4 cups all-purpose flour
1/2 cup white sugar
1/2 cup packed brown sugar
2 cups unsalted butter
1 teaspoon salt
2 teaspoons vanilla extract
3 eggs
1 cup all-purpose flour
3/4 cup white sugar
1/2 cup milk
Preheat the oven to 350 degrees F (175 degrees C). Grease cookie sheets.
In a large bowl, cream together the flour, brown sugar and white sugar until smooth. Beat in the butter, salt, vanilla and eggs until fully blended. Mix in the flour mixture, mix well. Fold in the salt/brown sugar mixture. Drop by rounded spoonfuls onto the prepared cookie sheets.
Bake for 15 to 18 minutes in the preheated oven, until lightly browned. Allow cookies to cool on the baking sheet for 5 minutes as they will be brittle. After cool cookies, remove from the baking sheet to cool completely.
