If you make gluten-free sourdough bread, you must have some sourdough starter discard. Don’t throw it away, use it to make these Blueberry Banana Sourdough Muffins!
I have so much gluten-free sourdough starter discard that I have to be creative with it. I hate wasting food and we can only eat so much sourdough pancakes. So, I had to experiment with making muffins using the “discarded” sourdough starter.
I must tell you, gluten-free baking is tricky, I had to experiment with these muffins so many times. (That’s how much sourdough starter discard I had. Haha!)
Who would’ve thought that I’d be baking gluten-free goodies, when just a couple of years I ago, I did not even know what gluten was!

The gluten-free flours used in this recipe are: brown rice flour, chickpea flour and cassava flour.
Cassava flour is one of the flours I discovered (and learned to make at home) through the Gluten Free Baking Academy. It provides a very nice crumb to these muffins.
If you can’t find cassava flour, you can substitute arrowroot starch instead, the crumb won’t be the same though, but the muffins are still yummy.
Chickpea flour is also known as garbanzo flour.
Check out this great guide to gluten-free flours from the Academy of Culinary Nutrition.
This recipe uses 1 egg. Try to get pastured eggs if you can. You can really see the difference in the egg yolk vs. a conventional egg. For a vegan option, you can omit the egg entirely too! The bananas can also serve as the egg replacement.
When you make sourdough, you’ll have to “feed” the sourdough starter every day or so to keep it active and bubbly. You’ll need to “discard” some starter so you won’t end up feeding it too much flour. This discard can be given to a friend who wants to make their own starter, used to make sourdough pancakes or these delicious sourdough muffins.
You can use live, freshly discarded or refrigerated sourdough starter. The gluten-free sourdough starter I used for this recipe was kept in the fridge for a few days and was no longer bubbly like active starter.
Making the Sourdough Muffins
Pre-heat the oven to 350ºF and place unbleached liners into a muffin tin.
In a large mixing bowl, combine all the dry ingredients together.
In another bowl, add the ripe bananas and mash them. Then add the egg, coconut oil, maple syrup, vanilla, lemon juice or apple cider vinegar, sourdough starter and water. Mix until everything is combined.
Slowly add the wet ingredients to the dry ingredients. Mix thoroughly. I used a stand mixer.
Carefully fold in the blueberries. I used frozen wild blueberries. You’ll have to act quickly here if you’re using frozen blueberries, don’t let them defrost or you’ll end up with purple muffins.
I used a 1/4 cup to scoop the muffin mixture into the muffin pan.
Place into the oven and bake for 25 minutes.
Let them cool completely on a cooling rack.
These gluten-free blueberry banana sourdough muffins are great for breakfast or as a snack! Try it with some ghee too. So yummy!
