Just after the Second World War, Danish candy producer Toms were contacted by the United States high command in Germany, which commissioned Toms to produce a candy bar for the American troops in Germany to avoid transporting such products across the Atlantic.
In return, the U.S. would supply Toms with the required amount of cocoa beans.
[1] Ten years later, in 1956, Toms launched the Holly Bar, similar to the Yankie bar, but with white nougat and roasted hazelnuts.
In its marketing, Toms relied on Americophilia to sell the Yankie Bar.
The brand was damaged by the Vietnam War, when "yankees go home" became a common anti-American chant, but its popularity rebounded after the war ended.
