Ah ha ha ha, so many great cake stories, between the post and the picture of your rainbow cheesecake in the comments!

Just in case you have not yet read snarp's translation of Kazuya Minekura's blog entry about the cake her assistant made her, here is the link (on DW), because in light of this post of yours, I think you would enjoy it. (It does include some uncomfortable details about the aftereffects of sensei's surgery.)
