Indoor S'mores | Preheat the oven to 450. In a cast iron skillet, add the 1 cup chocolate chips. Snip 8 large marshmallows in half and top the chocolate chips with them. (You could also use a scoop of mini marshmallows alternatively.) Once the oven is up to temperature, add the skillet to the oven. Bake for 7-9 minutes, or until the marshmallows turn golden brown. Serve with gluten free graham crackers for scooping.
