Goldenberg Peanut Chews! The Goldenberg family originally developed the peanut chews in Philadelphia in 1917, and they were even used by the U.S. military as ration bars during World War I. The chews are made with peanuts, molasses, and a chocolate coating, and come in milk chocolate and original dark chocolate flavors. They're available in bite-sized snacks or as bars that are similar in size to a fun-size or Halloween-size candy bar. Goldenberg's Peanut Chews are a favorite in Philadelphia and the surrounding Mid-Atlantic states, and are considered by some to be the original energy bar.
