I have to give credit where credit is due! The applause for this delicious creation goes to my Sister-In-Law, Kathy. She served this when I was at home a few weeks ago and I ate almost every bite she sent home to the hubs! I've never baked with sour cream but this came out wonderful!!! I baked a few in wide mouth pint mason jars - the presentation was amazing! We love this and I hope you do too!
1 (18 1/4 ounce) box yellow cake mix
3⁄4 cup oil
1 cup sour cream
1 cup brown sugar
1 tablespoon cinnamon
2 cups white powdered sugar
4 tablespoons whole milk
Preheat oven to 325°F Grease a 9 x 13 inch baking pan.
Mix together cake mix, eggs, oil and sour cream. Pour into prepared baking pan.
In a separate bowl combine brown sugar and cinnamon. Sprinkle evenly over cake batter then swirl into batter with a knife. The more you swirl, the more combined it will be so don't over-swirl otherwise the cinnamon/sugar will not be swirly.
Bake for 40 minutes.
