Who are they copying?

I saw a beautiful, simple, elegant cake on a blog today and saved the photo. Five minutes later, on a different blog, from a different wedding, I saw the same cake. It didn't seem like they were from the same bakery, so what are these cakes emulating? A Martha? Anyone know?

In any case, steal this cake design! It is chic, modern and PERFECT for your wedding.

Sorry, I don't have the credits!
