Preheat the air fryer to 350 F for 3 minutes.
Combine the butter, cinnamon, and sugar in a small bowl. Cut the peaches in half and remove the pits.
Brush the cut side of the peaches with oil and place skin side down in the air fryer. Air fry for 5 mins.
Add a spoonful of the butter mixture into the peaches.
Air fry for an additional 5-6 mins, until the peaches are caramelized on top.
Serve immediately and top with ice cream, granola, honey, and cinnamon. Enjoy!
