Free Milk with Whataburger CookiesCookies and milk are a great snack, no matter what your age. Whataburger agrees – and that’s why they’re offering free milk when you buy their cookies. Come in to any Whataburger on March 30 or 31 from 11 a.m. to 8 p.m. and order one of their chocolate chunk or sugar cookies, and you’ll get a free chocolate or regular milk to go along with it.
