One number defines the Cookout Chocolate Chip milkshake: 43% of the Daily Value for iron, the highest figure in Cook Out's official nutrition guide, shared only with Chocolate Chip Mint. The 34.46 oz cup holds 783 calories and typically costs $3.99. The reviews are about its relatives, and they point in two directions.

Why does the Chocolate Chip shake have so much iron?
The guide lists 43% of the Daily Value, against a typical 2% for the menu, and the figure is more than three times the next-highest flavor at 14%. Chocolate Chip and Chocolate Chip Mint share it, so it travels with the chocolate chip mix-in, not the mint.

What do reviewers say about the chocolate chip shakes?
Opinions split by sibling. The fan scorer at cookoutmilkshakereviews.com gave both Chocolate Chip Mint and Chocolate Chip Cheesecake 15 of 17 and called the cheesecake the best cheesecake-flavored shake, hands down. The Daily Meal went the other way on a related flavor: it ranked a Chocolate Chip Cookie Dough shake 33rd of 41, describing vanilla ice cream, chocolate flakes and small dough bits that taste and feel like store-bought cookie dough candy.
TikTok users ask when Cook Out has its cookie dough shake, which suggests the dough flavors come and go.
What else does the label show?
Saturated fat reaches 20 grams, exactly the Daily Value, and fiber hits 4 grams, a rare number on a shake menu. Sodium stays at 472 mg, right at the typical flavor.

Same iron, same fiber, same saturated fat, and 51 fewer calories. Chocolate Chip Mint adds the mint for 834 calories in a 35 oz cup. If you want the chips without the extra sugar, this is the one.
What is the case for the Cookout Chocolate Chip milkshake?
It is a chip-studded shake with a label that stands out, the plain version of a flavor that has a well-reviewed mint sibling on the same shelf. Order it for the iron and fiber, and add mint if you want the version reviewers rate highest.
