BB, normalizing is fine, but one eats (or at least I eat) actual items of food, not grams. I don't buy a Cinnabon and discard a portion in order to bring the calorie/fat/sodium content down to a predetermined level; I eat the whole thing.
Three cake doughnuts, per the breakdown above, would yield 660 calories, still lower than one Cinnabon. Frankly, I find a Cinnabon too large, and too sweet with all the gook on it.
I like the cake doughnuts better in any case. In all likelihood I'd buy and eat two cake doughnuts (440 calories) and eat them, rather than buying a Cinnabon (730 calories).
