To melt the chocolate chips, place them in a bowl and microwave in 30 second increments until melty. I like to take a spoon and drizzle this around the rim.
Fill each glass with both chocolate and vanilla ice creams. Add a pinch of smoked sea salt into the glass. Pour the root beer over top just before serving. Sprinkle on the graham crackers and add a charred marshmallow on to finish. Devour!
As a note, you can char the marshmallows on a gas range, under the broiler (watch them the entire time!) or even just get them melty in the microwave if you don't have a bonfire of sorts.
