Regarding mothermouse's doubling the dry mixture--would you please post exactly what you put in your cookies? Do you double the baking soda & salt?
Adding nuts to cookies makes them yummy too. Has anyone made the Nieman Marcus cookies??? They're to die for!
My DGD makes toll house cookies & she follows the recipe exactly (except for adding more flour), down to creaming the butter & sugars first & then adding the eggs one at a time, beating in between each. Her cookies are just sooooooo good. She uses all butter too.
My mom made toll house cookies using half margarine (stick) & half crisco. Hers were good too but the butter seems to make a huge difference.
