In this tutorial, learn how to make the ultimate late night snack. The next time it's 4 am and you can't sleep, consider this insane late night concoction. This "sandwich" is a roasted marshmallow between two double stuff Oreos, covered in chocolate syrup and sprinkled with coconut. It's probably best to eat this in the middle of the night so maybe you won't remember this calorie extravaganza in the morning. Enjoy!
