Vanilla Shake

What is it?

Thick, smooth, and poured cold, this shake is built from Shake Shack's house-churned vanilla frozen custard. It's a simple mix: custard, milk, and vanilla, with no add-ins or swirls. The result is denser than a typical fast food shake, since the custard base brings egg yolks and more body than soft serve or standard ice cream. Compared with the specialty shakes in the Shake Shack lineup, this one is the plain vanilla starting point. It's served across the chain and uses the same daily churned custard that shows up in the brand's other shakes and concretes.
