For the fourth consecutive holiday season, the Peppermint Chocolate Chip Milkshake is returning to Chick-fil-A menus as a limited-time flavor. Hand-spun  and topped with light whipped cream and a maraschino cherry, the milkshake will be available as supplies last until early January in 14 oz. or 20 oz. cups.

As an added bonus during the holiday season, Chick-fil-A the “Eat Mor Chikin” Cow calendar is back with 12 of history’s most famous “moonarchs.”

A digital “gift” card is included with the purchase of a cow calendar that comes pre-loaded with a free Chick-fil-A menu item each month of the year. Customers will be able to register their digital cards online, activating monthly rewards redeemable in-restaurant and in the drive-thru.

The 2013 Cow Calendars are now available for purchase at all freestanding or mall Chick-fil-A locations for $6 (plus tax) through early January, or until supplies last. Calendars can also be ordered online at www.chick-fil-a.com.

So with all this talk of Chick-Fil-A milkshakes which is your favorite?
