Instructions

1. Preheat oven to 350°F. Grease and flour a 13x9-inch pan or use baking spray with flour and set aside.
2. In a large bowl, beat cake mix, oil, eggs, and sour cream on medium speed for 2 minutes. Scrape bowl and mix for an additional 1-2 minutes or until thoroughly combined.
3. Spread half of the batter into prepared pan.
4. In a separate medium bowl, stir together the brown sugar, pecans, and cinnamon. Sprinkle the brown sugar mixture over batter in pan.
5. Drop remaining cake batter by dollops over the brown sugar mixture. Carefully spread the batter to evenly cover the brown sugar mixture completely.
6. Bake 40-45 minutes or until golden brown and cake springs back when touched lightly in center.
7. When the cake has finished baking, remove from the oven and allow to cool completely.
8. In a small bowl, stir powdered sugar, milk and vanilla together until thin enough to drizzle. Drizzle the glaze over top of the cake.
9. Store covered.
