There is bacon in this cupcake and the top looks like an egg so I see NO good reason that this wouldn't be perfectly acceptable as a breakfast dish. Have at it.
I'm fairly certain that we've seen cupcakes posing as every food group, every meal throughout the day, every fantastical food we could imagine. I really appreciate that this has a gummy candy egg on it but real bacon. There is no reason to fake it with the bacon. That's the real lesson here.
