famous amos cookie recipe

look what i found!
i was looking for good cookie recipes and found this: http://ampin.wordpress.com/2006/10/15/famous-amos-secret-recipes-cookie/

A lady was eating at famous amos, and found it so excellent that she asked if they would give her the recipe.
The waitress said that she could buy the recipe, at two fifty.
About a month later, that lady received her credit card statement and the recipe was two hunfred and fifty dollars!!!
She complained to Famous Amos but they refused to do anything about it.
So now she's put the recipe up on her blog, hoping to get some form of revenge.

So, here it is:

Ingredients
2 cups butter
4 cups flour
2 tsp. baking soda
2 cups granulated sugar
