  3. 2 Beat together in a mixer the butter and sugars. Beat in the eggs one at a time. Mix in the vanilla and mashed bananas.
  4. 3 Mix in half of the flour mixture, then the sour cream, then the other half of the flour mixture.
  5. 4 Spread batter evenly in a greased 10x15 baking pan. Bake at 350°F (175°C) for 20 minutes, or until nicely browned and the surface bounces back when you press it with your finger. Cool completely before frosting.
