Spray the basket of the Air Fryer or Ninja Foodi with the oil.
Place the cinnamon rolls evenly into the basket.
Set aside the icing.
Air Fry or Air Crisp the cinnamon rolls for 8 minutes at 360 degrees. (SEE NOTE)
Check these around 7 minutes to be sure they are cooking well due to the heat difference in air fryers.
Once done, remove and top with icing.
Based on feedback, if you see the tops are browning well at the 4-5 minute mark, go ahead and carefully flip them over so they cook on the other side. I have not had to do this with the Ninja Foodi Air Fryer; however, based on feedback it appears it's necessary for many other air fryers.
