and cooking them until they are golden brown. Note that the air frying method won’t work for more liquid batters.
