These fudgy Triple Chocolate Peanut Butter Banana Brownies are rich and chewy! Each bite has a triple dose of chocolate, a hint of banana and a swirl of peanut butter! Your new favorite way to use over-ripe bananas!

Raise your hand if you have some sad, spotty brown bananas at home.
Raise your hand if you are sick of banana bread.
[Put your hand down! Unacceptable. Banana bread is life.]
Raise your hand if you already made banana bread and *still * have browning bananas way past their prime.
[It’s okay. This is a safe space. Me too. ]

Enter Triple Chocolate Peanut Butter Banana Brownies!
Banana BROWNIES?!! Yeah.

Chocolate; Peanut Butter; Banana: the trifecta of awesome.
I took one of my all time favorite combos and stuffed it into a brownie.
You’re welcome.

These are rich, fudgy brownes. No light cakey stuff around here.
No ma’am.
The bananas make these extra moist and super fudgy. So much so they almost seem under-baked, but they aren’t. They are just to die for chewy. And we all need some of that in our lives!

These brownies have that beautiful crispy top and soft, chewy interior. The swirls of peanut butter are the only interruption to the triple chocolate brownie perfection.
These decadent brownies have both cocoa powder and melted chocolate in the batter AND, in case that just wasn’t chocolatey enough for you (when is it ever, honestly?), some extra chocolate chips are studded throughout.
The banana flavor is present but not overpowering. In each bite you get serious chocolate, banana and a little bit of the peanut butter swirl. Oh and a sprinkle of Maldon sea salt just to finish it off.
Salty, sweet, rich, chewy and creamy. Good stuff, guys. Good stuff.

You know what else is kinda cool about these brownies? Eggs are the only leavening. It makes the combination method a little bit interesting, but the results are pure bliss.
Triple Chocolate Peanut Butter Banana Brownies
Ingredients
- 2¼ cup Semi-Sweet chocolate (chopped)
- 1 cup butter
- 2 teaspoons vanilla
- 1 cup + 2 tablespoons All-Purpose flour
- ¼ cup cocoa powder (I used Dutch processed)
- 1 teaspoon kosher salt
- 2 ⅓ cup granulated sugar
- 6 eggs
- 1 ¼ cup ripe bananas (smashed or 3 bananas)
- ½ cup chocolate chips (mounded)
- ½ cup peanut butter (slightly warmed)
- Flaked sea salt for sprinkling
Instructions
- Preheat oven to 350°. Grease and line a 12 inch by 16 inch sheet pan with cooking spray or butter.
- In a medium bowl combine flour, cocoa powder and salt; whisk to combine and set aside.
- Combine chopped chocolate, butter and vanilla in a heat-proof bowl over a pot of simmering water; heat until just melt (you don’t want it hot) and set aside. Do not begin the eggs until the chocolate is almost melted.
- Add eggs and sugar to the bowl of a stand mixer fitted with the whisk attachment. Beat until pale and fluffy on medium-high speed. This is your leavening, so don’t under beat them.
- Turn off the mixer, removed the bowl and pour the chocolate in all at once; fold in the chocolate with a large spatula. Fold in the bananas.
- Sift the flour mixture into the bowl and fold into the egg mixture until it is still a little streaky.
- Add the chocolate chips and fold to incorporate. Spread evenly in the prepared pan with an offset spatula.
- Drop the peanut butter onto the batter and swirl with a skewer, toothpick, knife or your offset spatula.
- Bake 30-40 minutes or until a toothpick comes out clean. Sprinkle with flaked sea salt and allow to cool before removing from the pan.
I wasn't sure about these brownies since I didn't see reviews from anyone who actually MADE them. But I did - using GF flour and some unsweetened chocolate melted in with the semisweet - and these brownies ROCKED!! The recipe made a big batch and my husband and I were VERY happy about that. We added a little extra peanut butter on top too. We froze about half of them to savor later. Mmmmmm!
Thanks for the recipe - it's a keeper!
Hi Stacey, I'm so glad you loved them! Good to know they work with GF flour too! Extra peanut butter never hurt anyone! You are most welcome! Happy baking!
Hi thanks for sharing this recipe
I would love to try these brownies but wanted to use Nutella also or instead
Do you think this would work? And if so, do you have any idea as to how you would incorporate it?
Thanks
Paula
Hi Paula! Just swirl the nutella on top at the end instead of the peanut butter! It will work perfectly! Happy baking!
MMMMMMMM8 Amazing superb photos, so attractive too! What a fabulous recipe, I have to say that!
Waw!!!
This certainly is a very delicious way to use up some bananas! I'm loving the peanut butter swirls!
You'll judge me... but I don't like banana bread that much. Or banana flavored anything for that matter. BUT... I love bananas. I have one every single day at work. Unless they are too brown, in which case I don't like them. I know, I'm weird. I hope we can still be friends. However, surround bananas with chocolate and PB... totally legit and I'll eat the whole batch. We should probably test it out though. So make me a batch of these 😉
Say what now?! Just when you think you know someone...I guess we can still be friends but I'm a little shaken. 😉
I also feel like I need to force you to try my banana bread. Just to be sure you aren't mistaken. It has a sugar on the outside. Sugar, Chris. Sugar.
Hahaha, I know, right! We all have skeletons in our closet... and I will be happy to try your banana bread. Perhaps after that ramen that you've been dying to try HAHA
Haha! Fine you win. Banana bread then Ramen 😉 But not "burn your face off" ramen because I think we should take baby steps
This is perfect! I ALWAYS have so many over ripe bananas in the house. And with those over ripe bananas come fruit flies. I can't wait to try these!
EEEEEEEEEEEEEEEEEEEEEEEE these brownies are heaven! I love choc + pb + bananas and these brownies look suuuuuper moist!
OMGosh, I'm sitting here thinking that I wish it was my fork digging into these. This looks fantastic Lindsey!
Love the beautiful look of those gooey brownies. And thanks for all the extra recipes for using up bananas. I have a big bag full of them in my freezer right now. I can see what I'll be doing today!
Yum! I totally love anything with peanut butter and banana!
Wow - these are mesmerizing - your photos are phenomenal -especially that first one - ooh - these brownies are sheer decadence! Love love love the nanners in them and Lindsay, you are spot on - there can never ever be too much chocolate in brownies! Yay for the sprinkling of the chips!
Thank you, Shashi!!!! They really are total chocolate decadence!
Wow those brownies look incredible! So many flavors to love in here 🙂 Love the peanut butter swirls on top!
Thanks, June! Can't go wrong with peanut butter!
Ahhh these look so fudgy!! You are killing me over here! Good thing I have some overripe bananas...
Phew! Good thing! Enjoy, Kristi!
These brownies look perfect! I always have sad spotty bananas and I love how amazing texture is! Anything salty and sweet is a winner in my book 🙂
Me too, Kelly! I cannot get enough salty sweet these days!
I'm sold on this Lindsey, and I almost always have brown bananas staring me in the face. I have to toss them in the freezer because there are too many to deal with sometimes! These look delicious and I love those pretty peanut butter swirls. 🙂
I definitely am guilty of the freezer trick too! I don't even want to know how many I have lingering back there lol! More than I can use in smoothies, thats for sure! 😉
Bananas in brownies?? Say what? How have I lived my life without ever making these? Hmmm...I need to get up right now and make a batch. And since bananas are healthy, that means I can eat a whole batch, too, right? 🙂
I love how you and I are *always* on the same page - there are bananas which makes these brownies totally healthy! There would be no judgement coming from me if you ate the whole batch!
These must be good. Chocolate, banana, peanut butter. Any combination of any of those ingredients is delightful.
Couldn't agree more, Karen!
What a good IDEA!!! Now I am thinking blondie, PB, banana, and fluff! (Where is the banana in the recipe - did I miss it?)
Oh a pb, banana, and fluff blondie sounds divine, Stephanie! I just updated the recipe with the banana. I don't know how that got cut off when I copied it from Word. Have a fantastic Sunday!
These brownies look and sound incredible! And your photos are beautiful. X
Thanks, Jess!
How many bananas are needed for the Triple Chocolate Peanut Butter Banana Brownies? I think they've been missed off the ingredients list.
Good catch, Anne Marie! I don't know how that happened when I copied it over. You will need 1 1/4 cups mashed bananas, which is 320g or 3 medium bananas. Sorry about that! Happy baking!
