These Healthy Sourdough Banana Muffins use sourdough discard to make them extra fluffy and flavorful. Full of whole grains, fiber and protein, and naturally sweetened with maple syrup, your whole family will love these muffins!

I was a few years late to the sourdough revolution, but for the last two or so years, I have been experimenting with baking sourdough bread. One thing that happens when you start using a sourdough starter is that you start to want to use sourdough in EVERYTHING. Since muffins are one of the things I bake most often in my house, it made sense to develop a muffin recipe that uses sourdough discard.
What is sourdough discard?
Sourdough discard is the excess removed from a sourdough starter before “feeding” it. When I feed my sourdough starter, I normally keep 50 grams of starter, then mix in 50 grams of water and 50 grams of flour. Whatever extra sourdough starter I have above the 50 grams is the “discard”. You can either throw that away, or use it to add extra flavor to other recipes such as crackers, waffles or in this case, muffins!

Ingredients for Healthy Sourdough Banana Muffins
Dry ingredientsย
White Whole Wheat Flour – this flour has a lighter texture than regular whole wheat flour. I use King Arthur Brand, and they now label this flour as “golden wheat“. You can substitute whole wheat pastry flour, all-purpose flour or regular whole wheat flour, however they will be a bit more dense with regular whole wheat flour.
Baking Powder AND Baking Soda – yes you need both and no they are not the same thing. These are what makes the muffins rise and get light and fluffy.
Fine sea salt – necessary for flavor
Ground cinnamon – this is optional but I prefer it for flavor.
Wet ingredients
Mashed Bananas – most of my muffins only use 2 bananas, here I used 3 for lots of banana flavor. Use very ripe, brown and spotty bananas.
Melted Butter – this makes a big difference in flavor and texture
Pure Maple Syrup – adds natural sweetness
Eggs – for leavening and structure
Plain Greek Yogurt – adds moisture and flavor, as well as tenderness.
Sourdough discard – can be fed or unfed
Vanilla extract – for flavor
Mini Chocolate Chips – optional if you don’t want to add the extra sugar, but very delicious and my kids love them.


How to make muffins that are fluffy, not tough and dense
There is a secret to making muffins that are fluffy instead of dense and tough โ itโs called the muffin method and itโs important! The muffin method is just mixing the dry ingredients, mixing the wet ingredients in a separate bowl, and then pouring the wet ingredients into the dry ingredients. Stir the wet and dry ingredients until just mixed. It is very important not to over mix here. Overmixing produces more gluten, which is what gives you tough and dry muffins.

Tips for making the best Healthy Sourdough Banana Muffins
- The most important tip that I can never say enough isย DONโT OVERMIX YOUR BATTER. This is why we first mix the dry ingredients really well, then mix the wet ingredients really well, then add them together and carefully mix until just combined and you donโt see any dry spots of flour anymore.
- Start with a hotter temperature, then reduce after 5 minutesย โ we start at 425 degrees F and then after baking for just five minutes, then keeping the muffins in the oven, reduce the heat to 350 F. The initial blast of heat activates the baking powder and will help the muffins rise higher.
- Donโt use paper linersย โ only use parchment liners, or spray the muffin tins liberally with cooking spray and use no liners. I swear byย THESEย parchment paper liners.

How to freeze sourdough banana muffins
These muffins freeze beautifully. Allow the muffins to cool completely on a rack before freezing. Then they can be individually wrapped in plastic wrap if you like and stored in a freezer bag. They will keep for up to one month.
Helpful equipment for making muffins
- Food Scale – for measuring by weight
- Muffin Tinย โ this is my favorite.
- Parchment Paper Linersย โ I swear by these
- An ice cream scoopย โ for easily portioning out the batter.
- Whole wheat pastry flourย orย White Wheat Flour.

Instructions
- Preheat oven to 425ยฐF degrees. Line a 12-count muffin pan with parchment (not paper) muffin liners or spray with nonstick spray. Set aside.
- In a medium bowl, whisk together the flour, cinnamon, baking soda, baking powder, salt, set aside.
- In a second, larger bowl, mix the mashed bananas, sourdough starter, maple syrup, yogurt, egg, melted butter, and vanilla together until smooth.
- Pour the dry ingredients into the wet ingredients and stir until just combined. Do not overmix the batter or you will have tough muffins.
- Set aside about 1/4 cup of mini chocolate chips if you are going to sprinkle them on the muffin tops. Mix the remaining 3/4 cups of mini chocolate chips into the batter, only stirring once or twice to mix them in, don't over mix.
- Evenly distribute the batter between the muffin cups. (I use an ice cream scoop for easy portioning). Sprinkle some mini chocolate chips on top of each muffin if you want. Muffin cups should be filled almost to the top.
- Bake for 5 minutes at 425ยฐF degrees. Keeping the muffins in the oven, reduce the oven temperature to 350ยฐF and continue to bake for another 12-17 minutes or until a toothpick inserted in the center comes out clean. When done, remove from the oven and transfer the muffins to a cooling rack as soon as possible.
