3 Ingredient Brownies (No flour or eggs!)- The Big Man's World (2024)

These 3 ingredient brownies are a healthy and easy chocolate dessert recipe that bakes in just 20 minutes! There is no flour or eggs needed.

Healthy desserts with just a handful of ingredients? Count me in.

If you’ve tired our sugar free cookies, protein mug cake, or flourless mug cake before, you will adore this recipe.

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.

Recipe highlights

I call these brownies my guilt-free chocolate fix and make them at least once a week!

• No flour or grains. Unlike coconut or oat flour brownies, these don’t have any of the basics.
• Healthy. Bananas and peanut butter are two of the healthiest foods ever, and unsweetened cocoa powder is just perfection.
• Ready in 20 minutes. From prep to plate, these brownies bake in less than 20 minutes.

How to make 3 ingredient brownies

When baking these brownies, I recommend choosing a baking dish or pan that is typically smaller than what you’d use for traditional brownies. This way, you’ll be left with thicker and richer brownies that are just that much more satisfying to eat.

The instructions

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 to 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 them into 9 pieces.

Dietary swaps and substitutions

This brownie recipe is actually pretty easy to adapt to a plethora of diets or food preferences out there. Here is what we’ve personally tried (and can vouch for!).

• Swap out the banana. If you aren’t a fan of bananas, you can use unsweetened applesauce or pumpkin puree. Be wary though, the brownies won’t be as sweet. To compensate, add 1/4 cup of sugar or a liquid sweetener, like maple syrup.
• Use another nut butter. Almond or cashew butter will work well.
• Make these nut free. Tahini or sunflower seed butter instead of the peanut butter.
• Add frosting. I love to add a thick layer of my 2 ingredient or healthy frosting.

Storage instructions

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

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.
