Twinkies may be smaller than people recall NEW YORK Twinkies are back, but they may be a bit smaller than you remember. The new boxes hitting shelves list the cakes as having 270 calories and a weight of 77 grams for two cakes, or 135 calories and 38.5 grams for one. Right before it went out of business, the snack cakes' former owner had told the Associated Press Twinkies were 150 calories per cake. Photos of past boxes online also indicate the weight to have been 42.5 grams per cake. A spokeswoman for Hostess says in an email Monday that the size change was made in "mid-2012" by the predecessor company. That would mean it happened quietly in the months leading up to its bankruptcy, as the company was trying to keep its head above water financially.
