Jeff and I stopped by Hey Cupcake today, since it is conveniently parked next to Hill Country Weavers. I had a red velvet cupcake with cream cheese icing, and Jeff had the carrot cake also with cream cheese icing. I tried to get mine filled with whipped cream, but they had run out, so no dice.
I want to say that this was the best cupcake that I ever ate, and that it's worth driving across town to get a $2 cup of heaven, but that wasn't my experience. I do heartily recommend that if you are nearby, when they are open, and they aren't sold out of cupcakes, and you like carrot cake, that you try the carrot cake cupcake. I couldn't get too into it, since I don't like raisins, but the cake around the raisins was superb.
The red velvet was pretty much on par with red velvet cake that you get anywhere else. There are red velvets that are horrid pieces of red dirt, and it wasn't like that. It's just like any other not sucky not great version I've ever tried. They have vanilla and chocolate cakes and vanilla and chocolate icings. I believe I heard the woman inside telling a woman on the outside that the vanilla icing is pink. (It matches the cupcake on the roof.)
So there you have it. It's surreal to get trailer-cakes, but not all that mind blowing. Who knows, you're mileage may vary.
