How much cake?

How much cake do I need to order?  This is the most common question I receive from brides.  And understandably so.  While today's bride wants to make sure all their guests get to enjoy their dessert, they don't want tiers and tiers of cake left over to take home either.  For those who are only having a bride's cake, the answer is simple: 1 serving per guest.  But, what about the couple who chooses to have a bride's cake and a groom's cake?  The tradition is to have one serving of bride's cake per guest and 1/2 serving of groom's cake per guest.  So, if you have 150 people at your wedding, you will want a bride's cake that serves 150 people and a groom's cake that serves 75.  The reason is simple.  Almost everyone will want a piece of bride's cake because, well, it's been a centerfold of the reception for the last few hours.  Guests have ooed and awed over the stacked treat, taken pictures, and made comments about wanting to dive in and sneak a bite.  Since a groom's cake is usually a chocolate based cake, it won't be as popular of a choice.  Some people will skip the chocolate because they don't care for the flavor, or they are so full from the bride's cake that they cannot fit another bite into their mouth.  While you will probably have a little bit of bride's cake left over, expect to run out of groom's close to the end of the evening.
