These 3 ingredient flourless brownies were developed by a complete accident. I was in the midst of making a smoothie and had put some banana, cocoa powder and peanut butter into a blender. It was only then I realized that I had run out of milk.

Instead of throwing out the contents of my blender, I gave them a quick blend and was left with something that resembled batter. I decided to take a chance and transfer them to a baking pan and baked them as though they were brownies.

What resulted from this experiment was a fudgy, rich brownie-like treat, perfect to satisfy any chocolate fix or sweet tooth.

Healthy Oil-Free Brownies with Banana

The best part? These healthy brownies were 100% guilt-free!

No oil.

No sugar.

No grains.

No flour.

Low carb.

I dare you find a more guilt-free chocolate fix than this.

3 Ingredient Brownie Ingredients

You only need three ingredients to make these healthy flourless brownies with 3 ingredients.

  1. Mashed banana
  2. Cocoa Powder
  3. Almond Butter or Peanut butter 

That’s it! 

If you have a nut allergy and want to keep these nut-free, you can replace the almond butter or peanut butter with either sunflower seed butter or tahini

Optional but highly recommended- A handful of paleo and vegan chocolate chips

How to make healthy 3 ingredient flourless brownies from scratch

Step 1: You’ll start by preheating your oven to 180C/350F. Line a square pan with parchment paper and set aside. Then, add your bananas into a large mixing bowl, and mash them completely. Alternatively, you can blend them using a blender for an even smoother texture (highly recommended).

Step 2: Add your peanut butter/almond butter and cocoa powder.

Step 3: Mix your ingredients until fully incorporated. If desired, add chocolate chips to it and fold them through.

Step 4: Transfer your brownie batter into the lined pan.

Step 5: Bake your 3 ingredient brownies for 17-20 minutes, or until a skewer comes out just clean. Allow brownies to cool in the pan completely, before slicing into 9 pieces.

Do these brownies taste like banana?

I’ll be honest. These brownies are 100% healthy, guilt-free and made with incredibly healthy ingredients. They will NOT taste like traditional brownies and DO have a slight banana flavor. In fact, if you aren’t a fan of bananas, I do not recommend this recipe.

Instead, you can make these 3 ingredient pumpkin brownies or this recipe for 3 ingredient applesauce brownies. The former is even keto approved! 

Can I substitute the banana for something else? 

The banana is my favorite starch base as it is naturally sweet, and often sweet enough to make sure the brownies taste like a healthy dessert.

If you don’t want to use bananas, you can opt for one of the two brownies mentioned above or these sweet potato brownies

These brownies are not sweet at all. How do I sweeten them? 

If you taste-test the batter and find it to be not sweet enough to your liking, you can add one of the sweetener options below-

  • Liquid Stevia. Add 1 serving to your batter (5 drops) and give it a taste test. If it still isn’t sweet enough, add a few more drops. 
  • Maple Syrup. For a refined sugar-free brownie, add 1/4 cup pure maple syrup and an extra 2 tablespoons of cocoa powder. The brownies using maple syrup will be extra gooey. 
  • Agave nectar. Like maple syrup, add 1/4 cup and increase cocoa powder by 2 tablespoons. 
  • Coconut palm sugar. Add 2 tablespoons of coconut palm sugar to the batter. You won’t need to amend any of the other ingredients if you use this.

Storing healthy flourless brownies

Do NOT store flourless brownies at room temperature. The brownies are incredibly fragile and need to be stored in the fridge. 

Place cooled brownies in a sealable container and keep them in the fridge at all times. They will keep for at least 5 days.

Bonus secret tip: The brownies taste AMAZING chilled from the fridge. 

Can you freeze these brownies? 

These flourless brownies are freezer friendly and can be stored in the freezer.

To freeze, wrap the cooled brownies in parchment paper and place them in individual ziplock bags. Frozen brownies will keep for 6 months. Thaw them in the fridge overnight or at room temperature. 

Can I have these brownies on the whole30 diet? 

While these brownies contain ALL 100% whole30 approved ingredients (banana, unsweetened cacao powder, and almond butter), they are technically NOT whole30 approved. The whole30 diet promotes whole food ingredients (which these are!) but not disguised as desserts or treats.

However, if you are loosely following a whole30 diet, these could be included. 

You make the choice!

  1. The richer the better is my chocolate or cocoa ratio rule. I’m a serious cocoa snob buying only one certain brand [unless it’s for using larger quantitites in baking when my go-to would be too expensive] because it’s super dark and intense in taste.
    No workout = chunky banana brownies – now that’s a conclusion I wouldn’t have gotten ;). Fudgy brownies are best so who cares what they look like.

  2. These don’t…look…that ugly… It’s what’s inside that counts right? Perfect lesson for people. See? You did two things at once: taught a lesson on judging and made people want to faceplant all at once! That’s talent 🙂

  3. This post made me realize I didn’t have dessert all week in San Diego. That’s right, one whole week without sweets. I must be insane! Looks like I’ll have to get busy in the kitchen this weekend. I would totally go full-cocoa with these.

  4. Arman! I made your “epic” cake batter bites yesterday evening and they are SO good! 🙂 Now I feel like I might need to make these brownies so that I have chocolate to snack on in my fridge too. Hah!

  5. By far this blog has made it to the very top of my 3 page blog list I read daily! Seriously, your recipe are I love recipes that are plant-based, paleo, sugar-free, and lower in calories. As you know, that’s hard to find in a dessert-like healthy enough for breakfast type of recipe 🙂 I have converted all my clients over to reading your blog as well. I may not have ever posted a comment or may never post again (kidding), but just know I read your blog every single day!!!!! If a day goes by I don’t read, then checking your blog is on my mind like food is 24/7 haha

  6. I absolutely agree with you! Sometimes the most vile looking creations are the TASTIEST in the world while the most beautiful taste good, but just nothing special! I know from experience! 😀
    These banana brownies sound AMAZING and I’m so glad they’re only three ingredients! I can easily make them now!

  7. Oh, my vanity extends to everything, Arman. Food especially. Well, maybe Cinnabon coffee especially. Haha! Just kidding…I love the way these look! I think I would love them even more if they were stacked on a plate right next to me right now. Well done, goat-goose-man!

  8. I’ve been making so many of your recipes lately and they’re amazing!!! I want to try making these with a cup of pumpkin puree instead of the bananas and then adding stevia for the sweetener
