Peanut Butter Sandwich Cookies

Peanut butter cookies are awesome, and with a peanut butter filling just adds to it's awesomeness!!

1/2 c. butter, softened

1/2 c. butter flavored shortening(I use the crisco sticks)

1 c. creamy peanut butter

1 c. sugar

1 c. packed brown sugar

3 eggs

1 tsp. vanilla

3 c. flour

2 tsp. baking soda

1/4 tsp. salt

Filling:

1/2 c. creamy peanut butter

3 c. powdered sugar

1 tsp. vanilla

5-6 Tblsp. milk

Cream butter, shortening, peanut butter, both sugars until light and fluffy. Add eggs one at a time, add the vanilla. Combine the flour, baking soda, and salt and gradually add to the creamed mixture. Shape into even balls 2 inches apart on an ungreased baking sheet, flatten with a fork to make cross hatches. Bake at 375 degrees for 7-8 minutes or until golden. Cool on wire racks. Combine all filling ingredients and beat until smooth, adding more milk if neccessary. Spread on bottom of cookie and top with another one to make a sandwich.
