Whoever was in charge of the custard orders on this day was feeling very generous- haha! This is Shake Shack's Caramel Walnut Cake custard that I tried recently. The custard may appear to just be a caramel custard, but there was lots of little walnut chunks throughout as well. I mainly got caramel and walnut flavors, and nothing that specifically made it like a cake (aka cake pieces or something like that). I normally always want chocolate in my desserts, but this one had a ton of caramel flavor that I really liked, so I would recommend it for anyone that likes caramel!
