Remove the core from the top 1 inch and bottom 1 inch of each apple.
Use a mandoline or sharp knife to cut into ⅛-inch thick slices.
In a small saucepan, combine the maple syrup, brown sugar, cinnamon, salt, and cayenne pepper. Cook for 5 minutes over medium heat, stirring frequently.
Brush the apple slices with the mixture.
Preheat your air fryer to 375 ° F.
Arrange the apple slices in a single layer, working in batches.
Cook for 8 minutes and then flip. Cook for another 4 minutes.
Reduce the heat to 325° F. Cook for another 8 to 10 minutes until the desired crispness is achieved.
Allow to cool. The apple chips will continue to crisp up as they cool.
