"101 Perfect Chocolate Chip Cookies" (2000) by Gwen Steege - youropinion?
 

Assuming you've used it, of course.

I saw it in a second-hand bookstore and thought of getting it, but I
have too many cookbooks already.

Here's part of one review:

"......the third one I tried was on page 43, Nutty Chocolate Chip
Cookies. At first glance, I thought they left out some ingredients,
but I followed the recipe exactly, and to my surprise, the result was
a very light, and very delicious NOT sweet cookie - no sugar 'high'
after eating these (nice for a change)."
