First, peel off the skin of the bananas and cut them in half. Place the cut bananas in the air fryer and optionally brush them with a layer of honey water to add a sweet flavor and caramelization. Bake the bananas in the air fryer at a temperature setting of about 180 degrees. For time, you need to bake for about 8 to 10 minutes to achieve the desired baked banana texture and caramelization.
