Cinnamon Swirl Bundt Cake is a tender, buttery vanilla cake with a ribbon of cinnamon-sugar running through the center. It’s cozy, moist, and perfect for brunch or dessert.
For the Cake:
1 cup (2 sticks) unsalted butter, softened
1½ cups granulated sugar
3 large eggs
1 tablespoon vanilla extract
2½ cups all-purpose flour
1½ teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
1 cup sour cream
For the Cinnamon Swirl:
½ cup light brown sugar
1½ teaspoons ground cinnamon
For the Glaze (optional):
1 cup powdered sugar
1–2 tablespoons milk
½ teaspoon vanilla extract
Preheat oven to 350°F. Grease and flour a Bundt pan.
Mix cinnamon swirl ingredients in a small bowl and set aside.
In a large bowl, cream butter and sugar until fluffy. Add eggs one at a time, then vanilla.
Whisk together flour, baking powder, baking soda, and salt. Add to wet mixture in 3 parts, alternating with sour cream.
Pour half the batter into the Bundt pan. Sprinkle cinnamon swirl evenly. Top with remaining batter.
Bake for 45–55 minutes, until a toothpick comes out clean. Cool 15 minutes, then invert onto a rack.
When fully cool, drizzle with glaze if desired.
Use Greek yogurt instead of sour cream if preferred.
Add nuts or chocolate chips to the swirl for extra flair.
Store covered at room temp for 3 days or freeze up to 2 months.
