Ingredient Notes

Ingredients required for 3-ingredient banana brownies recipe.
  • Overripe bananas: Very ripe bananas are the secret to this 3 ingredient brownie recipe. Spotty bananas are soft and sweet, adding moisture and sweetness to this healthy dessert recipe.
  • Peanut butter: You can use peanut butter or any nut butter, like cashew butter, almond butter, etc. Ideally, look for a natural nut butter that contains just nuts on the ingredient list (a bit of salt is fine too).
  • Cocoa powder: Use regular unsweetened cocoa powder for the best results.
  • Chocolate chips: These are optional, but we love the bite and touch of extra sweetness you get from sprinkling chocolate chips on top! They’re a great way to satisfy a sweet tooth with minimal sugar.

How to Make 3-Ingredient Brownies with Cocoa Powder

  1. Preheat oven to 350 degrees F. Line a muffin tin with silicone baking cups or spray really well with cooking spray. Alternatively, you can line an 8×8 square baking pan with parchment paper.
  2. Puree the bananas in a food processor until smooth. Next, add the peanut butter and cocoa powder and process until well combined.
  3. Evenly distribute the mixture among 12 cups in the muffin tin or pour it into a lined baking pan. Sprinkle the surface of the brownies with chocolate chips if desired.
  4. Bake for 20-25 minutes or until the edges and the top are slightly firm and the brownies are well risen. Allow the brownies to fully cool before removing from the pan.

RECIPE TIPS

  • These chocolate banana brownies are not overly sweet since they’re only sweetened with bananas. Taste a bit of batter before baking and adjust the sweetness as needed. If you prefer your brownies on the sweeter side, you can add a few tablespoons of coconut sugar, brown sugar or maple syrup to the batter, or additional chocolate chips. You can also top them with this naturally sweetened frosting which will add some nice sweetness as well! 
  • These brownies are not like your typical brownie as they don’t have that same cake-light consistency. They’re more soft, moist and fudgy and have a chocolate banana flavor. If you don’t like bananas, you probably won’t be a fan of these brownies. 
  • Allow the brownies to fully cool before removing them from the muffin/baking pan. They’ll seem soft when they first come out of the oven but will firm up more as they cool.
  • You may wish to add a pinch of salt, vanilla extract and half a teaspoon of baking powder for some extra flavor.

Recipe FAQs

Are brownies healthy for kids?

Regular brownies are often loaded with carbohydrates, sugar, and saturated fat, making them utterly delicious, but not the most nutritious choice. Like anything else in life, you can certainly serve traditional brownies in moderation.

However, if you’re looking to limit added sugar, I highly recommend making these 3 ingredient brownies to offer a sweet treat that actually supports your children’s dietary needs. This recipe will satisfy any chocolate cravings without spiking their blood sugar.

As a bonus, if they haven’t been served much sugar before, they’ll appreciate the natural sweetness in this healthy brownie recipe.

Can babies have brownies?

It’s recommended that little ones do not consume added sugar before the age of two, so regular brownies aren’t typically the best option for them.

Instead, offer them naturally sweetened peanut butter banana brownies that are rich in healthy fats to support their growing brains and bodies! 

Can you freeze leftover brownies?

Absolutely! The great thing about brownies (besides their taste) is that they’re easy to store for later. You can freeze them in a freezer-safe bag, then pull out exactly how many you need to thaw in the fridge. This makes it so much easier to include them in lunch boxes or serve them as a dessert.

  • You can also freeze them in a freezer-safe bag for several months. Be sure to thaw leftovers in the fridge before serving.

Serving Suggestions

These healthy brownies with banana are wonderful served as a snack or as part of a healthy meal.

To make them more filling, pair them with any of the following options:

Recipe Variations

  • Add dark chocolate chips: Add a little extra texture and sweetness with a sprinkle of dark chocolate chips in the brownie batter.
  • Brownie bites: You can either cut this banana brownie recipe into small bites or bake them in mini muffin tins for a perfect bite-sized treat.
  • Nut-free vegan brownies: Instead of peanut butter, add sunflower seed butter to get the same fudgy texture without any nuts.
