Preheat the oven to 450 degrees.
Heat a 10-inch skillet on low heat on your stovetop. When the skillet is warm, add the butter and, after melted, use a pastry brush to coat the sides and bottom.
Remove from the fire, stir in the chocolate chips, and top with a thin coating of marshmallows.
Bake for 5 to 6 minutes on the middle rack of your preheated oven, or until the marshmallow tops are golden brown.
Serve warm with graham crackers after carefully transferring the skillet to a trivet (the pan will be hot!).
