When I used the cookie scoop I cooked for 16-18 minutes.
When I pulled out one of the rolls of cookie dough, and slice it, I cooked them about 6-8 minutes.
I cook by timer and by smell. Something I learned from my MIL who was a fantastic cook.
Even though I buy an 11 oz. bag of Hershey's chocolate chips, I only use the reccommended 8 oz.s. Believe it or not, not over doing the chocolate, to me, makes a better cookie.
Mine are gone already, anybody got any? I'm hungry :-P
