Ingredients
There are only a few key ingredients you'll need to pull these Sourdough Discard Banana Muffins together.

- Sourdough discard: The discard should be unfed and at room temperature for this recipe. This recipe is designed for a sourdough discard with a 1:1 ratio (when you feed your starter, it's with 1 part water and 1 part flour). If your starter uses a different ratio, you may need to adjust some of the ingredients.
- Learn more about how to make a sourdough starter.
- Bananas: Overripe bananas are ideal! They'll be mashed to go into the batter, so the soft spots will be fine. I also like to leave the bananas fairly chunky when mashing as they soften a lot while baking and you won't notice the chunks.
See full recipe below for detailed directions.
Substitutions & Variations
This is a very adaptable recipe! Below are a few variations to try:
- Use active sourdough starter - If you want to use active sourdough starter rather than discard, you can! Replace the sourdough discard with active starter (200g). Be prepared that your muffins may rise more than those made with discard.
- Add oats - Instead of turbinado sugar, top your muffins with a sprinkling of old-fashioned oats for a different texture.
- Add nuts - Add ¼ cup chopped walnuts or almonds to the batter before diving into muffin cups.
- Add chocolate chips - Add ½ cup chocolate chips to the batter.
- Add blueberries - If you want a blueberry banana version of this recipe, reduce the bananas to ½ cup (approximately 1 banana), and add ½ cup fresh blueberries.

How to Make Sourdough Discard Banana Muffins
Sourdough Discard Banana Muffins come together in just a few easy steps! The full recipe with detailed directions is at the bottom of this post.

- Step 1: Cream together the butter and granulated sugar until light and fluffy, about 2 minutes.

- Step 2: Add the egg and vanilla extract and mix to combine.

- Step 3: Mix together the dry ingredients in a medium mixing bowl.

- Step 4: Add the sourdough discard, mashed bananas, and dry ingredients to the butter mixture. Stir slowly until incorporated, then increase speed to medium until a uniform batter forms.

- Step 5: Line a 12-cup muffin pan with muffin liners. Fill each cup about ⅔ full with batter. Using a cookie scoop helps make filling easier!

- Step 6: Sprinkle the batter with turbinado sugar for a crunchy topping and bake for 30-35 minutes until a toothpick inserted in the center comes out clean.
- Step 7: Let the muffins cool for a few minutes in the pan, then serve or transfer to a cooling rack to cool fully.
Expert Baking Tips
- Use a cookie scoop to fill the muffin cups - it makes it easier!
- Make sure to line the muffin cups with muffin liners so the muffins don't stick to the pan. If you'd rather not use liners, make sure to spray the muffin cups with cooking spray.
- When finished, the muffins should be golden brown and a toothpick inserted in the center will come out clean.
- Let the muffins cool for a few minutes before serving - this will make it easier to cut them in half and spread with butter or other toppings.

Storage
Room Temperature Storage: Store these muffins in an airtight container at room temperature for up to 3 days. You can reheat them in the microwave for 15-30 seconds to make them soft and warm again.
Freezer Storage: Muffins also freeze well. Once they are fully cooled, transfer to an airtight container or bag and freeze for up to 3 months. To reheat, let the muffins thaw at room temperature, then reheat in the microwave for 30-60 seconds.
Recipe FAQs
I highly recommend using muffin liners. If you'd rather not, make sure that you grease the muffin pan thoroughly before adding your batter.
If your muffins are sticking to the liners, let them cool for a few mintues! After the muffins have cooled, they will no longer stick to the liners.

This recipe was so good and what an easy way to use up bananas and discard! This is my third recipe of yours that I've made over the last few days and I think I'm a little obsessed now! They've all turned out absolutely perfectly. Thanks for such amazing recipes!!!!!
Jessica Vogl says
I love to hear that! Thank you!
Ashley says
These are so good! I'm wondering if the sugar can be replaced with honey. If so, how much honey would you use?
Jessica Vogl says
So glad you like them! I think it could work, but it wouldn't be an easy substitution (honey is sweeter than sugar, so you wouldn't need as much, and then you'd need to adjust other ingredients in the recipe to accommodate more liquid from the honey, etc.).
