These healthy sourdough banana bread muffins are the perfect way to use up sourdough discard. They’re packed with good for you ingredients like oats, Greek yogurt and chia seeds.

If you’re like me an you’re always looking for ways to use up sourdough starter discard, these sourdough banana bread muffins are the perfect thing to make. They’re not only packed with sourdough starter, but they have a ton of good for you ingredients like oats, almond flour, Greek yogurt, chia seeds and banana.
When I eat muffins, I normally eat them for breakfast or as part of a snack. When I was looking for a great banana bread or muffin recipe to use up starter, I couldn’t find anything that had BOTH healthy ingredients and sourdough starter. So, to the drawing board I went.

To me, eating well means eating as much nutrient-dense food as possible. I’m lucky that I don’t have any food intolerances or allergies, so I eat all of the things…just in moderation.
How do you use up sourdough discard in muffins?

Using sourdough discard in muffins is actually incredibly easy. When you discard some sourdough, instead of throwing it away, pour it into muffin batter.
It’s great because you don’t have to wait for it to activate to make the bread rise, in this recipe there are leavening agents in the recipe. So really, you just mix it in like any other ingredient.

Are sourdough banana bread muffins easy to make?
SO easy. Like I said, you just mix the starter in with the rest of the batter. The best part – you only need one bowl!

In addition to how easy they are, they’re also crazy delicious. I like to add in chocolate chips or blueberries, but that’s totally up to you. I’m sure strawberries, blackberries or raspberries would also be yummy!

When you’re finished baking, you can eat them within a few days, or I like to freeze them and then heat them up for busy mornings, or to add to a special weekend breakfast in a flash. If you’re anything like us, you may want to double the recipe so you have enough!

Loved this recipe!!!
Thank you so much for sharing.
★★★★
I’m SOO glad! <3
Can I sub applesauce for the Greek yogurt to make it dairy free?
They are lovely, but I decreased the amount of sugar to 1/3 cup, it made only 12 muffins for me, and they required a good 33 minutes!
★★★★
Glad you enjoyed them but when you change the recipe at all, it can alter the yield. Filling the muffin tins more results in less muffins and more cook time.
I replaced the butter with coconut oil and these are SO good! Next time I’m going to try to use pumpkin instead of banana. Thanks for the great recipe! I look forward to more.
★★★★★
oh YUM! Let me know how the pumpkin turns out!
I made a toddler friendly version so replaced the coconut sugar with 1 tbsp of maple syrup. I couldn’t resist and had to try one – so scrumptious, soft, flavoursome and wonderful texture even with the reduced sugar. Thanks for sharing this recipe, I’ve bookmarked it so will definitely be making more!
★★★★★
Thank you. I was lokking for a sub to the coconut sugar
This is fantastic! We use blueberries. So flavorful and healthy. Thank you so much. A family favorite!
★★★★★
I’m so so glad!!!
These are yummy! I had frozen bananas so thawed then mashed to make 1cup. Omitted yogurt as I felt bananas were a little watery. Used coconut oil for butter. The oatmeal is a different twist-adds a little chew to muffin. I’ll definitely be making these again.
I’m so glad you enjoyed them!!!
I want to make these but do not have any almond flour. Can I substitute whole wheat or spelt flour? It seems like it should be fine, but I’m not sure if I should reduce the amount or add some more liquid. Thanks!
These were excellent! I’ve been looking for ways to use up my sourdough starter without regular flour and without a long ferment. I had to make some substitutions for dietary reasons- applesauce instead of yogurt, coconut oil instead of butter, cut the sugar to ~ 1/2 c, and used GF flour (Bob’s Red Mill 1 to 1). I did some with blueberries, some with chocolate chips, and left some plain. They were all great but the chocolate chip ones were my (and the kids’) favorite! Thank you!

I love this recipe. I have made these at least 6 or 7 times since I started making sourdough bread last year in May 2020.
I change it up a lot, using walnuts and/or blueberries or almond slivers.
I’ve also added chopped apple.
I usually use 3 very ripe bananas.
I’m making another batch tomorrow morning!
I usually give 1/2 away to my friends and neighbors.
I do the same with my sourdough bread, as most times I bake 2 loaves at once.
My neighbors and friends look forward to getting some goodies from the Neighborhood baker!
Thanks for this great recipe.
And, I really feel it a healthy muffin!
i substituted coconut flour for almond flour, reduced in half and added blueberries and chopped trader joes dark chocolate almonds. Oh also I used light brown sugar instead of coconut sugar – they were amazing, loved that I can use leftover bananas and my sourghdough starter!
I’m so glad to know coconut flour worked for you! Thanks for trying 🙂
Everyone I feed these muffins to love them. I do a long ferment by mixing it all together (except the bi carb soda and baking powder) and leaving it on the bench all day (about 10 hours). I mix in the bi carb soda and leave it to do it bubbling thing while I prep the muffin tins then cook it as instructed. I find it doesn’t need the baking powder because of the longer ferment. So good. Guilt free muffins.

Yum! Sounds so amazing, Julie. Glad you’re loving this recipe and so is everyone you share it with. Thanks so much for sharing your version, I appreciate it 🙂
