1 box yellow cake mix (butter recipe best)
4 eggs
4 tbsp. granulated sugar
3/4 c. oil
1 c. buttermilk
1 c. brown sugar
1 1/2-2 c. confectioners' sugar
4-5 tsp. cinnamon
1/2-1 c. raisins or nuts (optional)

Mix brown sugar and cinnamon and set aside. Mix cake mix with eggs, buttermilk, oil and granulated sugar. Fold in raisins or nuts with spoon. Spray with Pam; 13 x 9 inch pan. Pour in 1/2 of the batter. Sprinkle 1/2 of the sugar-cinnamon mixture over batter. Add remaining batter and sprinkle remaining sugar-cinnamon mixture over batter. Swirl mixture until batter and sugar and cinnamon is well blended. Bake at 350 degrees for approximately 45 minutes - test doneness with toothpick.

ICING:

Add enough milk to the confectioners' sugar to make it spreading consistency. Spread over cake in pan while warm.
