Klondike" is a brand name for a dessert generally consisting of a vanilla ice cream square coated with a thin layer of chocolate-flavored coating. The first recorded advertisement for the Klondike was on February 5, 1922 in the Youngstown Vindicator (Butko 2001: 8) They are generally wrapped with a silver-colored wrapper, upon which the mascot for the brand, a polar bear, appears. In the UK, the generic name for this type of dessert is choc ice. Unlike many similar frozen treats, the Klondike bar does not have a stick, a point often touted in advertising.
The Klondike bar was created by the Isaly Dairy Company of Youngstown, Ohio in the early 1920s. Rights to the name were eventually sold to Good Humor-Breyers, part of Unilever. It is known for its jingle slogan "What would you do-o-o for a Klondike Bar?"
