Notes
While you don't need to preheat the air fryer, it's still a good idea to let it warm up for a few minutes before placing the cinnamon rolls inside. This allows for more even cooking amongst your cinnamon rolls.
Line the air fryer basket with parchment paper to prevent the cinnamon rolls from sticking to the surface and make cleanup much faster.
Remember to consult the specific instructions on the package of your frozen cinnamon rolls, as they may provide additional tips for air frying.
