This sandwich is totally addictive! It's amazing how well peanut butter and marshmallow creme go together so well on bread. I guess it would be the combining taste of something sweet and salty, smooth and sticky. Hope you enjoy this as much as I do. I usually can't stop with just one of these sandwiches. I sometimes have to have two. P.S. I don't use a lot of the marshmallow creme because it is so sweet. Usually a thin layer works well with any amount of peanut butter, but it's to your preference.
