Place a piece of parchment paper in the air fryer and lightly spray it with cooking spray. Place the cinnamon rolls on the paper.
Cook at 350 degrees F for 6 minutes. Flip the rolls over. Remove the parchment paper and cook for 6 more minutes.
To make the frosting, mix the melted butter, vanilla, and powdered sugar together in a bowl until smooth. Add a tiny bit of milk to smooth it out, if necessary.
Top with frosting and enjoy.
All air fryers have different wattage and may cook at different rates. You may need to adjust the time or temp for the best results.
