Ingredients:
- 1 box yellow cake mix
- 4 eggs
- 1 c. sour cream
- 3/4 c. vegetable oil
- 1 c. brown sugar
- 2 tsp. cinnamon
Frosting
- 2 c. powdered sugar
- 6 Tbsp. milk
- 1 tsp. vanilla
Preheat the oven to 325 degrees and combine cake mix, eggs, sour cream and oil by hand until well mixed and set aside. Combine brown sugar and cinnamon separately in another bowl until everything is mixed well; set this mixture aside as well. Pour half the cake batter in an ungreased 13×9 pan; spread out well; add half of brown sugar mix on top covering the entire surface and then swirl by using a knife around your cake batter surface before pouring remaining batter and topping off with remaining brown sugar mix before spreading with remaining batter before pouring rest of batter from spreader pan and spreading out before covering everything before pouring the final batch and swirled by using remaining brown sugar mix topped off by one last swirled knife swirl pattern! Bake 45-50 minutes; when cake has come out of oven pour frosting onto hot cake surface while it still warms through or serve warm!
