Preheat your air fryer to 375°.

Break each sheet of graham crackers in half for a total of 8 graham squares. Divide your Hershey bar into four chunks (columns of three chocolate pieces per chunk).

Use a sharp knife or kitchen shears to carefully slice off one end of each marshmallow. This will make one side of the marshmallow sticky, keeping it from blowing off the graham cracker during frying. You can snack on the trimmings or reattach it to the marshmallow before frying.

Once preheated, place all 8 graham cracker squares into the air fryer.

Place one marshmallow, sticky side down on 4 of the graham cracker squares, the other 4 graham crackers will remain bare.

Reattach any marshmallow trimmings (sticky side down) to the top of the marshmallows sitting on the graham crackers.

Once the graham crackers and marshmallows are in place, air fry for 2 to 3 minutes at 375° until each marshmallow is golden brown and puffed and the graham crackers are nice and toasted.

Carefully remove the marshmallow grahams from the fryer.

Place a chocolate chunk on top of each marshmallow and top with the toasted, bare graham crackers. Enjoy!
