                Preheat your air fryer to 300°F (150°C) for 5 minutes.
              
              
              
                02 - 
                Peel the bananas and slice them into ⅛-inch-thick rounds.
              
              
              
                03 - 
                In a small bowl, mix the sugar and ground cinnamon until well combined.
              
              
              
                04 - 
                Gently toss the banana slices with the melted coconut oil or butter, ensuring each piece is lightly coated.
              
              
              
                05 - 
                Sprinkle the cinnamon-sugar mixture over the coated banana slices, tossing gently to ensure even coverage.
              
              
              
                06 - 
                Arrange the banana slices in a single layer in the air fryer basket, ensuring they do not overlap. You may need to work in batches depending on the size of your air fryer.
              
              
              
                07 - 
                Air fry the banana slices for 15 minutes, flipping them halfway through the cooking time. Monitor closely to prevent burning.
              
              
              
                08 - 
                Once golden brown and crisp, remove the banana chips from the air fryer and transfer them to a wire rack to cool completely. They will continue to crisp up as they cool.
