Answer:

Cakes are like books, there are new ones you want to read and old ones you want to reread

Let us Dissect the quote:

"Cakes are like books...

For me, Ellen Rose meant that like books, a cake shouldn't be judged by its outward appearance. A cake may look simple on the outside, but when tasted, it gives a complex and harmonious flavor that is pleasing.

...there are new ones you want to read...

This simply means that there are a lot of cakes in the world we haven't eaten. And yet, more recipes for cakes are being created.

and all guys want to reread"

A well-made cake is something not to be easily fed-up with. We can eat the same cake every day because it is delicious for our palate(taste).
