How many calories are in a Costco muffin?
Costco has begun to make muffins with streusel toppings, which substantially add to the calorie count; thus explaining the higher end of the calorie spectrum. While delicious, these muffins must be eaten in severe moderation to avoid major weight gain – it would only take 4 muffins to gain a pound. I know some people who eat that over a couple of days!
