Since its late and I have to wake up in the morning to study for a quiz and go to the store to prepare for C5's first week-ishly/monthly Fiesta, I'll go ahead and give you the recipe. It may involve boxed cake mix, but it tastes far from it. Mandy is now famous.
Lutheran Coffee Cake
1 stick of butter
1 box yellow cake mix
1 box vanilla pudding
8 oz sour cream
Mix together butter and cake mix and pudding. Add in eggs and sour cream. Pour half the batter into a greased cake pan. Liberally sprinkle cinnamon sugar over the layer. Pour the remaining batter on top. Bake at 325 for 40-50 minutes.
Sidenote: I'm especially thankful for having a professor who I can borrow from. Thanks to Dr. Davis for the bunt pan!
