choc chip cookie recipe

From a friend on facebook, speaking about her mother's recipe:

"she always used the recipe on the back of the nestle semi sweet chip bag except she used stick margarine instead of butter and increased the flour to 3 cups (i think original recipe is 2 1/4). It makes them puffier and moist which i love instead of the flat cookies. They are what i grew up on and no other cookie comes close in my opinion."
