Turn on the oven broiler (which is generally 500-550°). Let it warm up while you assemble the s'mores.
On a baking sheet place half of the graham cracker squares, top with a chunk of chocolate and two marshmallows each.
Place in the oven on the middle rack, for 3 MINUTES. Stay close so that your marshmallows don't burn, you will be able to smell them when they start to brown.
Put the top graham cracker on each s'more and smoosh it down.Enjoy your melted chocolate and soft toasty marshmallow s'mores!
Notes
Make as many as you can fit on the baking sheet!!!
