Is this the end of Twinkies? Hostess Cakes, the maker of Twinkies, Ding Dongs and Wonderbread, is declaring bankruptcy. The Twinkie has been a favorite snack since it was invented in the 30s. Its purported shelf life is legendary. Some believe that Twinkies never go bad. Hostess Cakes says this is not so and that Twinkies should only sit on the shelf for a couple of weeks. Hostess Cakes says the rising cost of flour and heavy pension obligations did it in. But some believe Hostess is declaring bankruptcy to wiggle out of pension fund obligations.
