Sourdough Banana Muffins are simple to pull together, using sourdough discard from your sourdough bread starter! Whip these lofty muffins up in about 15 minutes (hands on time) using a bowl and spoon, no mixer needed. They feature all purpose or whole wheat white flour, brown sugar, walnuts, and a hint of vanilla. Like in my Everyday Sourdough Banana Bread, sourdough discard creates the most flavorful, and tender baked recipes!

Highlights of Sourdough Discard Muffins
After creating this reader favorite Moist Banana Bread Recipe, I wanted to add another banana bread recipe to the Vanilla And Bean collection, sourdough style! And, when there’s sourdough discard in the house, Sourdough Discard Recipes are on the agenda. That’s where these irresistible muffins come in!
Tender. Fluffy. The magic is in the discard! Save it after feeding your sourdough starter, then hold on to the discard and repurpose it. Sourdough starter discard is delicious in baked goods! Let’s make the most of it.
If you’ve made these Moist Sourdough Pumpkin Muffins or my Lemon Bluberry Sourdough Muffins, you know you won’t find dry muffins around here! Moist and tender, these banana muffins aren’t very sour, as the sourdough flavor is subtle. But, the magic can be found in their tender and fluffy texture.

How to Make Sourdough Starter Banana Muffins
step by step
About Key Ingredients
Most of the ingredients are pantry staples, but here are a few that stand out.
- Brown Sugar: to make these muffins so fluffy, I employ dark brown sugar, however, you can use dark or light brown sugar. There’s not too much difference in texture, but dark brown sugar offers a bit more molasses, caramel flavor, and richness, and renders a slightly darker muffins. I find that the rise is a bit more even and lofty with dark brown sugar. But the difference is subtle.
- Melted Coconut Oil: tenderizes the muffins. You can use refined or unrefined. Unrefined carries the coconut flavor while refined is more neutral in flavor. I use unrefined. You can substitute canola oil if desired.
Resting the batter helps hydrate the flour and supports a lofty muffin. It’s worth the wait!
Knowing the temperature of your oven is key for best baking outcome. Use an external oven thermometer (dial or digital) to know its true temperature and adjust as needed.
Traci’s Tips for Fluffy Muffins
Muffin Pans: if you have two muffin pans, use them, alternating muffin cups so that every other cup is empty. This helps all the muffins rise more evenly, with a domed top. Baked in one pan, the center muffins don’t have quite as high of a dome as the outer muffins.
Muffin Cups: this recipe creates extra tall sourdough muffins so tulip muffin liners give them the support they need. Tulip cups can be purchased or follow the Kitchen’s DIY method for homemade!
Note the Temperature Change: we’re preheating the oven at relatively high temperature, but as soon as the muffins are popped in the oven, the temperature is lowered slightly.
Why? I tested this recipe at a starting temperature of 375F and then also at 400F, and found the high starting temperature helps give these muffins their loft and a nice domed shape. It allows the oven to recover to the baking temperature of 375F quickly even after the oven door is opened to put the muffins in the oven.
Fluffy Sourdough Banana Muffins
Ingredients
- 1 C (80g) Walnuts, whole
- 1 1/2 C (215g) Whole Wheat White Flour, or Unbleached All Purpose Flour
- 1/2 tsp Fine Sea Salt
- 1 tsp Baking Soda
- 1/4 tsp Baking Powder
- 1/2 tsp Cinnamon, ground
- 3/4 C (155g) Dark Brown Sugar, packed or sub light brown sugar*
- 2/3 C (135g) Coconut Oil, melted, warm to the touch or use canola oil
- 2 Large Eggs
- 2 tsp Vanilla Extract
- 1 1/4 C (305g) Mashed Bananas, about 3 very ripe bananas
- 1/2 C (160g) Sourdough Discard, 100% hydration, stirred down
Instructions
- Preheat the oven to 400F (205C) and set oven rack in the center. Line a standard muffin pan with 12 tulip style muffin cups or DIY your own. Tip: if you have two muffin pans, use both, leaving every other cup empty. This helps all the muffins rise to their full potential and helps create a nice dome.
Toast the Walnuts:
- Place the walnuts in a pan and set them on the center rack in your just turned on pre-heating oven. They'll toast for 15-18 minutes while the oven is heating (keep an eye on the walnuts since they're especially sensitive to heat and because ovens vary in how fast they pre-heat). Transfer toasted walnuts to a board and rough chop once cooled. Set aside a few tablespoons for sprinkling on top if desired. Chop fine. Set aside.
Make the Batter:
- In a medium mixing bowl, add the flour, salt, baking soda, baking powder, and cinnamon. Whisk the ingredients. Set aside.
- In a large mixing bowl, add the sugar, warm coconut oil, eggs, bananas, and vanilla extract. Whisk until the ingredients come together. Add the sourdough discard and whisk again until no white streaks remain.
- To the wet ingredients, add the dry ingredients all at once. Using a silicone spatula, fold in the dry ingredients and mix until no dry flour patches remain. Fold in the chopped walnuts, holding out the small portion for sprinkling on top. .
- Set batter aside to rest at room temperature for 15 minutes.
- Scoop an overfilled large cookie scoop (#20) or about 1/4 C each with batter and transfer to the muffin liners. Distribute leftover batter evenly among cups. Sprinkle with remaining walnuts if desired.
- Reduce the oven temperature to 375F (190C). Place the muffins in the oven and bake for 25-30 minutes. Use a toothpick to test several muffins starting at 25 minutes. Once the toothpick comes out clean with a few crumbs attached, the muffins are ready.
- Transfer the muffins to a cooling rack and cool completely. Once cool, cover for up to four days at room temperature. To Freeze: allow muffins to cool completely. Place individual muffins on a parchment lined sheet pan and freeze. Once frozen, transfer to a lidded container for up to two weeks. Thaw at room temperature.To Rewarm: rewarm muffins in a 350F oven for 10-15 minutes.

This was my first time using a discard for a recipe, as I have just begun my sourdough journey, and the muffins are delicious! I did cut back on the sugar to just under 1/2 cup and they are plenty sweet and I threw in a handful of mini chocolate chips! Will definitely make these again!
Perfect muffins! Seriously good, thank you so much.
So good. I subbed flax eggs for hens eggs and they came out perfect. Soft and so tasty. Thanks for this 🙏
Hi Nicola! Thank you for your note, sharing your flax egg tip and five star rating!
Wow! So light and fluffy and oh so yummy!
I did a gluten free version of this recipe.
I blended up some oatmeal to make 3/4 oat flour and 3/4 gf all purpose.
I used a hybrid 4TBS of unsalted butter and the rest coconut oil because the butter was left over from a recipe the day before.
I did 1 TSP of cinnamon because I love it!
I also used a little over half a cup of coconut palm sugar not packed and the sweetness is perfect!
I added 2 TBS chia seeds
I ended up separating the batter to make half nut friendly for school.
The nut friendly I added raisins and topped with banana slices
The ones with nuts I added sliced banana to the top of them.
You really can’t go wrong with this recipe!
Don’t forgot to watch the toasting walnuts or you will burn them like I did (my 2nd batch toasted up in less than 10min) and I forgot to turn the oven down when putting them in the oven-so glad I caught them before they burned! other than that the only thing wrong with it is the muffins won’t last very long! :)
Thank you, from a first-time follower.
GREAT RECIPE!!!light and moist muffin. Substituted truvia for sugar to make them diabetic friendly.
Delicious!! I was out of walnuts and burned all the pecans so I added a few dark chocolate chips…amazing! Huge hit with the family.
Yayyya! Oh nooo on the pecans… but what a delicious remedy with chocolate chips! Thank you for your note and giving the muffins a go, Cole! Day made!
Tried this recipe out this morning as I was looking to incorporate my sourdough discard in a recipe and it is definitely a winner, not too sweet and super delicious. My Grandson said no thanks Nanna I don’t like Banana Muffins but I insisted he taste it and the whole lot was devoured..
This is a winner. The recipe gave me 12 medium sized muffins.
Best news ever, Laura! I LOL at your Grandson. Thank you for your note and giving the muffins a go!
I love these. I made them vegan with 2 flax eggs, used only 1/2 cup coconut oil and 1/2 cup sugar and added chocolate chips. Great recipe. Thank you.
Hi Erin! SO happy to hear you’re enjoying the muffins. Thank you for your five star rating and sharing your tips with us!
Made this morning and they were so tender and delicious. I used 100% whole grain pastry flour, weighed my ingredients and they came out perfect! I cut back a bit on the brown sugar but then sprinkled some raw sugar on top before baking. Loved the bit of crunch on top. Baked in my Air fryer convection oven and it took 20 min.
Hi Carol! Hooray for tasty muffins! Thank you for sharing your tips and five star rating! Day made!
These didn’t work for me. Muffins were dry and the toasted walnuts were over. Felt like my oven was too hot.
I may try again at a lower temp/ shorter time.
Hi Danny! I’m sorry these didn’t work for you. I hope you give em a go again, but with an oven thermometer so oven temperature adjustment can be made.
