Ingredients List

  • 2 large overripe bananas (approx. 225g mashed) Why this? Higher sugar content for better flavor.
  • 1/2 cup (125g) creamy natural peanut butter Why this? Acts as the fat and binder.
  • 1/4 cup (25g) unsweetened cocoa powder Why this? Gives the classic brownie color.

Chef: If your peanut butter is the "no-stir" kind, it still works, but natural creamy versions usually produce a more decadent texture.

Tools You'll Need

No specialized equipment is necessary. Just use a medium mixing bowl, a spatula, and either a sturdy fork or a potato masher. Make sure you have an 8 inch square baking pan and a sheet of parchment paper ready.

Baking Instructions

1. Prepping the Pan

Preheat the oven to 350°F (180°C). Fit an 8-inch square pan with parchment paper, making sure the edges extend slightly over the sides for easy removal of the treats.

2. Creating the Smooth Base

Peel 2 large overripe bananas and place them in a bowl. Mash them using a fork or masher until the mixture is smooth and liquid-like and free of any large lumps.

3. Folding in the Flavor

Mix in 1/2 cup creamy natural peanut butter until well integrated. Sift in 1/4 cup unsweetened cocoa powder to avoid clumps, then stir until the batter is a consistent, mahogany-colored paste. Note: The batter should look velvety and thick.

4. The Bake

Spread the batter evenly into the prepared pan. Set the timer for 20–25 minutes until the edges are firm and the center has a slight, springy give when pressed lightly.

5. The Set

Remove the pan from the oven. Allow the brownies to cool and set for 30 minutes before slicing them into 16 squares.

Problems and Solutions

Because this is a flourless recipe, the "set" happens during the cooling phase. If you cut into them too early, they might seem underbaked.

Mushy Centers

This happens if the bananas were too watery or you pulled them out too soon. Let them cool completely or pop them in the fridge for an hour.

Bitter Aftertaste

Low-sugar bananas can make the cocoa taste sharper. Ensure your bananas are spotted brown for the best balance.

Sticking to Pan

If you skip the parchment, these can be tricky to remove. Use a plastic knife to loosen the edges.

Storage and Freezing

Store these in a closed container in the fridge for up to 5 days. They are often better chilled, as this allows the fudge-like center to firm up.

For a longer shelf life, freeze the squares individually on a baking sheet. Once solid, transfer them to a freezer bag where they can be kept for up to 3 months.

To reheat, microwave a frozen square for 15–20 seconds until the center is soft.

Best Pairings

I like serving these with a dollop of coconut cream or a handful of fresh raspberries. The brightness of the berries cuts through the rich peanut butter. A glass of cold almond milk is also a wonderful match.

Why It Works

To get a rich, fudgy texture, these simple 3-ingredient banana brownies rely on a few clever tricks.

  • Fruit-Based Body: Overripe bananas offer starches that replace flour, resulting in a moist, dense crumb.
  • Nut Butter Binding: The fats found in peanut butter act as a binder, removing the need for eggs.
  • Inherent Sugars: Because starch turns into sugar as the fruit ripens, no added sweeteners are necessary.

Your Questions, Answered

Can you replace eggs with bananas in brownies?

Yes, this recipe does exactly that. Bananas act as the natural binder and moisture source to replace eggs.

What are the ingredients for these flourless brownies?

They require overripe bananas, creamy natural peanut butter, and unsweetened cocoa powder. Only these three items are needed for the batter.

Are these 3-ingredient banana brownies healthy?

Yes, they use whole-food ingredients. This version avoids refined sugars and flours.

Could I make this without peanut butter?

Yes, you can use another nut or seed butter. This maintains the fudge-like consistency while altering the flavor.

How to store the brownies?

Keep these refrigerated in a sealed tub for up to 5 days. Chilling them actually improves the taste by firming up the fudge-like center.

Why do they feel too soft after baking?

Skipping the cooling period often causes this. Let the brownies cool completely in the pan for 30 minutes to set before slicing.

How long can they stay in the freezer?

Up to 3 months in a freezer bag. Freeze individual squares on a baking sheet first to prevent them from sticking together.
