Your family will love the yummy pops of blueberries with banana bread. This is such a great combination of ingredients.

Sourdough Banana Bread Recipe:

This is a simple banana bread recipe. Especially if you have recently fed your starter and are looking to use up some over ripe bananas. That’s exactly why I made this bread.

I remembered how much we loved Kaytis’ recipe for Banana bread with blueberries. Blueberries and bananas are a great flavor team.

You are just going to LOVE how those pops of blueberry change the whole concept of banana bread. The sourdough adds its own deeper level of flavor. It’s pretty amazing.

ingredients for sourdough banana bread
All the ingredients are pictured except the blueberries.
  • We used frozen blueberries I had and needed to use. Fresh blueberries will also work great in this recipe.
  • All purpose flour
  • melted coconut oil. This is one of my favorite choices for baking quick breads. The coconut flavor is really a great addition in my opinion.
  • egg and vanilla
  • granulated white sugar (use organic if you prefer)
  • baking powder, baking soda and salt.
  • Sourdough starter (fed within the last week but the bread will rise higher if the starter is freshly fed and active)
  • very ripe bananas. The flavor of the bread will be impacted by the ripeness of the bananas.

If you use black skinned bananas with transparent and mushy parts the bread will have a quite strong banana flavor. Less ripe bananas means less banana flavor.

Our banana bread recipe is moist and full of full banana flavor with bursts of delicious blueberries hidden inside. It’s an easy to recipe to make and yields a perfect loaf or muffins for a party.

We chose ripe bananas that were still yellow skinned and love the flavor for this recipe.

Additions, variations and Substitutions:

  • Add 1 Cup chopped walnuts for a crunchier texture
  • Chocolate chips make a very good banana bread variation and can be substituted for the blueberries.
  • Feel free to change the oil to avocado oil or other oil if you prefer. Just do NOT use a really strongly flavored oil like olive oil. The flavor of the oil should disappear or compliment the bread.

Hi Diane, I am new to baking. My wife’s friend makes the beginners artisan sourdough bread. She gave me some starter and I had success with it. I decided to try this blueberry bread. I had six ripe bananas so I doubled the ingredients for two loaves. I have two questions. When you double the recipe, do you double the baking time? Also, how do you store the banana bread? I bought linen breathable bags for sourdough, or would it be better to wrap it in Saran?

Thanks for your help.


Friday 1st of January 2021

Hi Craig, Welcome to Homemade Food Junkie. If you double this recipe please make it into TWO pan loaves rather than one Ginormous boule. If you attempt to make this recipe a large boule I don't expect it to turn out well at all.

This is actually a quick bread recipe with added sourdough starter discard. It is Nothing like an actual sourdough bread like our Artisan loaf your wife makes. You can store this bread in any ole plastic grocery sac to keep it fresh a few days sitting out. For freezing wrap it tightly in the plastic wrap and cover completely with foil.

I have never tried breathable bags for sourdough. Sound intriguing. However this bread should not need fancy wrapping. It rarely lasts on the counter for more than a day at our house.

This is a simple quick bread recipe that is using the discard starter to enhance and deepen the flavors. Please let us know if you have further questions. Happy New Year and Happy Baking!

Thank you for this recipe. I love it! It is moist and the sweetness is just right for me. I baked it today with an active starter. Made two loaves that yielded 14 slices each loaf. I will make this over and over again. My friend loved it too.

Hi Mercy, We SO appreciate your great feedback and review of this recipe. I'm so happy you enjoyed it. Happy Baking!

My husband and I ate the whole loaf in one day. So what does that say about this recipe. Used 1/2 whole wheat flour and 1/2 brown sugar. The photo above recipe says “24 servings 2 loaves” but it only made 1 loaf.


Friday 10th of July 2020

Hi Alison, Oops! I will revise the recipe for the one loaf. Thanks for mentioning that. I'm so happy you enjoy it.

This is so good! I just started a sourdough starter and it morphed into three different ones so I have a rather large jar of discard in my fridge. I mix all my discards so there was bread, wheat and rye flour in one . I love making banana bread to share with friends and family. I didn't have coconut oil so I substituted with butter and my frozen blueberries never would have mixed properly so I put half the batter in the pan , put the berries in a layer then added the other half batter. Perfection! Will definitely make again.
