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 than banana bread if you are looking for a sweet treat!

The icing is pretty sweet, 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, if you want. If you are taking these to a school, you might want to leave the nuts out completely for those kiddos who have nut allergies.
If you want to freeze these, simply 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 to cut them into smaller squares, and they will last longer. Because the icing is so sweet, they are very decadent, so a little piece goes a long way. You could even use this brownie pan for the perfect brownie every time.

Banana Bread Brownies
These banana bread brownies are absolutely delicious and so easy to make.
Ingredients
for the brownies
- 1 ½ cup of sugar
- 1 cup of sour cream
- ½ cup butter, softened
- 2 large eggs
- 1-¾ large ripe bananas mashed, 3 or 4
- 2 teaspoon of vanilla extract
- 2 cup of all-purpose flour
- 1 teaspoon of baking soda
- ¾ teaspoon of salt
- ½ cup chopped walnuts optional
for the browned butter frosting
- ½ cup of butter
- 4 cup of powdered sugar
- 1-½ teaspoon of vanilla extract
- 3 tablespoon of milk
Instructions
- Preheat oven to 375F.
- Grease and flour 9x13 cookie sheet.
- In a large bowl, beat together sugar, sour cream, butter, and eggs until creamy.
- Blend in mashed bananas and vanilla extract.
- Add flour, baking soda, salt, and blend for 1 minute.
- If you are going to use nuts, you can fold them in at this step. If not using nuts, just skip to step 7.
- Spread batter evenly into pan. Bake 20 to 25 minutes or until golden brown.
To Make the Browned Butter Frosting
- Heat butter in a large saucepan over medium heat until the butter begins to bubble and boil.
- 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.
- 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).
- Allow to sit until the frosting is cooled and hardened.

I love banana bread and I love brownies! I cannot wait to bake this up!
Yum! I'm not sure I've ever tried browned butter frosting, but I'm intrigued!
What a different way to serve banana bread. That frosting sounds so yummy
Oh, boy, do these look good! I love banana bread but never imagined it in brownie form. I absolutely need to try these. I have everything to make them in the house except bananas, so as soon as I pick those up, I'll give them a go.
You've basically taken two of my favorite things and combined them into one recipe. I can't wait to try these.
I recently made these without the frosting and they were so good. I just cannot keep bananas around long enough for them to ripen.
You just named two of my mom's favorite desserts. I really have to try and make this for her - she's been feeling a little down lately so I'm hoping this will brighten up her days!
These look amazing! I need to make them. They sound delicious. I love banana bread, so I'm sure I'll love this too.
YUM! I just made banana nut bread this morning. I like your idea better.
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.
I have very ripe bananas waiting to be made into something. I'm glad I found this recipe!
Oh wow. My sister would love this! I can't wait to make some for her.
Awesome. The best of both worlds! I am going to be busy in the kitchen this weekend with all the yummy recipes I have saved. I am going to start with your banana bread brownie recipe. That sounds so delicious!
