Chocolate + Banana = a Match Made in Heaven
To be honest, I'm not the biggest fan of fruit plus chocolate together. I know, I know! I should really give it another try, but believe you me, I have and I don't know why, but it's just not my thing. (Hope you still like me despite this obvious flaw in my tastebud preferences!)
Chocolate and banana, on the other hand, is clearly an exception. This pairing is one of those quintessential flavor combos that just makes everyone smile. So, in trying to redeem myself with you all, I will now share a delicious and super easy to bake recipe that highlights these flavors so well.
How to Make Marbled Chocolate Banana Bread
Putting this chocolate banana bread recipe together is a lot easier than it may look! It starts with making my easy Banana Bread batter. If you are out of baking soda, try Banana Bread (without baking soda).
Don't have brown bananas? Use this simple method of ripening your bananas using your oven for a quick turn around. After the batter is all mixed, divide it in half by scooping half the batter into a clean bowl, leaving the remaining half in the mixing bowl.
Next, add ¼ cup unsweetened cocoa powder to one of the batters. Fold in using a spatula or wooden spoon until well combined and no dry spots appear.
Scoop out about ¼ cup of the plain banana bread batter and place in the bottom of the prepared loaf pan. Then scoop the same amount of the chocolate batter and place next to the plain batter dollop. Continue alternating the dollops of batter, layering them on top of one another until you have used up all the batter.
Using a butter knife, swirl the batters together gently. Sprinkle the top with chocolate chips then bake .
Tips for Making Marbled Chocolate Banana Bread
- To mash the bananas, simply place the peeled bananas in a bowl and mash with a fork. No fancy potato masher or other equipment needed. I like to leave some pieces of banana in there – feel free to mash to whatever consistency suits you best! I typically need about 3 to 4 medium to large bananas for the amount specified in the recipe
- I use an 8×4 loaf pan, whereas I’ve seen many other recipes call for 9×5. This isn’t the hugest of deals, but my personal preference is to have a taller loaf of banana bread rather than a shorter, denser loaf. Feel free to use whichever size you have on hand
- When swirling the chocolate and plain banana bread batters together, resist temptation to keep swirling. Swirl only once through top to bottom of the pan. If you swirl too much the batters will blend together and you'll lose the marbling effect
- Don't like bananas? Try my Moist Vanilla Chocolate Marble Pound Cake (Loaf) instead.

Delicious recipe! I used half the sugar and it was plenty sweet. It's so moist and the chocolate makes it a more special banana bread. Thanks for the recipe!
Kim
That's good to know that you can cut back on the sugar and it's still plenty sweet - so helpful, thank you for leaving a comment and for baking it!

How wonderful Amalia!! Those swirls certainly are dreamy 🙂
Rachael
Hi, I made this last week and it was delicious! For kiddos lunch, I’m wondering about swapping some or all of the ap flour for whole wheat, any recommendations?
Kimberlee Ho
I would recommend swapping 1/2 cup of the AP flour for whole wheat. I haven't tested it with all whole wheat flour, so I'm not sure how it would come out.
Margaret
Omg just omg! This is the best banana loaf ever! Made it today! Def a keeper! 5 stars!
Kim
Woo hoo!! Such great news! Thanks for baking and leaving a comment, Margaret ❤️
Jeanne
I made this recipe semi-low carb… Half granulated Stevia sweetener and half sugar; half all purpose flour and half almond/coconut flour blend… It was super delicious my husband loved it. With Ghirardelli cocoa powder, absolute best! So much better and tastier than plain banana bread!
Kim
I love how you made this to fit your lifestyle! So happy you love it as much as I do.
Jeanne
Forgot to rate the recipe …I absolutely do rate this 5 BIG stars!
Kim
How fantastic!!

Could I substitute sour cream for vanilla yoghurt or mayonnaise?
Kimberlee Ho
You can certainly substitute the sour cream for plain full-fat yogurt or Greek yogurt. I would be cautious about substituting for a flavored yogurt, as these tend to have lots of sugar in them, which can alter the taste of the final baked product. I haven't tried mayonnaise as a substitute for sour cream, however, mayo contains eggs and may alter the flavor and texture of the finished baked good. If you try it, though, please let me know!
Earlyne
Hey kiss ass baker! This cake/loaf was the most delicious recipe I’ve ever made! My husband and I loved it! I didn’t have enough bananas so I added pure pumpkin to make up the difference. I also used half pretend sugar and granulated sugar. I would give you 10 stars!!
Kimberlee Ho
Wow that's fantastic!! Thanks for baking and for sharing your feedback!
Christine Derby
I happened on this recipe when I was looking for something to make with my very ripe bananas. Oh my….so delicious. I just made it for the 2nd time in 2 weeks because my family loved it. Thanks so much for the delicious recipe.
Kimberlee Ho
How wonderful Christine! So happy you stumbled upon the recipe!
Stephanie
I don’t have much granulated sugar. Can I use half granulated, half light brown?
Kimberlee Ho
Yes you can try that! The brown sugar has more moisture than granulated sugar, so it may make the cake a bit heavier and super moist. I'm interested to hear how this turns out for you!
Stephanie
Hi Kimberlee. I made the cake using both brown sugar and white. It wasn't an even half of each...I used a bit more of the white than the light brown sugar. The cake turned out moist and extremely delicious. My family loved it! Thank you for the great recipe! I'll definitely make this again.
Kimberlee Ho
So good to know this modification worked so well! That will definitely help other bakers. Thanks, Stephanie!
Christine Parkinson
I can see chocolate chips in the picture of the finished product but they are not listed in the ingredients list. When do they go on and are they in the bread too?
Kimberlee Ho
They are certainly optional! Add in 1/2 - 3/4 cup once the batter is mixed up, just before pouring it into the prepared pan.
Rubina Naeem
Can I use coconut oil instead of butter?
Kimberlee Ho
I haven't tried making the recipe with coconut oil instead of butter, so I can't say for sure.
Josie Dagostino
Can you use salted butter and eliminate the kosher salt?
Kimberlee Ho
Absolutely!
Rochelle
Absolutely loved this bread!! I'm not a fan of overly moist banana bread, so these are perfect!! the marbeling was easy to do. Had to search through my browser history to find this recipe to make again!
Kimberlee Ho
Wonderful! So glad to hear you loved it so much!
Chaitali
Can I use olive oil instead of butter?
Kimberlee Ho
I would not recommend using olive oil. The flavor is strong and will impact the flavor of the baked banana bread. Instead try using vegetable oil, canola oil, or avocado oil, as these do not have a flavor.
