INGREDIENTS (Nutrition) 1 cup butter, softened 1 cup white sugar 1 cup packed brown sugar 2 egg 1 egg yolk 2 teaspoons vanilla extract 1 (18 ounce) jar peanut butter 2 cups all-purpose flour 1 teaspoon baking soda 1/2 teaspoon salt 1 cup chopped peanuts
DIRECTIONS In a large bowl, cream butter, white sugar, and brown sugar until smooth. Add the eggs, yolks, and vanilla; mix until fluffy. Stir in peanut butter. Sift together the flour, baking soda, and salt; stir into the peanut butter mixture. Finally, stir in the peanuts. Refrigerate the dough for at least 2 hours.
Preheat oven to 350 degrees F (175 degrees C). Lightly grease a cookie sheet.
Roll dough into walnut sized balls. Place on the prepared cookie sheet and flatten slightly with a fork. Bake for 12 to 15 minutes in the preheated oven. Cookies should look dry on top. Allow to cool for a few minutes on the cookie sheet before removing to cool completely on a rack. These cookies taste great when slightly undercooked.
