Light and fluffy sourdough banana bread is a simple and classic quick-bread. Overripe bananas are combined with sourdough starter, brown sugar, flour, and a few other ingredients to make the most delicious and moist banana bread.
This is one of those classic foods that we frequently enjoy. A rustic dessert, snack, or even breakfast.
The humble sourdough banana bread is delicious and packed full of banana flavor, yet easy enough to whip up in the afternoon.
Recently, I had Sara Jo from Bryarton Farms on my podcast to discuss all things farmhouse.
From architecture, to finding your own dream farm on a budget, she was so much fun to chat with. Our conversation even led to the misconception of farm life being dependent on large incomes.
If it is something you really desire, you can totally make it happen. And while you are patiently waiting for your dream farm, or even just a few acres right outside of town, there is no better opportunity than right now to get started on developing your skills.
Learning to cook and bake from scratch, ferment foods, the art of preserving, sourdough baking, even getting a few backyard chickens.
There is no day like today to start.
So, let’s make this yummy recipe that can easily be made into a quick-bread, or long fermented for 12-24 hours to get the most benefits from the fermented grains.
Tips:
- If you absolutely don’t have overripe bananas but have a real craving for banana bread, you can speed up the process. Place unpeeled bananas on a baking sheet and bake for about 30 minutes in a 250 degree oven. They will be brown on the outside when they are done.
- Don’t over-mix the batter. Over-mixing the dry ingredients into the wet ingredients causes gluten formation, which can give you tough banana bread.
- You can also make this recipe as muffins. Make the recipe the same, and place the batter into regular sized muffin tins; bake for 20-25 minutes until they start to turn golden brown and a toothpick comes out clean.
- If you like more banana texture, reserve a little bit of banana during mashing and mash it more gently to add more of a chunky banana bite.
Why you will love this recipe:
It comes together quickly: It’s a quick bread and comes together in less than 10 minutes. Perfect for coffee with friends or a special breakfast. Or start it the night before and it’s even faster the morning of.
Packed full of flavor: Not only is this recipe packed full of banana-y goodness, but if you ferment the dough it will also have a delicious and slight tangy sourdough flavor.
Fermented grains: If you choose to ferment your grains before baking, this means the nutrients in the grain are more bio-available (aka your body can absorb them better). Thus making it a little bit healthier.
Super Moist: This isn’t a dry loaf – not even close. The banana adds the perfect moisture to this recipe.
FAQ
What do you eat banana bread with?
Typically, if we’re enjoying banana bread as a snack or dessert, I just serve this warm with a little butter.
If it’s breakfast, I may serve it with a side of eggs and fruit.
You could make it into a delicious French toast. Use this recipe, but swap out the cinnamon raisin bread and don’t soak the banana bread in the egg mixture long.
How ripe should bananas be for banana bread?
The riper the better. They should be mostly brown, soft, and with very little yellow on the peel.
Sometimes, it is hard to predict or plan when a banana will be the perfect ripeness for bread. So, if you find yourself with very ripe bananas but no time to actually make the bread, just place them into the freezer and pull them out a few hours before baking.
Is sourdough the healthiest bread?
It is definitely one of the healthiest bread options out there. Not only does it contain more vitamins and minerals compared to “regular” breads, but it also contains less phytic acid which binds the minerals up, making it difficult for the body to absorb. More nutrients + better absorbability = healthier and delicious.
Can I freeze overripe bananas?
Yes. There are two ways to freeze bananas. Freeze unpeeled bananas for up to 3 months. Place in an air-tight container. Or peel and chop up bananas and place in a zip-lock bag.
Doesn’t just about everyone have a few bananas in their freezer?
Why is my sourdough banana bread lumpy?
If you are long fermenting your banana bread, it is very common to have clumps of sourdough dough that don’t get dispersed evenly. You could mix it slightly longer, but it is quite normal to not be able to mix in every single lump due to the fermented dough being quite thick. It’s not something I worry too much about, and your bread will still be delicious.

Sourdough Banana Bread Ingredients
- Ripe bananas – the riper the better. As bananas ripen, they become sweeter and the flavor more intense.
- Eggs
- Sourdough starter – This can be active sourdough starter or discard.
- Vanilla extract
- Butter – unsalted.
- Dark brown sugar – Dark brown sugar adds a stronger molasses flavor, giving it a more caramel-y flavor. If you only have light brown sugar, you can use it, but it will lack that extra yumminess.
- All Purpose flour– You could also substitute whole grain flour, for a heartier result.
- Baking soda
- Baking powder
- Salt – always add salt to desserts and baked goods. It really brings out the flavor and the sweetness of the dish.
Optional Add-Ins:
If you would like to add some extras to your banana bread, try one or two of these:
- Nuts – pecans or walnuts are our favorite
- Chocolate chips or chunks
- Blueberries – fresh or frozen
- Coconut flakes – about 1/2 cup
How To Make Sourdough Banana Bread:
Preheat oven to 350 degrees.
Lightly grease a 9×5 loaf pan with butter.
Combine dry ingredients (flour, baking soda, baking powder, and salt) well in a medium bowl.
In a stand mixer or bowl, mix melted butter and brown sugar for five minutes until light and fluffy.
Add in eggs, vanilla, mashed bananas, and sourdough starter.
Fold in dry ingredients a bit at a time until just incorporated. Be careful not to over-mix.
Gently fold in any other add-ins you would like (pecans, walnuts, and chocolate chips or chunks, etc.).
Pour into a greased pan. You could also line your loaf pan with parchment paper.
Bake for 50-60 minutes. Test bread at 50 minutes with a toothpick or cake tester.
Allow to cool in the pan for one hour.
Long Fermented Sourdough Banana Bread Directions:
12-24 hours before you plan to make banana bread, mix together sourdough starter, melted butter, eggs, and flour. Cover with a towel or plastic wrap and allow to ferment at room temperature for 6 hours. Put the batter in the fridge and allow it to ferment for another 6-18 hours.
The next day, preheat oven to 350 degrees.
Using a stand mixer with the paddle attachment, add brown sugar, vanilla, mashed bananas, salt, baking powder, and baking soda to mixing bowl.
I highly recommend using a stand mixer because the fermented dough will be stiff and difficult to combine with the other ingredients by hand.
Set on low to medium speed until completely combined.
Pour into loaf pan and bake for 50-60 minutes.
Allow to cool in the pan for one hour.
How To Store:
This will last at room temperature, in an airtight container (or in a ziplock bag), for 5 days.
You can also store it in the freezer (after it has completely cooled) for up to 6 months.

Hello! I have made this recipe 2 times and loved it both times. If you have time could you also include the ingredient measurements in grams? I just prefer to weigh my ingredients and most of your recipes include it. Thank you!
I have a conversion chart for those that like to convert them to grams!
Hi Lisa,
I am wondering if I could substitute honey or maple syrup for the brown sugar in this recipe.
Thank you,
Beth
Yes, you sure can!
Yay! Thanks
We love it!! I tried this recipe for the first time this weekend. I let it ferment for 12ish hours before mixing and baking – had me a little worried because the dough was not mixing with the other ingredients at first! But it just took some extra patience (and my electric hand mixer, I don’t have a stand mixer). I made just plain banana bread w/out toppings or extra add ins and it is delicious! The whole family loved it. 🙂
Hi Lisa! I made this recipe, followed the instructions exactly as written, and my bread came out completely raw on the inside. The outside was nice and golden brown, and when I put a toothpick in the middle and it came out clean.
As it cooled for an hour, the middle slowly began to sink in. I tipped it out of the pan and it all fell into itself since it was so raw in the middle.
I used a 9×5 loaf pan, but it was glass.
Do you have any ideas as to what I may have done wrong? It smelled amazing, and I’d love to try and make it again. But unfortunately this loaf couldn’t be salvaged 🙁
Hmm. I wouldn’t think that a glass loaf pan would make a difference. Do you normally have to adjust your oven temperature or times? You could always cover the loaf, so it doesn’t burn on the outside and can cook a little longer internally.
When I use my glass loaf pan, I check at 50 min. then just lay a piece of foil on top and bake 15-20 min more. It has turned out great for me. The foil prevents the top from over browning and the center cooks perfectly. This has not happened with my metal pans, they bake 55 min and are perfect.
Hi Lisa!! I’ve been watching you and making your recipes for years! Thank you for all you show us!!
I wanted to make your sourdough pumpkin muffins. Can I “long ferment” that recipe as well similar to how you have that option here?
Thanks!!
Yes! So glad you enjoy the content.
This banana bread was extremely delicious! My kids loved it, even my sister in law who is a picky eater and loves those sugary treats! So happy I’ve tried it! It’s a must!
Yay! That is wonderful to hear!
Can I make this with freshly ground soft white wheat since I’m not depending on the sourdough leavening? Or does that not work?
I haven’t tried that, but it should work. The final product may be more dense than it would with AP. Let us know how it turns out!
Hi Lisa!
Quick question, I’ve made this twice and I do the long ferment method. After mixing there are tiny balls of dough still in the batter, I mixed for quite a bit and trying not to overmix but im wondering if there is a solution for that? Maybe letting the dough come to room temp first?
Thank you for allll your recipes!
Love this recipe. I made muffins this morning and they were fabulous only thing missing were my favorite nuts (pecans). I am loving all your recipes. Thanks a million.
Sounds like a great addition! Glad you enjoyed them.
Lisa, so for the long fermenting do we add 1 cup of discard sourdough? I didn’t see this until after mixing 1/2 c of starter with the eggs, flour, and butter.
Hi Carol! Where are you seeing one cup? It should be a 1/2 cup for both versions.
Hi Lisa,
Back on November 10th, 2022 you commented on this post that you retested the recipe and that 1 cup of discard was needed for the long ferment so that it had enough moisture. I’d really like to try this recipe but there is some confusion. Is there a consensus on what is the best amount to add to the long fermented version? Thanks!
Is the cook time and oven temp accurate on this? I baked for 60 minutes and the middle was completely wet. I continued to bake in 5 minute increments for the next 30 minutes and the knife is still coming out wet. Ive made so many other recipes from Farmhouse that turned out great. I don’t know what I’m doing wrong…
Hmm .. this temp and time works for me and my oven, but every oven can be different. Without seeing it, I am not sure what the issue may be. Sorry you are having issues with it!
