Preheat your air fryer to 380°F (193°C).
In a mixing bowl, combine sliced apples, melted butter, maple syrup, cinnamon, and vanilla extract.
Toss the apples until they’re well coated with the mixture.
Spread the apples in the air fryer basket in a single layer.
Air fry for 10-12 minutes, shaking halfway through, until the apples are soft and golden.
Serve warm, optionally topped with granola, ice cream, or whipped cream.
