Mrs. Field's Chocolate Chip Cookies

Or so they say.  This is the cookie recipe I grew up on.  I haven't used it in years.  I think it might be time for a bake off soon.

1 1/3 sticks of butter
2/3 cups brown sugar
1 1/2 cups white sugar
3 eggs
2/3 Tb vanilla

Cream those ingredients well together.  Then add...

2 cups flour
1/2 tsp salt
1/2 tsp baking soda
chocolate chips

350 for 8-10 minutes
