This is another one. I've read it and enjoyed it immensely! Kate secretly bought it for me and then saw me reading my own copy and said "where did you get that?"
It's about a secret starter with a mind of its own.
I read "A wizard's guide to defensive baking" and liked it a lot.
I also read a Naruto fanfiction where the main character discovers the joy of baking. The main characters is a rather burned out Ninja who has lots of friends.
