Butter cream with fondant details. I made this, in just a few hours, for my own birthday, as a practice cake. The cakes did not have time to settle and the butter cream cracked, but it was just for a family get together, so not a big deal. It is all chocolate, my favorite! I saw so many of these, I had to try one = ) I wanted to add 2 love birds but ran out of time and added butterflies instead. I am hoping them to be a bridal shower cake favorite.
