Cinnamon Nut Cake

In a mixing bowl, combine the cake mix, eggs, water and oil. Beat on medium speed for 2 minutes. Combine walnuts, sugar and cinnamon. Sprinkle a third of the nut mixture into a greased 10-in. fluted tube pan. Top with half of the batter and another third of the nut mixture. Repeat layers. Bake at 350 degrees F for 35-40 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pan to a wire rack to cool completely. ');
