This comes from Nestlé's offical site, Very Best Baking. I made half using 3/4 c. semi-sweet chocolate chips, 1/2 c. chopped toasted pecans, and got 27 using a 1 T./1.5" diameter cookie scoop. I baked the dough cold straight out of the refridgerator on 350 F, not 375 F, for about 9 minutes. They have decent flavor but I've made three or four other chocolate chip cookie recipes that I like better.
I give these 4 stars. The true original recipe for this has you add the baking soda to hot water, then add it to the dough.
