A childhood staple and an adult favorite, the peanut butter sandwich has a special place in all of our hearts and stomachs. The sandwich rose to popularity during WWII, due to rationing at home and its inclusion in the meals of soldiers. The sticky sandwich long outlasted the war and is consumed in 89 percent of U.S. households. Here are eight of the most popular sandwiches that peanut butter is used in.

Fluffernutters - A gooey, sticky combination of peanut butter and marshmallow that has been a source of controversy this year, but is a firm favorite with anyone who likes marshmallow.

Marshmallow Fluff is a wonderful concoction of sugar, corn syrup, egg whites and vanilla that is whipped into a creamy and spreadable goo.

It's most famous use is the Fluffernutter Sandwich, which combines peanut butter and Fluff between two slices of bread, and this is what is getting the sweet stuff into trouble. While parents have packed Fluffernutter sandwiches as special treats in kids' lunchboxes for many years, some parents recently noticed that they are being included as a school lunch option by the schools themselves - 1 out of every 14 schools, to be exact.

Williams-Sonoma sells a marshmallow and peanut butter chocolate-covered candy under the same name. The products were available over the 2005 Holiday season and do not seem to be in stores at the moment.
