A rich, buttery Bundt cake swirled with cinnamon sugar for a warm, bakery-style flavor. Perfect for brunch, holidays, or cozy weekends.
Cake Batter:
2 ½ cups all-purpose flour
2 tsp baking powder
½ tsp baking soda
½ tsp salt
1 cup unsalted butter, softened
1 ¼ cups granulated sugar
3 large eggs
1 cup sour cream or Greek yogurt
½ cup whole milk
2 tsp vanilla extract
Cinnamon Swirl:
½ cup brown sugar
2 tsp cinnamon
1 tbsp all-purpose flour
2 tbsp melted butter
Optional Glaze:
1 cup powdered sugar
2–3 tbsp milk
½ tsp vanilla extract
Preheat oven to 350°F (175°C). Grease and flour a Bundt pan.
Mix the swirl ingredients in a small bowl and set aside.
Whisk flour, baking powder, baking soda, and salt in a bowl.
Cream butter and sugar until fluffy. Add eggs one at a time. Mix in vanilla.
Blend in sour cream, then alternate adding dry ingredients and milk.
Pour half the batter into the pan. Add cinnamon swirl. Swirl gently. Top with remaining batter.
Bake 50–60 minutes, until a toothpick comes out clean.
Cool in pan 15 minutes, then invert and cool fully.
Drizzle with glaze if desired.
Don’t overmix — it can toughen the crumb.
Let cool completely before slicing for clean cuts.
Store at room temp, wrapped, for up to 4 days.
