1/4 cup water

Preheat oven to 375. Grease and flour desired pan (usually a regular bundt/10 inch tube pan).
In a large bowl, mix cake mix, sour cream, oil, white sugar, water and eggs. Beat at high speed for 2 minutes.
Pour 2/3 of the batter into prepared pan.
Combine pecans, brown sugar and cinnamon. Sprinkle mixture over batter in pan. Spread remaining batter evenly over filling mixture.
Bake at 375 for 45-55 minutes. (cake should spring back when touched lightly)
