For a more rich chocolate taste, you can make a melted chocolate topping to pour over the Chocolate Banana Brownies. 

  • Combine 2 tablespoons butter and 2 ounces unsweetened chocolate in a large saucepan over low heat. Stir as you get softened butter and melted chocolate. 
  • Add 1 cup powdered sugar to the butter-chocolate mixture. 
  • Add little amounts of boiling water to the melted chocolate mixture to make it thinner. 
  • Pour over the brownies and let cool. 



  • Prep time: Start by preheating the oven and prepping the square baking pan. Either use cooking spray to grease the 9-inch square pan or prep it with parchment paper. Make sure to cut the baking paper to size. 
  • Wet ingredients: Mash the large bananas with a fork and melt the butter in a small bowl. Mix together the melted butter, mashed bananas, sugar, eggs, and vanilla extract in a large bowl. 
  • Dry ingredients: Sift together the flour, cocoa powder, baking powder, and salt in a medium bowl. Whisk flour mixture together. Add the dry ingredients to the wet ingredients and combine flour into the brownie batter. Then fold in half the semisweet chocolate chips for extra chocolatey brownies.
  • Bake: Pour the batter into the prepared baking pan. Use a rubber spatula to get all the brownie batter into the pan. Sprinkle the remaining chocolate chips and bake for 35-40 minutes. To test if the easy banana brownies are done use a toothpick. If the inserted toothpick comes out clean, take the brownies out, let them cool, and enjoy.

  • Flour: Instead of making Banana Brownies with all-purpose flour, you can make Whole Wheat Brownies using whole wheat pastry flour in the flour mixture. For Gluten-Free Brownies use almond flour, oat flour, or coconut flour. 
  • Vegan: To make this a delicious vegan dessert use flax eggs, a butter replacement, and dairy-free chocolate chips. Flax eggs are a great vegan replacement for eggs. You could also use applesauce or avocado instead of flax eggs. To replace the butter try coconut oil or cashew butter.
  • Sweeteners: Instead of granulated sugar, you can use brown sugar, coconut sugar, or maple syrup in the recipe. 
  • Add-ins: there are so many delicious mix-ins you can try to add to this original recipe. Mix in some chopped nuts, dried fruit, or toffee bits. You can also make Peanut Butter Brownies by mixing in some peanut butter with the Brownie Batter. For some extra flavor mix in an extra teaspoon vanilla, almond extract, or tbsp ground cinnamon. For some toppings, sprinkle sea salt, or add banana slices on top of the Banana Brownies.
  • Chocolate chips:  Instead of semisweet chocolate chips, you can use milk chocolate, white chocolate, or dark chocolate.



  • Serve: After baking the Fudgy Banana Brownies, they’ll keep well at room temperature for 3-4 days. Cover the cooled brownies in plastic wrap or aluminum foil to store in the pantry. 
  • Store: To store brownies, cut them from the square baking tin and put them in an airtight container or ziplock bag to keep in the fridge for a week. 
  • Freeze: You can also freeze Chocolate Banana Brownies for up to 6 months. Let them defrost in the fridge overnight for the perfect treat.

  1. I made your brownie banana recipe. It is excellent. Moist and very easy to prepare with everyday ingredients. I live in a high altitude state 4400 ft. and did not have to change anything. I used an 11 inch by 7 inch baking pan. Thank you for sharing.

    1. Thanks for the feedback, Leona. I’m still a novice when it comes to adapting to high altitude so I appreciate you letting me know.

  2. You saved my day. I have one very large banana sitting on my counter getting ripe. I always have unsalted butter, chocolate chips and cocoa powder in my fridge or pantry. Sounds like the perfect recipe for me. Thank you. I have made several of your recipes with very wonderful results. Tomorrow is my baking day. Thank you again.
