Yup, I have no idea what they are called but this is one of those sweet cakes that have a lot of egg and butter. I think it's called... castilla? I dunno... Don't worry though, the first part of the Yuu comic will come up soon, but it'll likely take a long time to see his origins for some irritating reason. Sorry >_>'

EDIT: Forgot to give credit where credit is due! I actually cheated (muhahahahaha!!!) and used someone else's recipe! So it's not my recipe! Here is where I got the recipe: http://www.aayisrecipes.com/2006/05.....mple-egg-cake/
So~ if you want to make it... go there! And don't forget to show the lady some love!!! The good non-creepy won't-get-you-arrested kinda love. You know what I mean... I hope -_-'
