Banana Bread Brownies

Sharing is caring!

If you love brownies and you love banana bread, you will love this mashup dessert for banana bread brownies.

The other day my husband found a delicious dessert online that he wanted me to try. I wasn't too sure about it but he assured me this sounded like the perfect dessert.

When he told me it was for banana bread brownies, I was on board with it.

I have tasted these before at a restaurant and already knew how delicious they were, so I was all in for making a batch.

How to Make Banana Bread Brownies

These bars are so insanely easy to make and they are super moist. These are better then banana bread if you are looking for a sweet treat!

The icing is pretty sweet so, you can actually make these and not add the icing if you don’t want them too sweet and they are still so good.

We added walnuts to ours but you can also use pecans too if you want. If you are taking these to a school, you might want to leave the nuts out completely for those kiddos that have nut allergies.

If you want to freeze these, simply just cut them up and wrap them individually. Then, you can take them out one at a time for a snack instead of thawing them all at one time.

This recipe comes together in 25 minutes and is perfect to take to parties, potlucks, church dinners, or even when you need goodies for a bake sale.

We love these and we feasted on a delicious pan of these for about a week. Be sure and cut them in smaller squares and it will last longer. Because the icing is so sweet, they are very decadent so a little piece goes a long way.

Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes


for the brownies

  • 1 1/2 cup of sugar
  • 1 cup of sour cream
  • 1/2 cup butter, softened
  • 2 large eggs
  • 1-3/4 large ripe bananas mashed, 3 or 4
  • 2 tsp of vanilla extract
  • 2 cup of all-purpose flour
  • 1 tsp of baking soda
  • 3/4 tsp of salt
  • 1/2 cup chopped walnuts optional

for the browned butter frosting

  • 1/2 cup of butter
  • 4 cup of powdered sugar
  • 1-1/2 tsp of vanilla extract
  • 3 tbsp of milk


    1. Preheat oven to 375F.
    2. Grease and flour 9x13 cookie sheet.
    3. In a large bowl, beat together sugar, sour cream, butter, and eggs until creamy.
    4. Blend in mashed bananas and vanilla extract.
    5. Add flour, baking soda, salt, and blend for 1 minute.
    6. If you are going to use nuts, you can fold them in at this step. If not using nuts, just skip to step 7.
    7. Spread batter evenly into pan. Bake 20 to 25 minutes or until golden brown.

To Make the Browned Butter Frosting

    1. Heat butter in a large saucepan over medium heat until the butter begins to bubble and boil.
    2. Let the butter turn a delicate brown and remove from heat immediately. Be careful and watch it. The butter can burn quickly if not careful. The minute it starts to brown, remove it and keep stirring. It should begin to all turn brown.
    3. Add powdered sugar, vanilla extract, and milk. Whisk together until smooth (it should be thicker than a glaze but thinner than frosting).
    4. 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).
    5. Allow to sit until the frosting is cooled and hardened.

I am completely obsessed with banana bread, so this sounds perfect! I can't wait to try this. I bet it would be good with cream cheese frosting too.
