If you or your betrothed has a sweet tooth, serving wedding cake -- and only wedding cake -- may be a challenge. Enter the wedding dessert bar. To plan a wedding dessert bar guests will love, try sticking to a single theme (multiple types of pie, a set color palette, etc.)...or just go wild! And rather than send your guests home with a tummyache, set out bags or boxes so they can take extra dessert home with them.
