Cake artist Lily Vanilli makes cakes that look like human hearts. Musician Tim Wheeler featured one in one of his music videos, which you can watch at the link. In the video, he devours the cake, and it's surprisingly realistic on the inside, too. At least, what I would imagine a person eating a human heart would look like. Because I've never actually seen that happen. So that's more of a speculative assumption on my part.
