Cake for RD?

After looking on theknot for numerous hours this morning I came across a picture of a couple of cakes. I really want to make these for the rehearsal dinner. They look relatively simple, a couple sized small circle pans for the bride and a couple sized small square pans for the groom just stacked on top of each other then frosted. This would be a good way to save money too-this way we dont have to buy everyone individual deserts. I'm so excited to try this-I think I'll make a mock up closer to the date-I'll post and let you know how they turn out.
