1/2 lb. butter
2 c. flour
1 c. sour cream
3/4 c. sugar
1 tsp. cinnamon
3/4 c. nuts

Cut butter into flour with a pastry blender until crumbly. Stir in sour cream with a fork, blending well. Divide dough into 4 parts. Chill 3 hours or longer. Roll each part on a slightly floured surface in an 8-inch round. Sprinkle with sugar, cinnamon and nuts. Cut into 12 pie-shaped wedges. Roll up, starting at wide side. Put each on an ungreased cookie sheet. Bake at 350 degrees for 20 minutes. Drizzle with a powdered sugar glaze.
