Unfold and cut puff pastry sheets in half lengthwise, and cut each half crosswise into 1-inch-wide strips. Twist each strip and place in an air fryer.
Air Fry for 4 to 5 minutes in a heated air fryer or until golden brown.
Meanwhile, combine sugar and cinnamon. Remove pastry strips from the air fryer, and dip in melted butter; roll in cinnamon-sugar mixture.
