  • In a small bowl, stir together mashed bananas, sour cream, and vanilla; set aside.
  • In the bowl of an electric mixer fitted with the paddle attachment, beat 1 1/2 sticks butter and 1 2/3 cups sugar on medium-high speed until light and fluffy, 3-4 minute Scrape down the sides as needed.
  • Add the eggs, one at a time, beating well after each addition.
