Pillow Cookies (Buttermilk Cookies)

These cookies are the perfect way to use up leftover buttermilk. They are so soft and sweet. I just made them yesterday and took them to some friends. Their comment, "Wow!! Best sugar cookies we have had in a long while!! Or ever actually to be honest!!" Then they begged for the recipe. :) I am happy to share! (I wish I could take credit for the recipe, but I got it from Quick Cooking magazine forever ago.)

½ cup butter or margarine, softened
1 cup sugar
1 egg
1 tsp. vanilla extract
2 ½ cups flour
½ tsp. baking soda
½ tsp. salt
½ cup buttermilk
        Cream butter and sugar until light and fluffy. Beat in egg and vanilla. Combine flour, baking soda and salt; add to the creamed mixture alternately with buttermilk and mix well. Drop by rounded teaspoonfuls (or use a cookie scoop) 2 inches apart onto greased baking sheets. Bake at 375º for 9-10 minutes or until edges are barely browning. Remove to wire racks to cool. Frost cookies (frosting recipe below). Sprinkle with chopped walnuts or sprinkles (I use sprinkles!), if desired. Makes about 3 dozen.

Frosting:
1 ½ Tbsp. butter or margarine, softened
1 ¾ c. powdered sugar
2 Tbsp. milk
½ tsp. vanilla extract 

        Combine all frosting ingredients in a bowl. Beat until smooth.
