My mother used to make these for all my school parties at Sunset Acres Elementary.
1/2 lb. butter
4 heaping tablespoons powdered sugar
2 cups all purpose flour
1 teaspoon vanilla
1 cup chopped pecans
Combine all ingredients. Form into circles or crescents. If you do circles, you can make and indention with your thumb and you can fill the indention with red plum jam or chocolate kisses for something different. I like them with powdered sugar sprinkled on top. Bake 300 degrees until lightly browned. Sprinkle the powdered sugar on the cookies while they are hot.
