Unfortunately CookBook is intended just for storing your recipes on your app and creating your own personal CookBook, not as a physical cookbook creation tool.
We have added this request onto our ideas list however at the moment it is not something that we are looking to implement.
You do have the ability to print all of your recipes into a .PDF format which you could then make into your own cookbook.
You can also bulk export your recipes into HTML format inside a zip. Whilst these are not formatted for print, you might be able to print them into a single document on your PC, format them in a way you would like and get them printed into a physical CookBook. Please however be mindful of copyright, never claim a recipe as your own if it is not.

Can I make and print a physical cookbook from the recipes in my CookBook app?
