Since Princess Celestia is the best and most harmonious Equestrian ruler, she is on the pulse of what the common pony wants. And that, of course, is cake! What diplomatic conference; what mingle with the ordinary street dweller; what moment of personal indulgence or melancholy, is not made better by cake? None, that's what, proving the truth in the saying our beloved and eternal monarch lives and dies on... hopefully not as literally as her more infamous colleague Marie-Antoinette, who may or may not have said something similarly cake related to a much more tough crowd.
Anyway, that should never be a problem here since, let us not forget, Princess Celestia: she's just like the rest of us. She understands you and her never-ending love will smother you even if you don't because she simply knows what's best for you. So shut up and stuff your face with delightful delectables until you won't even remember what you were so upset about before. Or as our magnificent Princess Celestia herself says: "More cake for a happier Equestria!"
