The Butterfinger candy bar was invented by the Curtiss Candy Company of Chicago in 1923. A Butterfinger bar consists of a flaky/crispy orange-colored peanut-buttery center covered with a chocolate coating. The Butterfinger of today may not, however, be quite the same as the original bar -- according to some reports, the original Butterfinger recipe was somehow lost when Nabisco acquired the Curtiss Candy Company. None of the old employees claimed to remember how to make the bars, so a new recipe had to be developed that customers would accept.
