A dense, buttery American classic using equal parts butter, sugar, eggs, and flour, enhanced with sour cream for moisture and tang. Perfect served warm or day-old with fresh fruit.
Preheat oven to 350°F (180°C) and grease a 10-inch tube pan.
Crack eggs into a mixing bowl and set aside.
In separate bowl, beat butter and sugar on medium speed for 3-4 minutes until light and fluffy.
Add sour cream and milk, mixing on low until emulsified.
Incorporate eggs one at a time, fully blending after each addition.
Add flour in two batches, alternating with vanilla extract, and mix until just combined.
Pour batter into prepared pan and smooth surface.
Bake for 65-70 minutes until firm and golden.
Cool in pan 10 minutes before unmolding.
Transfer to wire rack to cool completely.
Notes
Use room temperature butter for optimal creaming
