Find Out the Sex of Your Baby… in a Cake. This seems to be a new trend going around – ever heard of it? Here is how it goes – the new expectant couple hands a copy of the ultrasound in a sealed envelope with the sex of the baby marked on it from the ultrasound technician and asks the baker to create a cake that has the color of the future baby’s sex color on the inside of the cake. The couple then invites a bunch of people over for dessert and SURPRISE everyone finds out the sex of the new baby at the same time ! Let them Eat Cake ! Would you do this?
