Mix cake mix, oil, eggs and sour cream and pour into a greased 9 x 13-inch glass baking pan. Pour one-half mixture into cake pan.
Mix brown sugar and cinnamon and spread evenly across batter. Pour other half batter on top and bake at 350 degrees F for 45 minutes to one hour. (Check after 45 minutes - middle should begin to pass the wooden pick test.)
