Method
- Preheat oven to 350°F (175°C) and grease a 9x13 inch baking pan thoroughly.
- In a large bowl, whisk together flour, granulated sugar, baking powder, and salt.
- Add melted butter, milk, eggs, vanilla extract, and sour cream, mixing until just combined.
- In a small bowl, combine brown sugar, cinnamon, and melted butter for the swirl mixture.
- Pour half the batter into prepared pan, sprinkle with cinnamon mixture, then top with remaining batter.
- Use a knife to create swirl patterns by cutting through the batter in figure-eight motions.
- Bake for 35-40 minutes until a toothpick inserted in center comes out with few moist crumbs.
- Cool for 15 minutes, then prepare glaze by whisking powdered sugar, milk, and vanilla until smooth.
- Drizzle glaze generously over warm cake, allowing it to cascade down the sides.
Notes
Store covered at room temperature for up to 5 days. The sour cream keeps the cake moist and tender. Can be frozen for up to 3 months when wrapped tightly.
