Slice apples using a mandolin slicer after removing seeds with apple corer.
Sprinkle cinnamon sugar on top of these slices.
Place the apple slices without overlap in the air fryer basket or you can also line them up in a skewer
Preheat the air fryer for 5 minutes at 120C | 240F.Place the apple slices in the airfryer basket.
Air fry the apple slices at 120C | 240F for 40-42 minutes.
Store these in a air tight container
Notes
If the airfryer option does not come down to 120C | 240 F, try using the bake option and see if that comes down, you can also try the dehydrate option, however that will take more time as that is at lower temperatures
