Does mixing two flavors change the calories?

Cook Out lets you mix any two flavors at no extra cost, and a mixed shake lands roughly between the two flavors' numbers, since each flavor is only part of the cup. A Banana Pineapple (566) is itself a good example of how light a fruit mix stays.

Seasonal flavors

Fresh Watermelon (645 calories) runs in July and August. Eggnog and Peppermint arrive in December and are not in the year-round nutrition list, so treat them like the other rich flavors: expect 700 or more. The full flavor list with prices is on our Cookout milkshakes menu.
