Ingredients:
1 Cup butter
1 Cup creamy peanut butter
1 Cup white sugar
1 Cup packed brown sugar
1 Teaspoon vanilla extract
3 Eggs
4 Cups all-purpose flour
2 Teaspoons baking soda
1/4 Teaspoon salt
Filling:
1/2 Cup creamy peanut butter
3 Cups confectioners' sugar
1 Teaspoon vanilla extract
5-6 Tablespoons milk
In a mixing bowl, cream butter, peanut butter and sugars. Add vanilla. Add eggs one at a time beating well after each addition. Mix flour, baking soda and salt in a separate bowl. Add to mixture in mixing bowl. Shape into 1 inch balls and place 2 inches apart on ungreased baking sheets. Flatten with tins of a fork. Bake at 375 degrees for 5-6 minutes (important so that you don't over bake!!). Remove from oven and leave on cookie sheet for 2-3 minutes to allow the cookies to continue absorbing the heat from the cookie sheet. They should be slightly brown on the bottom. Cool on wire racks. In a mixing bowl combine and mix the filling ingredients until smooth. Spread on half of the cookies and top each with another cookie. Yield 5 dozen.
