I have become a fan of Bakerella recently and finally tried making some cake balls myself. I made two different kinds...
(1) Homemade Chocolate Cake with Cream Cheese Icing and Chocolate Bark Coating
(2) Hummingbird Cake with Cream Cheese Icing and White Bark Coating
The Hummingbird Cake ones were a little bit of an experiment. The Hummingbird Cake is so moist by itself that after crumbling it and adding some icing it didn't hold it's shape after rolled into balls very well. But even though they dind't look perfect, everyone seemed to really love how they tasted!!
