ELI5: What is a Groom's cake and why do people have them?
gpt
It can be very difficult to make a wedding cake large enough to feed all the guests at a wedding, so in the American South they started to have the tradition of having a second cake that was called the groom's cake. Where the wedding cake is normally white and highly decorated (thus bridal) the groom's cake is normally chocolate or red velvet and far less decorated.
