Steak 'n Shake puts your birthday cake in a cup

This Saturday, Steak 'n Shake celebrates 80 years of mountainous burgers, thin-cut fries, and boat-side deliveries. To properly commemorate the occasion, the octogenarian chain is releasing a limited-edition Birthday Cake Milkshake, which will be available until August and marks the longest birthday party since your Mom forced you to go to stupid Kyle Creasman's sleepover in fifth grade. The shake comes packed with buttercream-frosted bits of yellow cake, ice cream, and a heap of sprinkles. It's going for $3.49, which is significantly cheaper than a Fudgie the Whale. Not that Mrs. Creasman would have been cool enough to get one of those.

Kristin Hunt is a food/drink staff writer for Thrillist and will order any milkshake with Reese's in it. Follow her to crushed candy mix-ins at @kristin_hunt.
