Ingredients Nutrition


  1. Heat oven to 375°F Grease and flour 15x10-inch jelly roll pan. For the bars, in a large bowl, beat together sugar, sour cream, butter, and eggs until creamy. Blend in bananas and vanilla extract. Add flour, baking soda, salt, and blend for 1 minute. Stir in walnuts.
  2. Spread batter evenly into pan. Bake 20 to 25 minutes or until golden brown.
  3. Meanwhile, for frosting, heat butter in a large saucepan over medium heat until boiling. Let the butter turn a delicate brown and remove from heat immediately.
  4. Add powdered sugar, vanilla extract and milk. Whisk together until smooth (it should be thicker than a glaze but thinner than frosting). Using a spatula, spread the brown butter frosting over the warm bars (the frosting will be easier to spread while the bars are still warm).

I saw this posted on FB this morning and I made the recipe this looked THAT good! Yes, it tastes as good as it looks, too. I'm not the biggest fan of banana tastes but this banana bread brownie is truly amazing. It's moist, sweet, flavorful and memorable. Both my kids and my husband had 3 helpings tonight for dessert! I will definitely be making these again for dessert and for parties. Yum!!

Thick, rich, moist, and the sour cream made it so yummy! I've never made a frosting like that, and I'm definitely a fan. More cake/bread like than a traditional brownie texture. No walnuts, so I used pecans, excellent results that way as well. Thanks for sharing, it was a good one! Made a lot, so the remainder will be cut, wrapped in plastic wrap, bagged and frozen for a later treat.

I also saw this on FB and made them last night. Way too sweet for my family. I'm not really sure why they are called brownies because they are really just very moist banana bread squares. Although they were yummy (with out the frosting) I will not make them again because my banana bread recipe is better.
