Place four crackers in a basket and place one marshmallow half on each cracker. Place the sticky side of the halved marshmallow on a cracker so it can stick to it.
Air fry for 3 minutes, or until the marshmallow is golden brown on top.
Remove the crackers from the air fryer basket and place one chocolate square on each marshmallow. Allow it to melt for 20-30 seconds. Place another Graham cracker on each one and enjoy.
Notes
Mix-ins. Add banana slices, fresh strawberries, Nutella, or caramel for more flavor.
Use different chocolates. Instead of plain chocolate squares, use candy bars. I made s’mores with a Reese’s peanut butter cup once, and let me say, life-changing!
