Lightly coat the tortillas with oil or melted butter.
In a bowl, combine 4 parts sugar with 1 part cinnamon and a pinch of salt.
Generously sprinkle about ¾ of the cinnamon-sugar mixture over the tortillas until they are fully coated.
Place the coated tortillas in a single layer in the air fryer basket, working in batches if necessary.
Air fry at 375°F for 10 minutes, shaking the basket halfway through, or until they are golden and crispy.
Once cooked, toss the chips in the remaining cinnamon-sugar mixture and allow them to cool for 1–2 minutes before serving.
