Which sweet treat was introduced in 1932 and named after figures from literature?

First introduced by the Mars company in 1932, this popular candy bar took its name from the famous trio of heroes in Alexandre Dumas's classic novel. The name was more than just a literary nod; it was a literal description of the product. The original bar contained three individual pieces in one package, each with a different flavor of nougat: chocolate, vanilla, and strawberry. Marketed as a treat big enough to share with two friends, it was one of the largest and best-value candy bars on the market at the time.

This unique three-flavor format came to an end due to wartime rationing during World War II. The rising cost and scarcity of ingredients made producing the multi-part bar impractical. The company decided to streamline production, keeping only the most popular flavor of the three: chocolate. The bar was then reconfigured into the single, larger candy bar sold today, known for its distinctively light, whipped nougat that sets it apart from denser candy fillings. The name, however, remained as a legacy of its original three-part design.
