Ingredients and substitutions
- All-purpose flour
- Unsalted butter
- Sugar
- Honey: I prefer to cut down on refined sugar a bit, but you can just use an additional 1/2 cup of sugar.
- Sourdough discard: if you do not have sourdough starter/discard, you can omit from the recipe! I would then only use 1 1/2 cups of flour since you are removing some of the liquid.
- Plain Greek yogurt: You can swap this for unsweetened, plain whole milk yogurt or a vegan Greek-style yogurt.
- Bananas: You want them to be very ripe.
- Blueberries: You can use frozen or fresh.
- Baking soda
- Baking powder
- Apple cider vinegar: You can’t taste this in the recipe, but it’s used as an acid to make the leavening agents work better. You can use white vinegar instead.
- Vanilla extract
- Salt
How to make eggless sourdough discard banana blueberry muffins

Step one: Preheat oven to 350 degrees and grease/line a muffin tin. In a large stand mixer, combine butter, sugar, honey, Greek yogurt, mashed bananas, vanilla, apple cider vinegar and sourdough discard. Mix until well combined. Add in the flour, salt, baking soda, and baking powder. Mix together. Gently fold in blueberries.

Step two: Scoop into muffin tin, filling each cup about 3/4 of the way up. Bake for 20-25 minutes.
FAQ
When you bake sourdough items you have an “active” sourdough starter which is simply just flour and water. You have to add flour and water to this mixture frequently to “feed” it. Once the flour and water are added and its fed, then the sourdough starter becomes active, bubbly and you can bake with it. In order to not have a crazy amount of sourdough starter, you typically remove some of it before feeding it. This removal is called “discard” because often people discard it in the trash. However, this discard that is unfed sourdough starter can be used in recipes like this!
I would really recommend keeping the bananas as they keep the recipe at a good consistency. The blueberries could be subbed out for chocolate chips or raspberries.
Yes! The use of Greek yogurt and the two leavening agents provide the perfect substitutes for eggs.
Likely your eggless muffins are dense from overmixing. Once the flour is added to the batter, mix until just combined. Don’t overmix. Also make sure your baking powder and baking soda aren’t expired.
No – they taste very similar to standard muffins that include eggs.
Why these muffins work without eggs
When replacing eggs in a recipe, you need to replace all the functions of an egg which include moisture, binding, and rise. In this recipe, Greek yogurt and bananas is used for moisture and binding. There are 3 ingredients that help the muffin rise including baking soda, baking powder, and apple cider vinegar. Check out this guide for the best egg substitute in muffins.
One of the best parts about these eggless muffins is that you do not need flax eggs, chia seeds, or commercial egg replacers. Simple ingredients like Greek yogurt, baking powder, and vinegar help create soft, fluffy muffins without eggs.
More eggless muffin recipes
Another great use for sourdough discard are these eggless sourdough discard chocolate chip pumpkin muffins. I also cannot recommend these classic Eggless Lemon Blueberry Muffins or these Eggless Chocolate Chip Muffins. Lastly, one of my favorite muffins to make for my kids include these Eggless Applesauce Muffins.
Allergy-Friendly Substitutes
To make this recipe dairy-free: Substitute butter for a vegan butter (firm block not a spreadable kind). Use a vegan Greek-style yogurt
To make this recipe gluten-free: Use a gluten-free flour blend. Add 1 teaspoon of xanthan gum. Only add 1/2 teaspoon if your flour already contains xanthan gum.

Equipment Needed
- Stand mixer or handheld electric mixer.

great recipe!!
I’m so glad you enjoyed the muffins! Thanks so much for the review. Happy baking!
A family favorite recipe and they are gone quickly as my kids love them!
Soft and turned out well overall. However, lacking flavor for me. Even with overripe bananas (I used 3 actually) and adding vanilla from the start. I may try again but adding spices to it.
Thank you for your feedback! It is always helpful to me to hear your feedback as I am currently working on some more muffin recipes.
It was a nice simple recipe. The muffins turned out yummy!
Thank you! I’m so glad you enjoyed them!
I baked these and they were delicious! They do look nice and taste even better. My family gobbled them up and I found myself wanting to feed my starter so I had discard to make more.
