I was prepared not to believe the negative hype about Magnolia's. After all, people love to bash popular places. And I also love Buttercup, which a lot of people don't. Turns out the (Chowhound) crowd was right this time. I tried out a cupcake at the upper west side Magnolia's location and it was really authentically BAD. Not just mediocre, but bad. The frosting had this terrible chalky flavor to it that I think comes from using way too much confectioners' sugar. Well, here's adding one more voice to warn people away.
Buttercup, Sugar Sweet Sunshine, and Sweet Revenge all are far superior.
