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.

FAQ

What is sourdough discard?

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!

Can I use other fruit?

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.

Are these muffins eggless?

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.

Notes

This recipe was updated in May of 2025: to updated photos and add the addition of baking soda and apple cider vinegar for an increased rise in the muffins.
Overly ripe bananas work best in this recipe.
Try not to overmix the batter as it can create dense muffins.
Store in airtight container on counter for up to 4 days. Place in a single layer in a freezer bag for about 3 months.

    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.

    1. 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.

  2. 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.
