Ingredients: 1 1/4 cup all-purpose flour, 1/2 cup white sugar, 1/2 cup packed brown sugar, 1/4 teaspoon baking soda, 1 egg, 1 teaspoon vanilla extract, 1/2 cup butter, 3/4 cup chopped walnuts. 

How to make: Preheat the oven to 375 degrees ( 190 degrees C ). Grease cookie sheets. In a medium bowl, stir together the flour, white sugar, brown sugar and baking soda. Add the egg, vanilla and butter mix until dough forms. Stir in the chopped walnuts. Roll dough into 1-inch balls and place 2 inches apart onto the prepared cookie sheets. Bake for 8 to 10 minutes in the preheated oven, until the edges are golden brown. Allow cookies to cool on baking sheet for 5 minutes before removing to a wire rack to cool completely.
