1 c. butter, softened
2 c. sugar
3 eggs
2 tbsp. buttermilk
5 c. all-purpose flour
1 tsp. baking soda
1 tsp. vanilla extract
Additional sugar

Cream butter; gradually add 2 cups sugar, beating well. Add eggs, one at a time, beating well after each addition. Add buttermilk and beat well. Combine flour and soda; gradually stir into creamed mixture. Stir in vanilla. Chill dough several hours or overnight.

Roll dough to 1/4 inch thickness on a lightly floured surface; cut into rounds with a large biscuit cutter or a 3 1/2 cookie cutter. Place rounds 1 inch apart on a lightly greased cookie sheet; sprinkle with additional sugar. Bake at 400 degrees for 7-8 minutes or until edges are slightly browned.
