I know this because there are entire television shows devoted to them. While in San Francisco I saw a special cupcake place at the up-scale mall food court, so I decided I would try one. I had a hard time choosing my flavor. It was a debate among oreo, coffee toffee, s'mores, and raspberry lemonade.
It was a last minute change, as I had thought I had decided on raspberry lemonade, but then I saw that the raspberry lemonade had cream cheese frosting, and I usually prefer the sugar-sugar frosting. With hindsight I probably should have stuck with the first choice. The coffee toffee was much better on paper than in reality. It was also reported to me that oreo was amazing, so even my third choice probably would have been a better one.
Don't get me wrong -- I ate the entire cupcake (even though it had toppled over, despite the excellent carrying case design). And it was good. But I was kind of hoping it would be better than any cupcake I ever could have imagined.
As it turns out, this little cupcake stand, Cako, is going to be on Cupcake Wars (see above note on popular television shows devoted to cupcakes) today (or maybe tomorrow?). Sadly, I don't think they will win.
