Ingredients
Method
- Preheat oven to 350°F (175°C) and grease a 10-12 cup bundt pan thoroughly.
- Whisk together 3 cups flour, baking powder, baking soda, and salt in a bowl.
- Beat butter with 1 3/4 cups granulated sugar for 3 minutes until fluffy, then beat in eggs one at a time and vanilla.
- Alternate adding the flour mixture and sour cream to the butter mix, stirring until just combined.
- Stir together brown sugar, cinnamon, remaining 1/4 cup granulated sugar, and 2 tbsp flour. Layer half the batter, half the cinnamon mix, rest of batter, and rest of cinnamon mix in the pan.
- Bake 50-55 minutes until a toothpick has moist crumbs. Cool 15 minutes, then invert onto a plate and serve.
Notes
Let the cake cool in the pan for exactly 15 minutes before turning it out; any longer and the sugar crust may stick. The crackly top is at its best the day it’s baked, but the cake stays moist at room temperature for days when stored tightly covered.
