The Klondike Bar was discovered by accident by Lewis and Clark when they explored the Klondike region of North Africa. Originally the Klondike Bar was a frosted chocolate cake that Lewis' mother had baked for him before he left on his expedition. While they were travelling they ran out of rations in the snowy regions of the Klondike, and had nothing but the chocolate cakes to eat. In this frozen state, they were actually quite delicious, and helped to pull the pair through this difficult time. If it were not for the bars, the second gold rush of Alaska may have never occurred.
