So until I got engaged I had never heard of a grooms cake. It was in one of my wedding planning books that my grandmother had given me. I asked her what a grooms cake was and she said it is the cake that all the single women attending the wedding will take a slice from to take home and put under their pillow and that is supposed to give them dreams about their future spouse. I thought that was a funny and weird little "legends has it" kind of tradition. But now on wedding wire it seems like grooms cakes are smaller cakes that are meant for only the groom? I'm not sure. I'm not sure if maybe my grandma got things mixed up or maybe I'm mixing two different things up? What do most people think a grooms cake is for?
