Ingredients
- All-purpose flour: Adds to the light texture.
- Unsalted butter
- Sugar: to sweeten.
- 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
- Plain Greek yogurt: Used as a binding agent and an egg substitute.
- Bananas: Mashed with a fork.
- Blueberries: You can use frozen or fresh.
- Baking soda: Since you are using sourdough discard, this will give it a nice rise.
- Baking powder: Yes, you will use both SODA and POWDER. As these muffins are eggless, these will give them a nice rise.
- Apple cider vinegar: You can’t taste this in the recipe, but it’s used as an acid to react with the baking soda and activate the baking soda.
- Vanilla: Adds delicious flavor.
- Salt: to enhance flavor.
How to make sourdough discard banana blueberry muffins

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.

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.
Substitutions
Honey – you can add additional sugar or use maple syrup
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.

Equipment Needed
Stand mixer OR handheld electric mixer (if you do not have these items, then grab a whisk and some elbow grease!)

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.
