These 3 ingredient banana brownies only take a few minutes to make! They are fudgy and chocolatey and are sweetened with just bananas!
We go through a bunch of bananas in my house and I wanted to find a way to use up some extra ripe ones before they went bad. This recipe is so simple to make with only three ingredients! They contain no flour, butter, or sugar but still come together to form a moist, naturally sweet treat! You can add in extra ingredients to customize and make them your own, but these three ingredients make the base of this healthy treat!

What You’ll Need
Here’s what you’ll need to make these 3 ingredient banana brownies:
- Banana: The main source of sweetness for these brownies. Be sure to use bananas that are overripe and have several brown spots. The riper the banana, the sweeter the brownies!
- Peanut Butter: For added flavor and texture in these brownies. Peanut butter adds healthy fats, but may be replaced with a nut-free alternative.
- Unsweetened Cocoa Powder: For that chocolatey flavor!
Step By Step Instructions
- Puree the bananas until smooth. Pour this mixture into a bowl.
- Add the peanut butter and unsweetened cocoa powder to the bowl.
- Mix until combined and fold in any additional add-ins.
- Transfer to a pan and bake for 20-25 minutes.
Optional Add-Ins
- Chocolate chips
- Chopped nuts
- Butterscotch chips
- Nut butter drizzle
- Crushed pretzels
Ingredient Substitutions
- Peanut butter: The peanut butter may be replaced with any nut butter or seed-based butter.
- Cocoa powder: The unsweetened cocoa powder may be substituted with equal parts carob powder, but be mindful that this substitution will add some sugar to the recipe.
Storage Instructions
Once cooled, store the brownies in an airtight container in the refrigerator for up to 5 days. Transfer immediately to the fridge after cooling. To freeze, store in a freezer-safe Ziploc bag. I like to section off servings and place parchment paper between each piece to prevent sticking.
Recipe Notes
- These brownies do not taste like your typical brownie since they are egg-free, gluten-free, and dairy-free, but they are pretty good for something that is banana-based! If you do not like the taste of bananas, I would not recommend this recipe.
- These brownies are meant to be soft and fudgy. If you prefer something a little thicker and cakier, try adding a little flour to the batter.
- Do not cook the brownies for more than 25 minutes. They may look like they are not cooked through, but they will continue to harden a little as they cool.
- Use overripe bananas for more sweetness. Taste the batter before baking to see if you like the taste (since the batter does not contain eggs, it is safe to taste raw). Add in a little maple syrup if you prefer more sweetness.
- The cocoa powder does contain some caffeine, so be mindful of that when deciding whether to serve to a younger child.
- I love using this nutribullet blender to blend the bananas into a smooth texture!

Yes Lily, please let me know for the measurement of flour about 8 pieces in gram ? What kind of flour for this brownie is the best like the wholewheat flour, the chickpea flour and the cake flour that I have. Thx again.
Hi Janice! I haven’t experimented with adding flour to these brownies, so I’m not sure how much would be needed or how they’d affect the texture, but you can probably try this recipe for brownie muffins instead if you’re looking for more of cakey consistency, it uses almond flour as the base and might be more of a texture you’re looking for😊

Can I substitute the smooth peanut butter to PB2? If so, would you please give me the measurement in gram & thank you.
Hi Janice! I don’t have experience with using PB2, so I’m not sure how’d it’d work here, unfortunately.
Thanks so much Lily, so delicious with PB2 !!! Would you please tell me how much wholewheat flour that I can add in gram for making cakes ?
Lily, how much PB2 did you use? I am doing Weight Watchers and this would make a nice low point snack for me!
Thx Lily, would you please tell me how many wholewheat flour to add in for 8 pieces in gram?
