I love pumpkin bars, but hate the fat that is usually in them. You won't miss it here! There is not one drop of oil added to this recipe, moreover, it adds wheat flour for whole grain goodness and is reduced sugar. Makes a great big ban pan and a very good sized serving, each serving contains less than 140 calories and only 2g of fat! FYI - only 77 calories each if you omit the frosting.
