Prep Time 10 mins
Cook Time 1 hr
Total Time 1 hr 10 mins
Servings 8 servings

Ingredients 

  • 2 cups all-purpose flour
  • 3/4 cup sugar
  • 3/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3 very ripe, darkly speckled large bananas, mashed well (about 1 ½ cups)
  • 1/4 cup buttermilk
  • 2 large eggs, beaten lightly
  • 6 Tablespoons butter, melted and cooled
  • 1 1/2 teaspoons vanilla extract
  • 2 medium zucchini

Instructions 

  • Preheat the oven to 350ºF.
  • Line a 9-inch loaf pan with parchment paper then grease the parchment paper with cooking spray.
  • In a large bowl, whisk together the flour, sugar, baking soda and salt.
  • In a separate medium bowl, whisk together the mashed bananas, buttermilk, eggs, melted butter and vanilla. Stir the banana mixture into the dry ingredients.
  • Shred the zucchini on a box grater. Measure out 1 ½ cups of shredded zucchini then squeeze is with your hands over the sink to remove excess liquid. Fold the zucchini into the batter then scrape the batter into the prepared loaf pan. Bake the bread for 50 to 60 minutes until a toothpick inserted comes out clean. Transfer the pan to a cooling rack to cool then lift the loaf out of the pan, slice and serve.

Kelly's Notes:

  • Squeezing the excess moisture out of the zucchini ensures your bread won’t sink in the center.
  • Extra-ripe bananas are the key to the most moist, flavorful banana bread. Don't be afraid to let bananas turn completely brown before using them for banana bread. If you don't have extra-ripe bananas, check out my video for how to ripen bananas in 15 minutes.
  • If you don't have buttermilk on hand, you can make a quick version using whole milk and lemon juice or white vinegar. Add 1 tablespoon of lemon juice or white vinegar to a liquid measuring cup, and then pour in the milk until it reaches the 1-cup mark. Let the mixture sit for 5 minutes, then use ¼ cup for this recipe and save the rest for another use.

    I wanted this to work! I squeeeeezed 1 1/2cups grated zucchini in a tea towel after reading some of the other comments. I was actually afraid I squeezed out too much moisture. After baking for 50minutes I cut into it- still undercooked- 10 more minutes- soggy I the middle-10 more minutes- still soggy but the rest is getting dried out.
    I used the tip on ripening my bananas in the oven and am wondering if this is the cause of my issue. Baking the bananas at 350° for 15 minutes made the bananas super soft and very “watery” and I believe the chemical change and breakdown of the fruit is what did this to the recipe. Maybe I’m wrong?

    1. So strange, Vanessa! I’ve never experienced that issue when using the banana ripening hack. Please feel free to email me so I can help troubleshoot.

  2. My grandsons and I followed the recipe to the letter. It baked for 60+ 10+ 10 minutes at 350 and another 20 minutes at 375 degrees. We had squeezed the heck out of the home-grown shredded zucchini. The middle never rose or baked at all. Only the outside was brown and crusty. I know I used the right amount of ingredients.
    What happened?

    1. This is so strange, Ellyn! I’ve never experienced that issue with this recipe before. Please feel free to email me so I can help troubleshoot.

  3. Tried this tonight for the first time. Doubled the recipe and used plain milk. Turned out fantastic! One loaf to the neighbours and one loaf almost devoured by my son after his soccer game – he actually walked into my bedroom saying this is REALLY good Mom…like fantastic. It’s 10:30 pm and I just doubled the recipe again and they’re baking in the oven! Hand squeezed the zucchini like the recipe said – pretty important. Give it a try.

    1. Hi Ginette – I don’t understand your question. Can you please clarify what you are asking?

    2. Ginette:
      Don’t pay any attention to the cup amount for the bananas; it does not change when you double or triple the recipe. Use the number of bananas.

    I made this bread today & its delicious – moist & lots of flavor. I made sure that the zucchini was well squeezed. I did 4 mini loaves and baked them just under 40 min. They are a little undercooked but that’s my oven & I’ll adjust accordingly the next time. Kelly, thanks for the ripening tip for bananas. I had 2 ready to go but they were small so I needed 2 more. The oven trick worked like a charm! I’ve saved this recipe in my files and I will definitely make it again as zucchini season is upon us!

    1. 5 stars!! So good!! Mine turned out perfect, other than just a thin layer on the bottom that is still pretty moist, but I think it may be because I probably didn’t do a very good job sqeezing the water out of the shredded zuccini. I will try it again, I have lots of zucchini in my garden. Not to mention it smells so good when baking!! It’s a new favorite at our house! Thanks for sharing this awesome and super easy recipe, Kelly!

    This was really delicious! I have such bad luck getting quick breads to cook in the center, and this was no different for me unfortunately. I’ve started baking them in square pans like cakes. I lifted it out after an hour and split it down the soggy middle, then laid the two halves out on a baking sheet to finish. An added bonus was the slightly crunchy edges and sides, which I love. Will definitely make again, in a cake pan.

    1. I almost always bake these type of breads in a Bundt pan. They cook through evenly and it takes less time generally. I have found that for banana bread recipes that call for 50 minutes in the oven, in a Bundt pan, the time could be as little as 35 and all will be cooked through evenly.

  6. 1 star
    I ended up cooking the bread for almost two hours and it was too wet still! The butter bubbled up and leaked into the oven so that was a smokey mess. I did thoroughly squeeze the zucchini, but I think there is just too much liquid in the recipe. Pretty bummed that I had to bin it.

    1. Hi Lianne! I’ve never experienced that issue with this recipe before. Please feel free to email me so I can help troubleshoot.

    Best, best. best Zucchini/Banana bread we have ever tasted. Loved the how to ripen banana tip. No oil used, that is a plus. I love the butter milk in the recipe. I added pumpkin pie dry spice instead of cinnamon. Came out so moist and fluffy. I put in fridge for about 2 hours to give it body, then spread cream cheese or soft butter on it. We didn’t use any nuts cause the grand kids don’t like them. They did not even know it had Zucchini. I am a hero in their eyes.

  8. I just made a loaf, I diced the zucchini (only used a cup after squeezing) then added 15 minutes longer cook time. Smells and looks great also cooked through.

  9. I have made this bread several times and came out great. I use the smaller loaf pans and can get 3-4 easily, esp if I add nuts to it. I’m about to make more and I’m glad I found you again. Super great….family and friends love it (even my picky eaters). Thankx again

    I simplified this recipe and reduced the calories by 1000 (not a typo). I put all dry ingredients in my stand mixer and all wet in Vitamix. Insted of 6T butter, I put an apple in the Vitamix and instead of sugar I used 1.5t Stevia drops. I think I used more than 1.5 c zucchini and even though I squeezed some liquid out, it looked too runny so I added another 1/2 c of flour (375g altogether). I used 1t lime juice to 1/4c milk and let it sit to sour before adding to vitamix. I whipped wet hard to liquify apple and bananas. I added 90g chopped nuts (cashews/peanuts – Costco packs) at end when stirring in zucc. This added back 530 calories but better than butter and sugar! Vegans can use flax or chia eggs.

    I made this bread recipe tonight and doubled the recipe. It filled three of my bread pans. I added chopped walnuts and used wheat flour for 1/3 of the white flour called for. It came out perfect!
    We love it! Thanks so much!

  12. I added some grated apple (tis the season) & cut back a bit on the banana & zucchini accordingly. Then baked in 3 mini loaf pans 30 min & they turned out fantastic!

  13. 4 stars
    I had the same issue as several others and I am a seasoned baker as well. I ended up adding an additional 25 minutes and the bottom was still a bit squishy. I thoroughly squeeze the zucchini, so I don’t think that was the issue.
    My toddler son has been eating it non-stop however, so it obviously tastes great!

    1. Hi Rachel – This is so strange! Did you measure out 1 1/2 cups of the shredded zucchini before thoroughly squeezing it?

  14. 5 stars
    Absolutely love! I’m always hesitant to use a different recipe than my “go to”
    But this did not disappoint! So moist and flavorful. Throw in a cup of chocolate chips to make it even better!

  15. I have learned that baking the “breads” = = all breads that seem to take forever to cook and never get done in the middle == do better being cooked in round pans like cake pans (2 in place of a loaf pan) or two 8 x 8 pans…….

    I don’t know if it’s the ovens that differ? but it seems to work for me…..

  16. 5 stars
    I wish I would’ve taken a picture before we cut into it! This is a great recipe. I did not have buttermilk, but I make my own almond creamer, just almonds and water, I substituted just that and it still came out fabulously!
    Now if you could only come up with a gluten-free recipe!

    1. Hi Patti! You could try using a gluten-free flour such as Cup4Cup that’s a 1:1 ratio as regular flour. I’ve never tried this substitution so I’m not sure what the result would be. Curious to hear your results if you give it a shot! :)

  17. Middle never cooked. I followed directions. I’m so disappointed. I was going to take it to pot luck tomorrow. I don’t get what I did wrong?

    1. Hi Karen – I’m sorry you didn’t have success with this recipe. Did you thoroughly squeeze out the zucchini?

  18. I agree with Angela. I am a seasoned baker. Breads are my speciality. And this did not bake through. I left it in for an hour and 20 minutes, and when I cut into it, it was really gross. I’ve used your recipes tons of times with no issue. Something is off. Maybe it needs more flour for that amount of banana and zucchini? Or maybe I should have split it into two pans. But it did not work. Back to my cousin’s zucchini bread recipe and the original Chaquita banana recipe I’ve been using for years.

    1. Hi Stephanie – I’m sorry you didn’t have success with this recipe. Did you measure out 1 1/2 cups of the shredded zucchini and did you thoroughly squeeze it out?

  19. 5 stars
    Made this yesterday. nice and moist. i used cinnamon and ginger instead of vanilla as my DH requested. very happy with the texture. oh, also added pecans. i really appreciated your breaking down of exactly how much zucchini to use. from my garden i pick all sizes of zucchini and was intimidated by “2 medium zucchinis”! but when i read the part about 1 1/2 cups i was relieved! i have saved this recipe.

  20. I don’t get what I did wrong. I rung out the zucchini and followed the directions but this cake would *not* cook through. I even divided it into two loaves and after more than two hours in the oven the toothpicks were still not coming out clean. (My oven is newer so it’s not that).

  21. How much grated zucchini do I need to use? I usually use the giant ones for bread.

    For the person whose bread takes forever to bake, I have found that is if make medium loaves instead of large it bakes more evenly and without getting too dark. I haven’t make this recipe yet but plan to tomorrow.

  22. I have tried this recipe twice now and it just doesnt cook.

    This last time I cooked it for 3.5 hours at 350 and the outside burnt but the. Inside is still raw. How disappointing. What could have gone wrong?

    1. Hi Melanie – I’m so sorry you had that experience. Do you have an oven thermometer to ensure your oven is running at the correct temperature?

  23. Hi Kelly,
    I can’t wait to try this recipe. It looks like you used the large holes on the box grater. Can I use the small holes? My husband is not fond of zucchini so I want to more or less sneak it in. Might it be too watery even after squeezing? Thank you! Sylvia

  24. I made this recipe this morning, it was very easy to make. I used vanilla almond milk instead of buttermilk. Came out delicious thanks for this recipe.

  25. Coconut, orange peel, coconut oil substitute, pecans, yogurt substitute. Was soooooo good. Made double. Cut coconut oil into dry ingredients then added. Then added red huckleberries from my yard and it looked like Christmas, tasted like Christmas

  26. 5 stars
    Super moist, perfectly sweet, all around delicious! The kids thought they were eating cupcakes for breakfast! lol

  27. This was delicious! I also added some cinnamon and nutmeg. Half white flour, half whole wheat. Half sugar, half honey. Instead of buttermilk I used almond milk and full fat yogurt. Half butter, half coconut oil. Topped with chocolate chips. Delicious! Thanks for such a strong base recipe to play with.

  28. 5 stars
    I made this and it was delicious—so flavorful and moist. The only one thing that I did differently was to add 1/2 tsp of cinnamon and 1/4 tsp of nutmeg because I like those flavors in my baked banana or zucchini breads. I also divided up the batter into 4 small loaf pans which was perfect as we could freeze some and eat Some right away!

  29. Am I able to make this using almond meal or any other gluten free flour? I have a friend who is gluten intolerant.

    1. Hi Karine! I haven’t tried this recipe with any other type of flour so I’m not sure. You could try using gluten-free flour such as Cup4Cup that’s a 1:1 ratio as regular flour. Let me know if you give it a shot!

  30. 5 stars
    Made this tonight with zucchini gifted from my neighbor .so delicious! Love the combination of banana and zucchini..I spread some soft cream cheese on for extra decadence
    Great recipe

  31. Hi Kelly
    Just tried it replacing egg with ground flax seeds and also ground dates and a pinch of cinnamon instead of sugar. Result YUMMY

  32. 5 stars
    Th bread turned out very moist and delicious. The only thing I didn’t add was the butter, but only because I forgot about it in the microwave. I panicked at first, but the bread didn’t even need it it. It’s very flavorful!

  33. 5 stars
    I just made these. I used 1/2 cup of sugar, cut out thè butter. I added an oatmeal topping. Moist and still sweet enough. I would add a photo by I don’t see that option.

    1. I’m so thrilled you enjoyed the recipe, Carrie! And if you happen to be on Instagram, you can share your culinary creations with me by using the hashtag #justatasterecipes :)

  34. Any suggestions on replacements for the 3/4 cup of sugar? Not honey or syrup.
    Love this recipe, but need to cut out sugars.

    1. Hi Lisa – I’ve never tried this recipe with a sugar substitute so unfortunately, I can’t weigh in on this!

  35. Hi Kelly
    Could I use this recipe in my class of 20, 5 year olds please? I will write it out and reference your name and the Just a Taste website. It will also be a bit different as I have a child allergic to eggs and use Chai seeds instead and I will reduce the amount of sugar used too and like you asked on your site I will write the method out differently too. I cook with my class every week and love finding new recipes that use vegetables and fruit. Thank you
    Jacqui Baker

    1. Hi Jacqui! Yes, you have our permission to use this recipe with credit to Just a Taste and this post. Thanks and have fun baking!

  36. per the comments about subbing out the buttermilk, what about with sour cream which is sometimes an ingredient in banana bread?

    1. Hi Greg! I haven’t tried this recipe using sour cream in place of the buttermilk, but my initial thought is that it should work. Would love to hear your results if you give it a shot!

    1. Hi Roberta – I’ve never tried making this recipe with a sugar substitute but the taste and texture will likely be altered if you do. Sorry I can’t be of more help!

  37. Hey there! I pregrate, drain and freeze my zucchini ahead of time, so I wish that I knew how many cups of grated zucc that is

  38. I added chopped walnuts to mine and am trying to bake it in my new Copper Chef pan that has been advertised on an informercial on tv. I didn’t add the parchment or butter. Just an experiment all the way around! Its still cooking but smells amazing.
    Keep you posted!

  39. We all loved it! A nice combination of veg & fruit. Baked it for almost 65 minutes; actually we doubled the recipe due to quantities of both so we’ve got one to freeze but the first loaf won’t last long. Used very ripe bananas and wrung out zucchini. So moist. If that’s the secret, it’s out now. Will definitely make again. Thank you.

  40. Hi Rupa – Per the recipe: “In a separate medium bowl, whisk together the mashed bananas, buttermilk, eggs, melted butter and vanilla. Stir the banana mixture into the dry ingredients.”

  41. Hi Kelly,

    I squeezed the zucchini with paper towel..the cake is dry on the top and uncooked in the middle…what did I do wrong?:-(

    1. Hi Malinee – I’m not certain what the issue could have been but if it’s uncooked/sunken in the center, the bread likely didn’t cook long enough.

  42. Hi Kelly, I have some overripe bananas stored in my freezer – is it possible to use those in the bread if I let them thaw out beforehand?

  43. Tried this tonight, love the flavor. My bread didn’t sink at all, but it was still quite soft and undercooked in the middle. I was careful to squeeze the zuchinni a great deal. Do you have any tips to get the most liquid out of the zuchinni?

    1. So glad you enjoyed it! You can put the zucchini in a dish towel to really ring out the moisture if you’re still having issues with the bread sinking.

  44. Hello,

    It would be a little more helpful if you could give a measurement of zucchini, rather than saying 2 medium. Is that possible?
    thank you

    1. Hi Lynda – Shredding and then squeezing out the zucchini leads to a wide range of quantities, so it’s more accurate to just use two medium zucchini (versus stating how many cups, etc.).

  45. I don’t know what’s wrong, mine still wet in the middle even i baked it for 1 hour. Only bottom and the top got cooked. :( it was unsuccessful….

    1. Hi Eden – The likely issue is that all of the liquid wasn’t squeezed out of the zucchini. Additional moisture would cause the bread to not cook through.

  46. Just made this ( my first ever making bread ) and I don’t know what I did wrong but it didn’t bake on the inside and it sunk. I followed the instructions exactly..I think. :( so bummed out because it looks and it smelled SO good.

    1. Hi Jess – Did you thoroughly squeeze out the zucchini? It would’ve likely sunk in the middle as a result of extra liquid.

    1. Hi Jude – If you don’t have buttermilk, you can make your own (per the notes in the recipe) with milk and lemon juice or vinegar.

  47. I would love to try this recipe, but my one question is what would I do with the extra 3/4 cup of the substitution for buttermilk if I don’t have any other recipes that call for buttermilk? I know…how about 1/4 of a tablespoon of the white vinegar or lemon juice and milk to make 1/4 cup? Then there would be no waste!

  48. Just got a nice chubby zucchini in this week’s CSA basket and have very ripe bananas in the freezer waiting or me to use, so guess what I’m making tomorrow? Can’t wait to taste this, it sounds so good. Thank you.

  49. I am surprised and love how the zucchini stayed so green! This bread is so pretty and dare I say- a health food? ;)

    1. Thanks so much, Gina! And yes, you could count this as a full (HEALTHY!) serving of fruits and veggies ;)

    1. Hi Dana – I’ve never tried substituting applesauce for sugar in this recipe so I can’t provide the exact proportions.

  50. Is the recipe still good without the sugar. I want to make it for my one year old, and I am still avoiding sugar in her diet.

    1. Hi Camilla – I’ve never tried making this recipe without the sugar but the taste and texture will be altered if you omit it.

      1. 2 stars
        The ingredients are great and I followed the recipe exactly. Like many others, the bread did not rise and bake all the way through, even after adding another 40 minutes. I am wondering if you forgot to put baking powder on the ingredients list? Every recipe for quick breads I see has baking powder with baking soda. I will try it again with the baking powder and I’m sure it will resolve the problem.

      2. Hi Heidi! This recipe does not require baking powder, only baking soda, which reacts with the buttermilk and causes the bread to rise.
