I have to admit that I was not a big fan of this cake. Not that it was bad, but I didn't think it was as good as other chocolate cakes I have made in the past. I liked the idea of using root beer in the batter and had high expectations for it (and so did my children), but in the end, it was a little disappointing. My three-year old who helped me make it said, "it doesn't take like root beer, but it's still good." But then again, I noticed later that she just ate the parts with the icing and left the middle of the cake on her plate--this from a little girl who usually devours all things chocolate. The recipe cautions against over-mixing the batter, and despite my best efforts not to overmix, the cake was dry and I had little lumpy flour bites in the finished cake.
However, I thought the icing was great (not too gooey or sweet) and I liked the idea of making it in a food processor. I normally have powdered sugar flying all over the place when making icing and this way, everything was nicely contained. And since the recipe makes a ton and I didn't end up using it all on the cake, the leftover icing was fabulous as a dip for fresh strawberries.
Overall, I don't think I would make the cake again--but I will definitely file away the icing for some other tasty concoction.
