Yep. Hoax.
NOBODY buys a custom cake and doesn't check it for spelling mistakes, etc.
And the whole wedding cake thing makes no sense either.
It's a small, cheap round cake.
No self-respecting gay couple would have THAT as their cake, even if it just said "love wins". ONLY at the top?
The rest of the cake was bare?
It must be quite a small wedding if that's the cake.
If I was to guess, I'd say that the decorator and the "minister" were both in on it.
As far as hoaxes go, this one is pretty lame.
I hope Whole Foods sues this guy blind.
