The Mountain Bar was first created in 1915 at the Brown & Haley factory in Tacoma, Washington. Originally called Mount Tacoma Bars, the name was changed in 1925 after Brown & Haley began distribution of the candy in Seattle. Shortly after World War II a cherry version of the Mountain Bar was introduced. This was followed by the peanut butter variety in 1974. Cappuccino and Mint flavored Mountain Bars were briefly available in 2010.
