This festive and enormous shake (it's hard to gauge the size but it's a very wide cup, haha) consisted of "Sugar cookie frozen custard topped with whipped cream and red and green sprinkles". The sugar cookie custard was super creamy and delicious, and the sprinkles added the perfect amount of holiday spirit haha. It reminded me more of a French Vanilla taste compared to a regular vanilla flavor. Of course I also loved their seasonal drink/shake cups with the cute penguins all around as well. I hope they bring these back again for the holidays this year!
