  • 1 cup sugar
  • 1/2 cup brown sugar
  • 1 cup sour cream
  • 2 eggs
  • 1/2 cup unsalted butter softened
  • 2 cups bananas 3-4 ripened and mashed
  • 2 teaspoons vanilla extract
  • 1 3/4 cup all purpose flour
  • 1 teaspoon baking soda
  • 3/4 teaspoon salt


  • 1/2 cup butter unsalted
  • 1/4 cup caramel dip
  • 4 cups powdered sugar
  • 1 1/2 teaspoon vanilla extract
  • 3-5 tablespoons Cashew milk or whatever milk you want to use
  • 1/4 teaspoon salt


  • 1/4 - 1 cup cup chopped walnuts optional
  • 1/4 - 1 cup chopped mini semi-sweet chocolate chips optional


  • Heat oven to 375F. Spray with non-stick spray or cover pan with tin foil, (non-stick if you have it, otherwise spray it with non-stick spray) 15x10-inch jelly roll pan.


  • In a large bowl, using mixer, beat together sugars, sour cream, butter, and eggs until creamy.
  • Add in bananas and vanilla extract and blend.
  • Add flour, baking soda, salt, and continue to beat for 1 minute.
  • Spread batter evenly into pan.
  • Bake 20 to 25 minutes or until golden brown.
  • While bars are baking, you can make the frosting.


  • Heat butter in a large saucepan over medium heat until boiling and let butter turn a delicate brown color, then remove from heat immediately.
  • Add powdered sugar, vanilla extract, caramel dip and milk.
  • Whisk together all the ingredients until smooth. Frosting should be thicker than glaze but thinner than frosting.
  • Using a spatula, spread the brown butter frosting over the banana bars while they are still warm. I added the frosting about 15 minutes after I took the banana bars out of the oven. It makes it easier to spread onto the cake. YUM!!!


You could probably get by with making a 1/2 batch of the frosting recipe on these bars, if you want to still have the richness but not as many calories. I went all the way, my thighs will thank me later. :)
