Preheat your cooker. Set your oven to 375°F (190°C) or your air fryer to 330–340°F (165–170°C). Line a baking sheet with parchment or give your air fryer basket a light spray.
Mix the topping. In a small bowl, stir together the sugar, cinnamon, and a pinch of salt.
Taste a tiny bit to make sure the balance is right for you.
Lightly coat the tortillas. Melt the light butter or measure the oil. Brush a thin layer over both sides of the tortillas. You want a whisper of fat—just enough to help crisp and hold the cinnamon sugar.
Cut into chips. Stack the tortillas and slice them into wedges (6–8 pieces per tortilla).
Even pieces cook more evenly.
Sprinkle the cinnamon sugar. Place wedges in a single layer on the tray or in the basket. Sprinkle about half the cinnamon sugar over the top. Flip the wedges and sprinkle the rest.
Aim for light, even coverage.
Bake or air fry. Oven: 8–12 minutes, rotating the pan halfway. They’re done when the edges are golden and the centers feel crisp to the touch.
Air fryer: 5–7 minutes, shaking or flipping at the halfway point. Watch closely the last minute to avoid over-browning.
Cool briefly. Let chips rest 2–3 minutes.
They’ll firm up as they cool, getting extra crunchy.
Portion and enjoy. Divide into two small servings for about 100 calories each, depending on your exact ingredients.
