Since cupcakes became popular at weddings a few years ago many couples have opted to cut and share a cupcake together.
Another option is to have your baker make a small cake that is either one tier or multiple, and cut into a cake but serve cupcakes.
It’s up to you and your groom if you feel comfortable cutting a cupcake or if you want to cut a small cake together. Ask your baker for some ideas, he may have come across a similar situation in the past.
