Banana Bread Brownie Recipe

These banana bread bars are such a delicious dessert and easy to make! You only need a simple set of ingredients to make these bars and they will just melt in your mouth. If you love banana bread, you will go BANANAS over these brownies!

This recipe is a bit different than traditional banana bars since it has a more dense texture like chocolate brownies. We love creating different flavors of brownies including vanilla brownies, lemon brownies, pumpkin brownies and butterscotch brownies.

Ingredients You Will Need:

  • Butter– Use unsalted butter to control the amount of salt in the recipe.
  • Sugar- granulated sugar.
  • Vanilla– Pure vanilla extract is best.
  • Sour Cream- this will make the banana brownies extra moist.
  • Eggs– Use these at room temperature.
  • Flour– Use all-purpose flour for the best results.
  • Bananas– These will need to be mashed for the recipe and you will need 3-4 bananas.
  • Powdered Sugar– This is used for the homemade cream cheese frosting.

How To Ripen Bananas Quickly and Freezing Bananas:

To ripen your bananas fast, you will need a paper bag. Place the bananas you’re using into a paper bag to quicken the process. If you need an even faster way to ripen your bananas, add 1 or 2 apples into the paper bag. Freezing Bananas: Bananas can be placed in the freezer.

    I found this to be a wonderful use of brown bananas, some other recipes didn’t need 3-4 bananas but that’s what I had. I didn’t include nuts but will add them next time. The bars are hearty, frozen well & had wonderful banana flavor. Ready to investigate other recipes that you have. Thanks for the quick recipe.

    This is called a brownie, but it’s not chocolate! It has the density of a brownie. Not heavy like banana bread, nor light and airy like cake. It is fabulous! The texture and taste are spot on! Use with or without the cream cheese frosting depending on your sweet tooth! I personally don’t care to add anything to the batter such as nuts (well maybe raisins?) but you I can if you’d like. Just be sure to use the toothpick test to assure its fully baked.

  3. I added baking soda as this recipe did not include any leavening agents. I also used GF flour. I omitted the frosting and used whipped topping instead. This was a hit with everyone and was requested a week later as our super bowl party contribution! The 2nd batch is cooling. The cc frosting ready. I’ll let you know if round 2vturned out as well as the first one!

    1. The second batch was not as ooey gooey good. Not sure why. Maybe I under baked the first batch? Trying this recipe as single serve muffins today and added some Vietnamese cinnamon.
