Butterfinger is a candy bar manufactured by US-based Ferrara Candy Company, a subsidiary of Ferrero. It was formerly manufactured internationally by Nestlé.[1] It consists of a layered crisp peanut butter core covered in a chocolate-like coating; the coating is not eligible to be described as chocolate, as it contains no cocoa butter.[2][3] Butterfinger was invented by Otto Schnering of the Curtiss Candy Company in 1923. A popularity contest chose the name. In its early years, the Butterfinger was promoted by Shirley Temple in the 1934 film Baby Take a Bow. It was advertised by characters from The Simpsons (most notably Bart Simpson) from 1988 to 2001.
