Here’s a closer look at the new shakes:
Chocolate Birthday Cake Shake: Milk Bar B’Day crumbs and Milk Bar B’Day frosting hand-spun with chocolate cake frozen custard, topped with whipped cream and rainbow sprinkles.
Cornflake Chocolate Drizzle Shake: Milk Bar Cornflake Crunch hand-spun with malted vanilla frozen custard, topped with Milk Bar chocolate fudge drizzle and mini marshmallows.
Both limited-edition shakes will be available at Shake Shack locations nationwide starting Friday, September 3, but Shake Shack and Milk Bar fans alike can get exclusive early access to the shakes via the Shack App starting Tuesday, August 31, 2021.
As part of the partnership, Shake Shack and Milk Bar will be donating treats to The Birthday Party Project, a non-profit that brings joy to children experiencing homelessness through the magic of birthday parties.
