I particularly like that everything is very colorful, vibrant, insinuating happiness and good mood. The typography is pretty simple which is easy on the eyes and inviting. The images of all the foods look delicious and make me hungry. I might even experiment with a few of her recipes after seeing a cover like this one for example.

This one seems very simple with a lot of white in the background and a small photo of herself in the corner allowing us to focus in on this very strong image of a tasty looking dessert. Typefaces used are nice, again simple, and the image is very inviting with a little thing at the bottom stating the amount of recipes which is smart. The designer did a good job with this.
