Groom's cakes are not traditional in my circle. FI loves chocolate and PB combo and we did not get that for our wedding cake, so I was thinking of adding a small one on as a groom's cake as a surprise. But I'm not really familiar with the whole concept. Is it served at the reception also? Who eats it, - it just another optional flavor for the guests? Is it small enough just for groom/groomsman? I know it's often done in a humorous style - is it displayed next to the regular wedding cake? Can anyone enlighten me?? Thanks all!
