Grab a mixing bowl and add the slices of peeled apple, butter, sugar, and cinnamon. Combine well.
Place the air fryer basket inside the Instant Pot and spray some nonstick spray inside the basket.
Add the apple slices to the basket.
Cover the Instant Pot with the Air Fryer Lid.
Air fry the prepped apples at 390 °F for 6 minutes.
Once the time has passed, remove the lid and serve :)

Notes
Try and slice the apples to be the same size so that they cook at the same pace.
Once you peel the apples, don't throw away those apple peels! You can actually fry them up on the stove and eat them as well. If you have a fruit dehydrator, you can dehydrate for a healthy snack.
If the apples are not as sweet as you want, you can always sprinkle some extra sugar on top, even after they're cooked.
Feel free to air fry for 1-2 more minutes if you don't like the texture.
