How many calories are in a Costco apple crumb muffin?

There are anywhere from 610 calories to just over 1,000 depending on the flavor of the muffin. Specifically, poppy seed muffins weigh in at 610 calories and 32 grams of fat (6g saturated) while the chocolate ones are 690 calories with 37 grams of fat (?).

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!

Of course, making your own is a healthy alternative which allows you to control what goes into the muffins. If you can't or don't have time to make your own, cut the muffin in half, remove the streusel topping and only eat half the muffin. Drink a little milk afterwards - this does two things. It gives your body some protein which helps prevent a spike in your blood sugar and it washes the taste of sugar out of your mouth reducing the likelihood of your craving and eating the other half.
