Cook the S'mores: – Carefully place the graham cracker bases with the chocolate and marshmallow into the air fryer basket. If desired, lightly spray the basket with cooking spray to prevent sticking. – Air fry the s'mores at 375°F (190°C) for 3-4 minutes, or until the marshmallows are golden brown and the chocolate begins to melt. Keep an eye on them to prevent the marshmallows from burning.
– Assemble the S'mores:Once the marshmallows are golden and gooey, carefully remove the graham crackers from the air fryer. Immediately place the remaining graham cracker squares (with just peanut butter) on top of the melted marshmallows to create a sandwich.
