What You’ll Need:

This Sourdough Discard Banana Muffins keeps the ingredient list totally approachable—because good food shouldn’t be complicated. Here’s what you’ll grab at any regular grocery store to make about a dozen muffins:
- 1 cup sourdough starter discard (unfed, room temp)
- 3 ripe bananas, mashed (the riper, the better!)
- 1/3 cup melted butter (swap with coconut oil for dairy-free)
- 3/4 cup sugar (brown sugar adds great depth; white sugar works fine too)
- 1 large egg (can sub 1/4 cup applesauce for egg-free)
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 1/2 cups all-purpose flour (or swap half for whole wheat for a nuttier twist)
- 1/2 cup chopped walnuts or chocolate chips (optional, but highly recommended!)
Bonus kitchen nugget: I always add a little extra cinnamon or nutmeg for warmth—it plays so well with both bananas and sourdough tang.
This Sourdough Discard Banana Muffins is kind to your wallet because it uses ingredients that you likely already have on hand—banana muffins are a classic after all. Leftovers? Just pop them in an airtight container, and they’ll stay moist for a few days; freeze extras wrapped in foil for longer stash security.
Let’s Cook This Together:
Time to get these Sourdough Discard Banana Muffins bubbling with that irresistible aroma of bananas and sourdough.
- Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or lightly grease it. This step sets us up for easy cleanup and perfect muffin bottoms.
- In a medium bowl, combine your mashed bananas, sourdough starter discard, melted butter, sugar, egg, and vanilla extract. Give it a good stir until the mix looks velvety smooth. The sourdough discard brings this lovely rustic texture that’s part of the charm.
- In a separate bowl, whisk together flour, baking soda, salt, and any spices you want. This dry mix is your muffin’s foundation.
- Slowly add the dry ingredients to the wet, folding gently. The trick here is to mix until just combined—you want those Sourdough Discard Banana Muffins to stay tender and not tough. If your batter looks a bit lumpy, don’t sweat it—that means you’re doing it right!
- Fold in your optional add-ins like walnuts or chocolate chips. Both add a satisfying bite that elevates this banana muffin recipe with sourdough.
- Divide the batter evenly into your muffin tin. I like using a cookie scoop for even sizing. This step makes sure your muffins bake evenly and look ready for Instagram.
- Slide them into the oven and bake for around 20-25 minutes. Keep an eye on them after the 20-minute mark; you want a toothpick to come out with just a few crumbs, not wet batter. The kitchen will soon smell incredible when these Sourdough Discard Banana Muffins are almost done!
- Let them cool for about 10 minutes in the pan before transferring to a wire rack. Patience here means perfectly moist, not soggy muffins.
Tips I’ve learned through many kitchen trials: If your batter feels too runny, throw in a tablespoon more flour; too thick? A splash of milk or extra banana helps. While these muffins are best fresh, they freeze beautifully—grab a warm one with butter for a quick snack that never disappoints.
Quick shortcut: If you’re short on time, you can mix everything right in one bowl; trust me, these Sourdough Discard Banana Muffins forgive a little mess.
How to Serve & Savor It:

This Sourdough Discard Banana Muffins truly shines when you serve it with a slather of butter or a drizzle of honey for breakfast or a snack. Coffee lovers, this is your dream pairing—those cozy flavors match perfectly with a strong cup.
I often bring these muffins to brunches or potlucks because they’re a serious crowd-pleaser. Serve alongside a fresh fruit salad or creamy yogurt for a balanced spread. And if you want a little seasonal upgrade, try adding some caramelized baked banana slices on the side; they complement the flavors brilliantly. Here’s a fun twist I tried this winter: sprinkle a bit of cinnamon sugar on top before baking—hello, autumn vibes!
Leftovers? Don’t stop at muffins. Crumble some over your morning oatmeal or stir into a yogurt parfait. I even toss leftover muffin bits into a quick bread pudding for easy banana magic. When friends ask for something with banana muffin baking but a change-up, I point them toward this strawberry banana pudding dream recipe I adore—it’s just as comforting, just a different kind of joy!
These Sourdough Discard Banana Muffins have become a beloved treat in my circle. The blend of sweetness, wholesome sourdough, and tender crumb keeps people coming back for more.
Your Questions, Answered:
Can I prep parts of this Sourdough Discard Banana Muffins ahead?
Absolutely! You can mash bananas and mix wet ingredients the night before and keep them covered in the fridge. Mix dry ingredients fresh before baking for best rise.
What’s a good swap for butter in this banana muffin recipe with sourdough?
Coconut oil works like a charm, and for a lighter option, melted apple sauce can replace some butter, but you might lose a bit of richness.
How can I make this Sourdough Discard Banana Muffins for more or fewer people?
Simple math saves the day! The recipe scales up easily, just keep your ratios consistent. I love making double batches to freeze for later.
Can I make these gluten-free?
Yes! A gluten-free flour blend with xanthan gum usually works, but expect a slightly different texture. I’ve tested this with success by using one-to-one GF blends.
What if I don’t have ripe bananas yet?
No worries—slice and freeze bananas ahead. They’ll soften and sweeten while thawing and work perfectly in these muffins. I keep those frozen just for banana muffin baking moments.
Why use sourdough starter discard? Does it affect flavor?
Using sourdough starter discard adds a subtle tang and moisture, making these Sourdough Discard Banana Muffins uniquely delicious. It’s also a great way to reduce waste and get more bang for your starter buck!
Any fun mix-in ideas?
Try chocolate chips like in this banana chocolate chip sourdough muffins version I love, or nuts and dried fruits for texture. Pecans and cranberries are a fall fave of mine. For something decadent, a swirl of peanut butter adds richness.

My Top Sourdough Discard Banana Muffins Tips:

2. Don’t overmix your batter; that tender crumb is worth the patience.
3. Add some mix-ins! Whether nuts, chocolate chips, or a sprinkle of spices, little tweaks keep this recipe fresh.
Three tasty variations I adore: adding chocolate chips for that extra sweet hit, swapping walnuts for pecans, or folding in shredded coconut for a tropical note. The most requested? Definitely the version with walnuts and chocolate chips—always a winner.
