1 pkg. Duncan Hines butter recipe golden cake mix
1 c. (8 oz.) sour cream
1/3 c. oil
1/4 c. sugar
1/4 c. water
4 eggs

FILLING MIX:

2 tbsp. reserved cake mix
2 tsp. cinnamon
2 tbsp. brown sugar
1 c. finely chopped nuts

Preheat oven to 375 degrees. Combine filling ingredients and set aside. In a large bowl, blend cake mix, sour cream, oil, sugar, water and eggs. Beat at high speed for 2 minutes. Pour 2/3 of the batter in a greased and floured tube or bundt pan. Sprinkle filling ingredients over batter in pan. Spread remaining batter evenly over filling mixture. Bake at 375 degrees for 45 to 55 minutes, until cake springs back when touched lightly. Cool right side up for about 25 minutes, then remove from pan. For a glaze, blend 1 cup confectioners' sugar and 2 tablespoons milk. Drizzle over cake.
