Inside the Hostess Factory: How Twinkies are Made

Created in 1930, Twinkies are America’s guiltiest pleasure. Using an elaborate and incredibly efficient system of Auto Bake robots, Hostess produces roughly 500,000,000 Twinkies a year, or roughly 1,000 a minute.

Interesting fact: The earliest Twinkies were stuffed with banana cream until a banana shortage in World War II forced the company to switch to vanilla. (Source: Popular Mechanics)
