1 box Duncan Hines yellow cake mix
1/2 c. sugar
3/4 c. oil
4 eggs

Grease and flour bundt pan. Combine all ingredients in mixer. Pour 1/2 mixture in bundt pan. Mix 1 tablespoon cinnamon and 2 tablespoons sugar. Sprinkle half cinnamon mixture over cake. Pour rest of cake into pan. Add rest of cinnamon mixture. Bake at 350 degrees for 1 hour. (I baked mine about 50 minutes or will get too dark.)
