Slice the Bananas:
Peel bananas and slice into uniform thin rounds (about ⅛ inch thick). Thin slices = even crispiness.

Preheat Air Fryer:
Preheat air fryer to 330°F (165°C). Spray basket lightly with cooking spray or use perforated parchment for easier cleanup.

Mix Cinnamon Sugar:
In a small bowl, combine the coconut sugar (or brown sugar) and cinnamon.

Coat Banana Slices:
Place banana slices in a bowl and gently toss with the cinnamon-sugar mixture until lightly coated.

Air Fry in Batches:
Arrange banana slices in a single layer in the air fryer basket/tray. Don’t let them overlap. Air fry for 10–14 minutes, flipping halfway through.

Check for Crispness:
Banana chips are ready when golden and crispy on the edges. Depending on thickness and air fryer model, you may need an extra 2–3 minutes.

Cool and Enjoy:
Transfer to a wire rack and let cool for 5–10 minutes. They’ll crisp up more as they cool. Enjoy as a snack or topping!
