One-Bowl Sourdough Banana Muffins

If you’re looking for a great recipe to use up some of your sourdough discard, look no further! These vegan, sourdough banana muffins only need one bowl and a muffin pan to create a delicious snack.

Last year, I had quite a bit of sourdough discard stowed away in the back of my fridge, and while I have made biscuits, pancakes, and flatbread with it, I wanted to try something new! So, I found Lisa’s (the Viet Vegan) recipe for Sourdough Banana Bread, and made it a few times, and I think it’s a great foundation recipe.

Now, I like my bread a lil’ sweeter (but not too sweet!), and with a couple other additions, but still kept it nut-free to be more allergy-friendly, though you’re more than welcome to add some in! I’ve added a note in the Substitution + Tips area below, just for you. On top of the ingredient changes, I have made the recipe into muffins, which are great for sharing. Though I’ve made it as a loaf as well, in case you like that form better.

Substitutions + Tips

  • Very Ripe Bananas – if you want the best flavor, and most added sweetness, make sure that your bananas are VERY ripe. I mean brown peels. Typically, I let bananas ripen on the counter, and once they’re dark I pop them in the freezer for later.
  • Sourdough discard – the recipe works better if you let your discard get close to room temperature, if it has been in the fridge. Mine was fed with 1/2 whole wheat flour, so that changes the texture of the muffins slightly. This will vary from starter to starter!
  • Dark brown sugar – I find this lends more depth of flavor than light or cane sugar. If you don’t have it on hand you can use cane sugar and add 2-3 teaspoons of molasses to the mixture.
  • Olive oil – I love the richness this adds to the muffins, but you can also use sunflower, canola, or melted coconut oil in place of it, if need be.
  • Unbleached all-purpose flour – normally I would offer a gluten-free option for this, but because 99% of the time sourdough starters are made with wheat flour, I don’t think it wise to suggest anything else!
  • Nuts – as mentioned before, I kept nuts out of this recipe to keep it allergy-friendly. But, if you’re a fan, fold 1/2 cup chopped walnuts or pecans into the muffin batter before scooping into the cupcake liners.
  • Loaf – if you’d rather make this into a loaf, use a 9-inch loaf pan and bake for 60-70 minutes, or until the top is nicely browned and an inserted toothpick draws clean.

If you love banana bread but don’t have any sourdough discard, or just like the banana-nut combo, I highly recommend the recipes below!

One-Bowl Sourdough Banana Muffins

Pan with muffins in it next to broken muffin and stick of butter

If you're looking for a great recipe to use up some of your sourdough discard, look no further! These vegan, sourdough banana muffins only need one bowl and a muffin pan to create a delicious snack.

Prep Time 10 minutes
Cook Time 25 minutes
Total Time 35 minutes

Ingredients

  • 3 large, peeled, very ripe bananas (about 320 g)
  • 1 cup (265 g) sourdough discard, room temperature
  • 3/4 cup (125 g) dark brown sugar
  • 1/4 cup (45 g) olive oil
  • 2 teaspoons vanilla extract
  • 1 1/4 cups (160 g) unbleached all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt

Instructions

  1. Preheat oven to 350F and line a cupcake pan with large liners.
  2. In a large mixing bowl place bananas; if they are not super-soft, mash them until mostly smooth. Next, add in sourdough discard, brown sugar, olive oil, and vanilla extract, whisking until well-combined.
  3. Sprinkle flour over the wet mixture, add baking powder, baking soda, and salt, and whisk together until there are no dry clumps. Scoop enough batter to reach nearly the top of each muffin liner (about 1/3 cup).
  4. Bake muffins for 25-28 minutes or until golden-brown on top, and an inserted toothpick draws clean. If you like a crustier muffin top, bake for 28-30 minutes. And that's it! Enjoy!
  5. If you’d rather make this into a loaf, use a 9-inch loaf pan and bake for 60-70 minutes, or until the top is nicely browned and an inserted toothpick draws clean. *Edit: I've also made this into mini-loaves and the baking time was roughly 35-40 minutes!

These are divine! Added a generous cup of frozen blueberries for a blueberry forward muffin. I can't put my finger on why these are so good--the sourdough discard adds a level of tenderness and flavor that makes these next level. I'm not a huge fan of banana bread things, but the addition of blueberries made it so that the banana flavor felt more subtle, like a soft little bit of jazz in the background. Thank you for this gem, Jackie!

The One-Bowl muffins have become my go-to muffin recipe. I'm not a vegan but my family is. I make them for my grandkids and they are the afternoon snack of choice. My daughter was buying fig bars for them but these muffins are healthy, cost pennies, and taste better. I usually add mini chocolate chips or blueberries. Changes: I use avocado oil instead of olive oil and add applesauce to reduce the amount of oil.

Hi! This recipe looks great! Unfortunately, mine didn’t rise at all in the oven :/ could this be because my bananas were quite cold? Thanks for any help!

It definitely could be! I suggest letting your bananas reach as close to room temp as possible, next time. And if you're not confident in your baking powder (like if it's old) that could be a culprit as well.
