Gender cake question

I'm using "gender cake" because "sex cake" doesn't really convey the proper idea...now onwards:

What sort of places do gender cakes? Do you have to go to a foo foo bakery, or will a supermarket (like Publix) do it?

DH's bday is right around the anatomy scan time, so I thought it would be cool to have a gender cake as his bday cake (bday cake on the outside, but with pink or blue frosting on the inside.)
