Place the graham crackers into the basket of the air fryer and place half of the marshmallow (sticky side down) onto each.
Cut your marshmallows in half ( kitchen shears work great) Then place half of the marshmallow onto each graham cracker (sticky side down)
Set the air fryer to 380 and cook for 3-5 minutes. Be sure to check often as each air fryer can cook differently . Marshmallow will begin to turn golden
Once golden , carefully remove from the air fryer basket and place a 1/4 - 1/2 of a piece of the chocolate bar on top of one marshmallow that is on a graham cracker and then place the other half onto it making a sandwich .
Allow the chocolate to melt for 30-60 seconds and ENJOY!
