Mix the raw crust, chocolate filling, and marshmallow topping in a single layer. Place it at the bottom of the fryer basket of an air fryer preheated at 400°F (200°C) and cook for 3-4 minutes until the marshmallows are golden brown and gooey. Carefully remove the s'mores from the air fryer basket using tongs or a spatula. Let them cool for a few minutes before enjoying your delicious air fryer s'mores!
