These are a Christmas favorite at our house. I made these while visiting my inlaws this Christmas. I think others call these cookies Russian Teacakes.
From: Mom aka Ruth Solter
1 cup butter
1 tsp. vanilla
1/2 cup powdered sugar
2 1/4 cups flour
3/4 cup finely chopped nuts (I use almonds)
Cream butter, sugar and vanilla together. Add remaining ingredients. Roll into 1" balls. Bake at 400 degrees for 10-12 minutes on an ungreased cookie sheet. The cookies should be set but not brown. While the cookies are still warm (not hot) roll in additional powdered sugar.
