A year ago, Hostess Brands, then recently bought out of bankruptcy, was just launching what it called "the sweetest comeback ... ever." Turns out the boast may not have entirely been hyperbole. Four of the company's brands--Twinkies, Zingers, Ho Hos and Ding Dongs--have seen triple-digit growth in convenience stores since then, leading a rebound of the entire bakery snack category after four down to flat years of unit growth. The category grew 9.35% during the 52-week period ending Aug. 10, 2014, according to IRI, a Chicago-based market research firm (@iriworldwide).
