Dice the apple into small pieces, then in a small bowl mix together the diced apples and cinnamon.
Make a small hole in the middle of your biscuit, which you will be filling. Be careful not to cut through to the other side.
Stuff as much filling as you can.
Grease your pan with either non-stick cooking spray or olive oil spray. Then place your stuffed biscuits on top of the tray, being careful not to crowd them, as they will expand during cooking.
Set your air fryer to 330 degrees for 5 minutes, then flip and cook for another 3 minutes.
Meanwhile, make your icing, mix together the confectionery and milk. Keep on adding milk and stirring until you get a thin coating.
Drizzle the icing over the fritters.
Plate, serve and enjoy!
