I tried every custard shake at Shake Shack. Here's how they rank from worst to best.
Shake Shack introduced a new limited-edition flavor in August. Here's how it compares to the chain's other custard shakes.
Over the course of a year, I tasted and ranked every shake on Shake Shack's menu, from classics like chocolate and vanilla to limited-edition flavors like the Dubai Chocolate Pistachio. The Biscoff Cookie Butter Tiramisu shake, introduced in August, earned the second-to-last spot in my ranking. At $6 with 690 calories in a 16-ounce cup, the strawberry shake was the least favorite, with an overpowering strawberry scent and an uncomfortably sweet taste.
The Campfire S mores shake, a summer 2025 offering priced at $6.99 and containing 1,090 calories, was better but still unremarkable, featuring graham crackers, chocolate, and toasted marshmallow fudge chunks. The Chocolate Toasted Marshmallow S mores shake, released this year, was a slight improvement with a more marshmallow-forward flavor profile, but still didn't satisfy my taste preferences.
The Dubai Chocolate Pistachio shake, a limited-edition summer 2025 flavor costing $10.99 with 1,330 calories, was the least favorite among the holiday shakes, with its frozen chocolate and strange phyllo texture making it an unpalatable experience. The Christmas Cookie shake, Shake Shack's year-round holiday offering, was too sweet with a sugar-cookie custard and red and green sprinkles, ranking last among the holiday shakes.
