If you’re at a birthday party, is there ANY kind of cake you wouldn’t eat? What about “wiener cake”? Oscar Mayer is celebrating the 90th anniversary of the Wienermobile this weekend, with WIENER CAKES. It’s basically a bunch of hot dogs arranged around a two-tier cake, along with ketchup- and mustard-colored confetti. You can buy a Wiener Cake at select Milk Bar locations in New York, Los Angeles, and Chicago starting on Friday, while supplies last.
