Use a peeler to remove the banana skin, then cut them into thin rounds about 1/8 inch thick. A sharp knife or mandoline slicer makes this easier to keep the cuts consistent.

Grab a small bowl and stir together the sugar and cinnamon until it's fully blended.
03 -
Brush both sides of the banana pieces lightly with the melted butter or coconut oil. Sprinkle your sugar-cinnamon mix over both sides evenly.
04 -
Lay the banana slices in a single layer inside the air fryer basket without overlapping. Work in shifts if necessary, depending on the size of your fryer.
05 -
Set your air fryer at 300°F (150°C) and cook for about 10-15 minutes. Flip the slices halfway through. Start checking once they hit 12 minutes—they should be golden, slightly crunchy, and will crisp up more after cooling.

Transfer the banana chips to a cooling rack and let them cool completely. Once they've cooled, munch on them right away or store in a sealed container for up to 3 days.
