I’ve been to weddings where there was no groom’s cake, but not that many-most of the time, it was a chocolate cake of some sort, either a sheet cake or with 2 layers-MrT5’s was chocolate with dark chocolate icing-German chocolate is popular, too...
i think that because a wedding cake is traditionally white or vanilla, the idea of the groom’s cake was to have some chocolate of some sort. Pretty sure xshub didn’t have one, bc we had a delicious choc chip cake. xsteen and xsfiance are looking at one or two layers of black/white mousse cake [DELISH, we have gotten their bday cakes in this flavor and it is to die for, very light and not overly sweet], a layer of bavarian cream and fruit with vanilla cake, and also a tiramisu cake layer.
