What you need for 3-ingredient brownies

Scroll down to view the recipe card below for the full ingredients list, nutrition facts, and step-by-step instructions.

• Very ripe bananas  – The riper the better! Look for bananas that are heavily speckled or mostly brown. Overripe bananas provide natural sweetness, moisture, and structure since there are no eggs or flour in this recipe.
• Natural peanut butter – Use a creamy, drippy natural peanut butter made with just peanuts (and salt if preferred). Well-stirred peanut butter blends smoothly into the batter and helps create that rich, fudgy texture. You can also substitute almond butter, cashew butter, or sunflower seed butter.
• Cocoa powder – Unsweetened cocoa powder gives these 3 ingredient banana brownies their deep chocolate flavor. You can also use raw cacao powder as a 1:1 swap for a slightly richer taste.

How to make vegan brownies

Step 1: Preheat the oven to 350 degrees F.  Line a square 8×8 baking dish was parchment paper.

Step 2: In a large bowl add the overripe bananas and mash well.  You don’t want any pieces of banana left in there.

Step 3: Add the peanut butter and cocoa powder to the mashed banana mixture and mix well – you will have a thick batter.

Step 4: Spread the brownie batter into the prepared baking pan and bake brownies in preheated oven for 17-20 minutes, or until the top looks cooked through.

Step 5: Allow this easy brownie recipe to fully cool on a wire rack before cutting into.

NOTE – Instead of mashing the banana, you can blend it up in a food processor or blender for super smooth mashed bananas.

Bananas –  What if you don’t like the taste of bananas? Swap the banana for cooked mashed sweet potato or yams and add 2-3 tablespoons of maple syrup into the mix.

Peanut butter – As mentioned above, any nut or seed butter works in place of peanut butter. If you need to make a nut-free recipe, use sunflower seed butter or tahini. If nuts are okay, try almond butter, cashew butter, walnut butter, or pecan butter.

Frequently asked questions

Are 3 ingredient banana brownies actually healthy?

Yes! These 3 ingredient banana brownies are made with whole food ingredients – ripe bananas, nut butter, and cocoa powder – with no eggs, no flour, and no added sugar. While they’re still a treat, they’re naturally sweetened, gluten-free, and packed with healthy fats and fiber from the nut butter and bananas. They’re a much more nourishing option compared to traditional brownies loaded with refined sugar and flour.

Do these banana brownies taste like bananas?

Yes, they do because bananas are the main ingredient, so you’ll taste a mild banana flavor in these brownies. If you love banana bread, you’ll love these!

Can I make 3 ingredient banana brownies without peanut butter?

Absolutely! You can swap the peanut butter for:

• Almond butter
• Cashew butter
• Sunflower seed butter (great nut-free option)
• Tahini

Any creamy nut or seed butter works. Just be sure it’s well-stirred and not overly dry.

Can I make these banana brownies nut-free?

Yes! To make nut-free 3 ingredient banana brownies, use sunflower seed butter or tahini instead of peanut butter. Both give great texture and still create that fudgy consistency.

Why are my banana brownies too soft or undercooked?

These brownies are naturally fudgy and soft – they won’t have the same structure as traditional flour-based brownies.

If they seem too soft:

• Make sure they’re fully baked (the top should look set).
• Let them cool completely before slicing. They firm up significantly as they cool.
• Store them in the fridge for the best texture.

How ripe should the bananas be?

Very ripe! The bananas should be spotty brown and soft. The riper the banana, the sweeter your three ingredient banana brownies will be. If your bananas aren’t ripe enough, the brownies may not taste sweet.

Can I make these in a different pan size?

Yes! An 8×8 pan gives thick, fudgy brownies.

If using:

• A 9×9 pan → They’ll be thinner and may bake a little faster.
• A loaf pan → Baking time may need slight adjustment.

Keep an eye on them and look for a set top.
