Move over regular brownies! Once you try banana in brownies, you may never go back.

The bananas in this recipe keep the brownies incredibly moist, and the sweetness of the bananas balances the richness of the chocolate perfectly.

These are not like your average brownies made from brownie mix. These made-from-scratch brownies with bananas are on another level of chocolatey goodness with more than a hint of banana. We could actually nickname these banana bread brownies!

I am a huge banana lover, and also a huge fan of decadent brownies. Combining the two together in these chocolate banana brownies makes the perfect sweet treat.

Mashed banana is added to the brownie batter which gives the brownies their banana flavor, while also giving them the perfect texture. Chocolate chips are added to the batter to give even more of a chocolate flavor.

Prep bananas. Mash bananas and measure 1 cup.

Prep oven and pan. Preheat the oven to 350°F. Line a 8-inch square pan with baking parchment paper, or spray with non-stick cooking spray. Set aside.

Make chocolate mixture. In a large microwave-safe bowl, combine the butter and 4.5 oz semi-sweet chocolate bar or chips. Microwave in 30 second increments until just melted, stirring each time. Mix until smooth and well combined.

Mix wet ingredients. Add the brown sugar, eggs and mashed bananas to the chocolate mixture. Mix until well combined.

Tips for the Best Banana Brownies

Load it up with chocolate chips. Extra chocolate chips can be scattered over the brownies just before baking.

Use ripe bananas. Using overripe bananas will give your brownies a stronger banana flavor.

Clean cuts for perfect brownie squares. Use a sharp, skinny knife to cut the brownies into squares. For clean cuts, wipe the knife completely clean between each slice.

Substitutions & Variations

  • Gluten Free Banana Brownies. Make these gluten-free by subbing all-purpose flour. I recommend King Arthur’s Measure for Measure All Purpose Gluten Free Flour.
  • Make them nutty. Add in 1 cup of chopped pecans or walnuts.

Storing & Freezing Suggestions

Store brownies in an airtight container in the fridge for up to 5 days. Fridge storage is recommended because the brownies are so moist.

These brownies can also be frozen. Slice and freeze in an airtight container or bag for up to 3 months. Thaw in the fridge overnight.

FAQs

How do I make banana brownies firmer?

For firmer, less fudgy brownies, increase the bake time.

What makes brownies fudgy vs cakey?

If you more fudgy brownies, you need a higher fat-to-flour ratio. This recipe does that with butter and chocolate. Cake-like brownies have more flour and typically have baking powder.

What is the key to fudgy brownies?

The secret to making these perfectly fudgy brownies is the addition of chocolate chips melted with butter, which creates a thick, molten base. Another way to make sure your brownies come out fudgy is to remove them from the oven before a toothpick comes out clean. You’ll end up with a center that is ooey-gooey and fudgy.

Can bananas be too ripe for banana brownies?

Overripe bananas are perfect for brownies, unless your brownies are past overripe to the point where they are molded or have started to liquefy. Spotty bananas that are a little overripe actually have a bolder banana flavor that are perfect for baking.
