1 (21 ounce) package Cinnamon Streusel Coffee Cake mix (includes 1 package streusel)
3 eggs
1/3 cup oil
1 cup water
1/2 cup Kemps Sour Cream

Streusel Mix
1 package streusel mix from cake mix

How to

Preheat oven to 350F.
Coat a 13 x 9-inch baking pan or 12-cup coffee cake ring pan with cooking spray.
In a large bowl, combine the cake mix, water, oil, eggs, and sour cream on low until moistened.
Beat 2 minutes at medium speed. Set aside.
In a small mixing bowl, combine all the ingredients for the streusel topping. Using a fork, blend the mixture until it is crumbly.
To assemble, pour 1/2 of the cake batter into the baking pan. Sprinkle with 1/2 of the streusel mix. Spread with remaining batter. Top with remaining streusel mix.
Bake for 35 to 40 minutes or until a toothpick inserted into the cake comes out clean.
Cool cake completely before glazing.
