The groom's cake is a dessert made for the groom's taste buds. The bride often surprises the groom with a smaller cake at the ceremony made with flavors he loves.
The groom's cake is your time to have some fun at your wedding. Whether it's their favorite movie, sports team, or a restaurant they love, design the cake with a logo or something else fun.
The bride is supposed to take charge of the groom's cake effort. It can be done in total secrecy to avoid spoiling the secret reveal.
Weddings served groom's cakes later in the evening when everyone needed a sugar boost to keep them dancing into the late-night hours.
Ultimately, it's up to you to decide whether you serve the groom's cake. No one will miss it or gripe if you don't. Even your groom likely won't mind at all.
