If you're looking for a gourmet cupcake in Tempe, this is the place. It's a little expensive, but it's that kind of store, so no big surprise. I agree with the other reviewers that there is a lot of frosting (almost the same height as the cupcake itself), but it's heavenly if you like frosting and get a flavor you like.
I had a strawberry cupcake (the one with the strawberry butter cream frosting, not the strawberry cream cheese frosting) and the mojito flavored ones. I really loved the strawberry one. It was very light, frosting and all. The mojito one was so-so. Hard chunks of lime rind and wayyyyyyyy too much mint flavor in the frosting and cake. It should be renamed mint.
A friend had the cookie dough one and said both the cake and frosting tasted like actual cookie dough. She said it was amazing.
All their cupcakes are beautifully decorated, which is nice, especially if you're getting one as a present for someone else. Some times the people in the store (employees, owners or other customers) can be very pushy, which is a major turn off. But I haven't had that experience every time I've been there.
The Tempe location is supposed to be getting some frozen yogurt added to their menu options soon. That may help those who need to mellow out so much frosting.
I would recommend this place to anyone who wants a little sweet fix and are in the Mill district.
