The BEST fluffernutter sandwich

Fluffernutter sandwiches are a combination of marshmallow fluff and peanut butter on bread. Adding the crispy golden grilled bread into the mix just makes it that much more incredible.

My daughter raves about lunchtime when we have fluffernutters, but the day I decided to make a fried fluffernutter sandwich on the griddle I just about blew her mind. Her reaction was priceless and the plate was literally licked clean afterward.

Because peanut butter and marshmallow fluff cook and melt at such a low heat, were basically just throwing peanut butter and marshmallow fluff on toast.
