Start by coring out the apple. If you want to use the top again, make sure you cut it off, then core it.
In a small bowl mix your filling together, raisins and walnuts, feel free to mix that out with oats they taste amazing. Then mix in your butter.
Scoop the filling into the apple, and sprinkle some of the spices on top.
Set your apple into an air fryer safe pan and cook for 20 minutes at 350 degrees F.
Remove from air fryer, plate, serve and enjoy!
