Peanut Butter Sandwich Cookies

Preheat oven to 375 degrees F (190 degrees C).

In a large mixing bowl cream the shortening 1 cup creamy peanut butter and white and brown sugars. Add vanilla and then eggs one at a time. Beat well after each addition. In a small bowl combine flour baking soda and salt. Add slowly to creamy mixture.

Shape into 1 inch balls and place on an ungreased cookie sheet 2 inches apart. Flatten balls with a fork.

Bake for 7-8 minutes depending on size (I tend to keep a close eye on them and remove them as soon as they start to get golden. This helps to make them chewy.) Cool on wire racks.

To Make the filling: Combine 1/2 cup creamy peanut butter confectioners' sugar vanilla extract and milk in a small bowl adding enough milk to make for a creamy frosting like texture. Spread frosting on one cookie and top off to make \sandwich\.
