As Mom notes, it's a "Best Recipe"

A reminder to herself that it was her best chocolate chip cookie recipe.

As far as I'm concerned, it's the best cookie recipe ever.

NOTE: I use butter instead of oleo. 1 teaspoon vanilla.   2 t. baking soda + 2 t. salt.

What about directions?  Blend 1st 6 ingredients.  Add next 5.
