In a small bowl, combine granulated sugar and ground cinnamon. Whisk them together until well-mixed and set aside.

Melt butter, then brush both sides of the tortillas generously with it.

Sprinkle the prepared cinnamon sugar mixture evenly over the buttered tortillas.

Roll each tortilla tightly and cut them into 1-inch pieces.

Preheat the air fryer to 350°F. Place rolled tortillas in the basket and cook for 5-7 minutes, shaking halfway through.

Once golden, let them cool for a minute or two before serving warm.
