Ingredient Breakdown

What You’ll Need

3 ripe bananas (about 1 cup mashed): The riper, the better! Think brown spots. They add natural sweetness and moisture to the brownies.
120 grams (1/2 cup) creamy peanut butter: This is the big flavor contributor! Feel free to substitute almond butter or any nut butter you have on hand if you’re feeling adventurous.
50 grams (1/2 cup) cocoa powder: This is what gives these brownies their delightful chocolaty goodness!

If you want to get creative, add some chocolate chips, or a couple pinches of salt for an even richer flavor. The best part is you can easily customize this recipe!

Let’s Get Cooking!

Preheat your oven to 180°C (350°F). Grab a 15 cm x 15 cm (7 inch x 7 inch) brownie pan and line it with parchment paper. Gotta save ourselves from a sticky situation!
Mash your bananas. In a large bowl, mash the 3 ripe bananas until they are silky smooth. Make it fun! You can even let the kids help with this part! The smell is just divine, I tell you!
Mix in your peanut butter. Once your bananas are mashed, add the creamy peanut butter and stir the mixture until everything is smooth. It will become creamy and luscious, like a dream!
Sift in the cocoa powder. Next, sift in your cocoa powder and mix until fully combined. You’ll want to make sure it’s all incorporated. Scrape the yummy bits off the bottom of the bowl!
Transfer to the pan. Now, pour your brownie batter into the prepared brownie pan, spreading it out evenly. I like to use a spatula to help!
Bake! Pop those beauties in the oven and bake for 22 to 30 minutes. Mine took exactly 27 minutes. You’ll know they’re done when the top looks firm and a toothpick inserted in the center comes out mostly clean. Just a couple crumbs are okay, trust me!
Cool and slice. Let the brownies cool completely at room temperature before slicing into them. You want to enjoy every gooey bite, not burn your mouth off.
