When your work department consists of a bunch of librarians, it is almost a given that you will be able to wow with a book-shaped cake. When you grow up in my family, it is almost a given that you will find a book-shaped cake pan in your parents' basement (or a Donald Duck shaped pan for that matter).
For our big WPS Library Department end of the year celebration this year, I made this book cake. It was a marble cake with some kind of non-descript frosting. I tried to be clever and wish good luck to our department members who are moving on. I still have that often referenced on Cake Wrecks spacing issue, but I'm working on it.
All in all, it was a thunderous success.
