Ingredients

  • ¼ cup unsweetened cocoa powder

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

Directions

  1. Preheat the oven to 350°F (175°C). Line an 8x8-inch baking dish with parchment paper.

  2. In a large bowl, mash the ripe bananas until smooth.

  3. Add the peanut butter and cocoa powder to the mashed bananas and mix until fully combined. The batter will be thick.

  4. Spread the batter evenly into the prepared baking dish.

  5. Bake for 17-20 minutes or until the top appears cooked through.

  6. Allow the brownies to cool completely on a wire rack before cutting into squares.

Servings and Timing

  • Servings: About 9-12 brownies

  • Preparation Time: 5 minutes

  • Cooking Time: 17-20 minutes

Variations

  • Nut butter substitutions: Swap peanut butter for almond butter, cashew butter, or sunflower seed butter for a different flavor.

  • Add-ins: For extra chocolatey goodness, add chocolate chips to the batter before baking.

  • Sweet potato option: If you're not a fan of bananas, you can substitute mashed sweet potatoes or yams for the banana.

Storage/Reheating

  • Storage: Once cooled, store brownies in an airtight container in the fridge for up to 5 days.

  • Freezing: Freeze brownies by placing them in a freezer bag, separated by parchment paper. They will stay good for up to 6 months. Thaw on the counter before enjoying.

FAQs

Can I use any nut butter for this recipe?

Yes, almond butter, cashew butter, or sunflower seed butter work well as alternatives to peanut butter.

Can I make these brownies without cocoa powder?

Yes, you could substitute with raw cacao powder or even try adding melted dark chocolate for a different texture and flavor.

What if I don’t have ripe bananas?

For the best results, use overripe bananas as they provide the necessary sweetness and moisture. If not available, you can try adding a bit of honey or maple syrup to compensate.

Can I add chocolate chips to the brownies?

Absolutely! Adding chocolate chips will enhance the chocolate flavor and make these brownies even more decadent.

How do I know when these brownies are done?

The brownies are done when the top looks set and no longer glossy. You can also test by inserting a toothpick into the center—it should come out clean or with a few moist crumbs.

Can I make these brownies without peanut butter?

Are these brownies vegan-friendly?

Yes, this recipe is vegan, as it contains no eggs or dairy.

Can I make these brownies in a different-sized pan?

If you use a larger pan, the brownies may be thinner, and the baking time might need adjustment. Keep an eye on them while baking.

Can I use frozen bananas for this recipe?

Yes, frozen bananas will work as long as they are thawed and mashed well before mixing with the other ingredients.

How can I make these brownies sweeter?

If you'd like the brownies sweeter, you can add a small amount of maple syrup or honey to the batter.
