I ate a whole bunch of cupcakes, but most of them were minis so I don't feel so bad. My favorite one that I had was a full sized Lava Fudge (A chocolate cake with gooey chocolate ganache center topped with our vanilla buttercream frosting and a chocolate ganache swirl) one from Hill Country Cupcake. They were also super nice and kept the raspberry one that I bought for lordaerith in the cooler for me until I was leaving. Left before the cupcake eating contests.
I'd go again next year. I just hope they have it in a bigger place.
