A great way to enjoy s'mores inside
Coat an 8 inch cast iron skillet with the melted butter.
Break apart the chocolate bars in the skillet. Put in a 400 degree oven for about 2 minutes so the chocolate gets a little melty.
Lay the marshmallows on top of the chocolate in a single layer. Put back in the 400 degree oven for 4-6 minutes or until the marshmallows are done the way you like them.
Serve with graham crackers on the side for dipping.
