This cake like cookie bar makes a great dessert, so moist and the browned butter frosting is delectable.

How to Make Sour Cream Banana Bars


  1. Preheat oven to 375-degrees. Grease and flour a jelly roll pan.
  2. Mix sugar, sour cream, butter and eggs in large mixer bowl on low speed, scraping sides occasionally for 1 minute.
  3. Beat in bananas and vanilla on low speed for 30 seconds.
  4. Add flour, salt and baking soda on medium speed, scraping bowl occasionally for 1 minute. Stir in nuts if using. (I like to add them to the top after frosting bars)
  5. Spread batter into pan. Bake until a light brown color, 20-25 minutes.
  6. Cool and frost with Browned Butter Frosting. Cut into bars, about 2x1 1/2 inches.
    Heat butter over medium hear until delicate brown. Remove pan from heat and mix in powdered sugar and milk until smooth and of spreading consistency.
  8. Butter is the only option for this frosting. Margarine will not give it the depth of flavor that browned butter imparts.
