Add eggs, one at a time, beating well after each addition. Sift flour with baking powder, baking soda and salt. Add to creamed mixture, alternately with sour cream. Pour half of batter in prepared pan. Combine the remaining 1/2 cup sugar with cinnamon and nuts. Sprinkle half on batter; dot with 1 tablespoon of the butter. Repeat layers, dotting with the remaining 1 tablespoon butter. Bake for 35 to 45 minutes. Cool in pan. Makes 12 servings.
