Preheat oven to 350 degrees F. Grease a bundt pan with nonstick cooking spray.

In a small bowl, combine the flour, baking soda, and salt.

In a large mixing bowl, cream the butter and sugar together until light and fluffy. Continue beating and add the eggs, one at a time, scraping bowl after each.

Stir in the vanilla and sour cream.

Slowly stir in the flour mixture, just until combined.

Pour batter into prepared pan and bake for 45-60 minutes or until a toothpick inserted into the center of the cake comes out clean.
