Peel, core, and slice the apples. Toss them with the 2 tsp of vegetable oil until evenly coated.
Place the apples in a single layer in the air fryer basket.
Air fry the apples at 400 degrees F for about 14 minutes, or until the apples are starting to brown and tender. There's no need to stir or toss the apples during cooking time.
Place the cooked apples in a bowl and stir in the 1 tbsp maple syrup, 2 tsp sugar, and 1/2 tsp cinnamon until well combined.
