Batter..
1 box butter recipe golden cake mix either Pillsbury or Duncan Hines brand ( Reserve 1/4 of it)
4 eggs
1 8 ounce container sour cream
1/4 cup water
1/4 cup white sugar
1/3 cup oil
Filling...
1/4 cup reserved dry cake mix
2 Tablespoons brown sugar
2 teaspoons cinnamon
1/2 cup diced pecans
Heat oven to 375 degrees and grease a bundt cake pan. Combine all the batter ingredients and mix until well blended. Then pour 2/3 of batter into greased pan. Combine all the filling ingredients and sprinkle onto the batter in pan.
Pour on remaining cake batter and smooth out. I always lift the pan and
gently tap it on the counter top to even it out. Place on center rack of oven and bake for one hour or till toothpick comes out clean. Cool on rack and keep in air tight container.
