1 bx yellow cake mix
3/4 c veg oil
1 c sour cream
1 c brown sugar
1 tbsp cinnamon
2 c powdered sugar
4 tbsp milk
1 tbsp vanilla
Preheat oven to 325º
Butter or spray a 13x9" baking pan, set aside.
In a large bowl combine cake mix, oil, eggs and sour cream. Stir by hand, about 50 strokes will do or until large lumps are gone. Pour half of your batter into prepared pan.
Combine brown sugar and cinnamon and sprinkle evenly over batter. Spoon the other half of batter over cinnamon sugar. Using a knife, swirl so it looks like a honey bun, just in crazy eight patterns or the letter "s". You know how to do it.
Bake for about 40 minutes
To make your frosting just whisk powdered sugar, milk and vanilla until smooth. Pour over hot cake. Let set up for about an hour.
