Hi Bold Bakers!

Chocolate and banana is a truly underrated flavor combination. The bitterness of the chocolate helps balance the sweetness of the banana, and in this banana bread brownie recipe, those bananas should be extra ripe and extra sweet! 

This homemade banana bread brownie recipe is rich and wonderfully moist — no dry brownies here. I would say this recipe yields a dessert that is more like a brownie than banana bread, texture-wise. 

While I love a good banana bread, sometimes you do have to mix things up a bit! This is a perfect recipe to use up those bananas you have laying around, or stuffed in your freezer.

What Are Banana Bread Brownies?

Banana bread brownies are an incredible combination of two flavors I love. It’s part banana bread, part brownie. You essentially are making two bowls of different flavors, then combining them in one pan to bake. The texture is chewy and moist, like brownies. 

What You Need To Make Banana Bread Brownies

How Do I Make Banana Bread Brownies

These unique brownies are very easy to make and the final product looks (and tastes) beautiful. Here is how you make banana bread brownies (get all the measurements down below):

  1. First, preheat your oven to 350°F (180°C) and butter and line an 8×8-inch (20x20cm) baking pan.
  2. Combine the flour, baking powder, and salt in a medium mixing bowl.
  3. In a separate mixing bowl, whisk the butter, sugar, eggs, and vanilla extract together. 
  4. Combine the wet and dry ingredients and then divide the batter evenly into 2 separate bowls.
  5. In one bowl, stir in the cocoa powder and chopped chocolate. In the other bowl, stir in the mashed bananas.
  6. Pour the banana batter into your prepared pan. Then, dollop heaping scoops of the chocolate batter randomly over the banana batter.
  7. Take a butter knife and swirl the chocolate batter through the banana batter. Don’t mix it completely, we’re creating a marbled look.
  8. Bake for 40-45 minutes until a wooden skewer inserted in the middle comes out clean. Allow the brownies to cool completely before cutting.

Gemma’s Pro Chef Tips For Making Banana Bread Brownies

  • As always, the riper the banana the better! That goes for any sort of banana bread you are baking.
  • Instead of bittersweet chopped chocolate, you can use milk or white chocolate if you prefer.
  • For more texture and flavor, add a ½ cup (2½oz/71g) of chopped toasted walnuts or pecans to the banana bread portion of the batter.
  • When you are swirling the batters together, use a light touch so you don’t overmix the batter and lose the marbled effect.
  • Make banana bread brownie sundaes with my homemade vanilla ice cream and salted caramel sauce or hot fudge.
  • You can double this recipe and bake it in a 9×13-inch (23x33cm) pan for a larger crowd. The baking time will be a bit longer – just keep an eye on it and text with a skewer until done.

How Do I Store Banana Bread Brownies?

You can store leftover brownies in an airtight container at room temperature for up to 3 days. You can also freeze these brownies for up to 2 months. Defrost them at room temperature or in the microwave for a minute before serving.

So I’m thinking to myself, self, it is time to start thinking about what you are going to bake for everybody as Christmas gifts. Husband says, there you go thinking again.   Since we grow our own bananas, I’m going to make banana bread, again, again, and again.   “No Can” ( Hawaiian version of “No Way”)    So I am saying Mahalo in advance. This is an unbelievably good recipe! I made a double batch because if I’m going to turn the oven on using the most expensive electricity in the United States, I’m going to make a double batch. … Read more »

This was fantastic!!!!!!! Brilliant idea! I made them gluten free by using an all-purpose gluten free flour (Namaste brand that our local Costco carries).
We always like our banana bread with brown sugar, cinnamon, and nutmeg so I used those, but otherwise followed the recipe. I also used chocolate chips because that’s what I had.

This worked out perfectly. My sister-in-law is gluten free and vegan, so next time I will experiment with egg replacers. But this was a delightful treat that was easy to make gluten free.

Also wound up with a greater percentage brownie (when compared to the pictures) but not a problem. Moist and delicious. The recipe is a keeper!

I have tried a lot of your baking recipes and my family loves it.

These were AWESOME. I made them dairy free by substituting canola for the butter, and using Ghirardelli dark chocolate pieces. I doubled the recipe, baked it in a 9×13 stone pan at 325° for 45 mins.

The picture shows what looks like a few chocolate chips melted on top? What are the small, perfectly “round” pieces on the brownie top?
