Step 1: Slice the Bananas
Peel the bananas and slice them into uniform thin rounds—about 1/8 inch thick is ideal. Thin slices ensure even cooking and crispness.

Step 2: Preheat and Prep the Air Fryer
Preheat your air fryer to 330°F (165°C). Lightly spray the basket with cooking spray or line it with perforated parchment for easy cleanup.

Step 3: Mix the Cinnamon and Sugar
In a small bowl, combine the coconut or brown sugar with the cinnamon. Set aside.

Step 4: Coat the Banana Slices
Place the banana slices in a mixing bowl and gently toss with the cinnamon-sugar mixture until lightly coated.

Step 5: Air Fry in Batches
Lay the banana slices in a single layer in your air fryer basket or tray, making sure they don’t overlap. Air fry for 10–14 minutes, flipping halfway through.

Step 6: Check for Crispness
The chips are ready when golden brown and crisp at the edges. Some may need an extra 2–3 minutes depending on thickness and air fryer model.

Step 7: Cool and Crisp
Let the chips cool on a wire rack for 5–10 minutes. They’ll crisp up even more as they cool.
