Mix sugar and cinnamon in a shallow bowl and set aside. Open can of biscuits, separate them and place them on a flat surface. Using a 1-inch round biscuit cutter, cut holes out of the center of each biscuit.
Lightly coat the Air Fryer basket with olive oil spray, then place donuts in a single layer into the basket. Make sure they are not touching each other. Bake at 360 Degrees F for 5 minutes or until lightly browned.
Remove donuts from the air fryer basket, dip each side in melted butter and roll in cinnamon sugar to coat.
In a small saucepan, bring apple cider to a boil and cook until reduced to half (about 7 to 10 minutes).
Slowly add in the powdered sugar while whisking the mixture to make sure there are no lumps, then add the light corn syrup. Whisk until all ingredients are evenly combined.
Let the mixture cool and thicken slightly before using.
