Jilly's is an amazing cupcake place located just off interstate 170 in University City. They are the 2 time winners of Food Network's Cupcake Wars and were voted to have the best cupcakes in America by USA today. A bite into one of their expensive treats will show you why. All their cupcakes are freshly baked and you can chose from many exotic flavors. Some types are even filled with M&ms! The treats may be pricey but they are definitely worth it!
Also, next door is an ice cream shop owned by the same people. It is really good too. The cupcake store is only open until 6:00 but if you arrive late you can buy the left over cupcakes at the ice cream shop.
