Why shouldn't his cake be just as involved? A Southern tradition, groom's cakes  can be just as elaborate as the wedding  cake. The main departure from a traditional wedding cake is that the design is typically more whimsical, and many reflect the groom's personality or hobbies. From Lord of the Rings to food themes, this roundup includes a variety of themes; we bet you'll find something for your guy that's full of personality.
