- Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
- Whisk together milk and sour cream in a separate bowl.
- Add dry ingredients to butter mixture in three additions, alternating with milk mixture, beginning and ending with dry ingredients. Mix on low speed just until combined.
- Pour half of batter into prepared bundt pan and spread evenly.
- Sprinkle half of cinnamon sugar mixture over batter in pan.
- Pour remaining batter over cinnamon layer and spread evenly.
- Sprinkle remaining cinnamon sugar mixture over top of batter.
- Gently swirl cinnamon through batter using a butter knife in figure-eight motions.
