To help ease people into the holiday spirit, Jack in the Box is once again offering its perennially popular Pumpkin Pie and Egg Nog Shakes.

“Pumpkin pie and egg nog are two of the most popular and familiar treats of the holidays, and our Pumpkin Pie and Egg Nog Shakes have been seasonal favorites of our guests for several years,” says Bobby Brown, marketing manager for Jack in the Box. “The shakes are rich and thick and pack a lot of flavor. But they’re only available for a limited time, so don’t wait too long to begin celebrating the season.”

As with Jack’s other Real Ice Cream Shakes, the Pumpkin Pie and Egg Nog Shakes are available in regular (16 ounce) and large (24 ounce) sizes and are served with whipped topping and a Maraschino cherry on top.

Other shake flavors include Oreo Cookie, Vanilla, Strawberry, and Chocolate.

Pumpkin Pie and Egg Nog Shakes are not available in Bakersfield, California, and Portland, Bend, Eugene, and Medford, Oregon.
