Cinnamon Coffee Cake Recipe

In a large bowl, cream butter and 2 cups sugar until light fluffy. Add eggs, one at a time, beating well after each addition. Beat in vanilla. Combine flour, baking soda and salt; add alternately with sour cream, beating just enough after each addition to keep batter smooth. Spoon a third of batter into a greased 10-in. tube pan. Combine cinnamon, nuts and remaining sugar; sprinkle a third over batter in pan. Repeat layers two more times. Bake at 350 ° for 60-65 minutes or until a toothpick inserted near the center comes out clean. Cool for 15 minutes before removing from pan to a wire rack to cool completely.
