Butterfinger Butterfinger is a candy bar created in 1923 in Chicago, Illinois by Otto Schnering, which currently is manufactured by Nestlé. The bar consists of a crispy core of creamy peanut butter blended with sugar candy in chocolatey coating. Butterfinger has become known for humorous marketing and a roster of memorably funny spokespersons, including Bart Simpson, Top Cat, Seth Green, Erik Estrada, Rob Lowe, and Jaime Pressly, its most recent and first female spokesperson. Other memorable ad campaigns include counting down the end of the world or BARmageddon, with evidence such as the first-ever, QR-shaped crop circle in Kansas, a Butterfinger comedy-horror movie called “Butterfinger the 13th,” the first interactive digital graphic novel by a candy brand starring the Butterfinger Defense League, and several attention-grabbing April Fool’s Day pranks, including the renaming of the candy bar to “The Finger.”
