We're planning on having 2 cakes at our wedding (a his/her cake because I really want a marzipan cake and he wants an ice cream cake) and then cupcakes. Our guest count will be around 170. Any recommendations on how many servings per cake/cupcakes we should get? I was thinking a marzipan cake that can serve around 40 (because it will be less popular), ice cream cake that can serve around 90, and then around 75 cupcakes. Would this be really off base?
