Depends on airport security. Make them look really really nasty and they will let you on with them. If they look too good, they might 'confiscate' them, LOL.
Just kidding, I think you are safe until someone tries using baked goods in an evil plot, but definitely check with the airport first. You can call the airline directly, or speak with airport security. I would speak with airport security as they do, technically, have the final word.
