Groom's Cake

Another tradition that was more prevalent in early American ceremonies is the grooms cake. Usually a dark cake to contrast the wedding cake, it was a second cake that was present at the reception as well. The reason for this second cake is not commonly known. There are claims that the grooms cake was to be served to the bridesmaids by the groom with a glass of wine. Another claim states that the grooms cake is to be saved and shared with friends after the honeymoon. This tradition is not widely recognized in most ceremonies, but there are still some observances of this in the southern half of the United States.
