Great consistency, loved the cream cheese and sour cream together in this recipe. I happen to prefer a frosting that isn't overpoweringly sweet, but if you like, you could use a sweeter baking chocolate to begin with. This frosting was about as sweet as a good chocolate pudding--something not too rich, something you could eat right out of the mixing bowl. ;)
I was not a fan of this recipe. I love chocolate cream cheese frostings, but this one came out bitter and far too wet. I tried adding more powdered sugar and cutting the sour cream, which improved things a little bit, but not enough to keep the recipe.
