What's in these Muffins?
Sourdough Discard- What is sourdough discard? When you feed your sourdough starter you discard part of it, because if you were to keep feeding your entire starter every time, you would have a literal ton of starter, and when baking you really only need a few ounces. Instead of throwing the extra done the drain, use it to bake! It adds moisture and a little bit of tang to baked goods. After you feed your starter, keep the extra discard in a separate container in the refrigerator and use it whenever you bake. If you need some excellent tips on how to keep a sourdough starter, Deanna over at Homesteadandchill.com has some amazing step by step directions.
Bananas- Make sure the bananas are pretty brown and spotty for this recipe. The spottier they are the sweeter they are. There is brown sugar in this recipe, but the brown bananas add even more sweetness. If you have frozen bananas you could use those too. Defrost them to room temperature and then discard any of the extra liquid that may have come out of them during the freezing process.
Walnuts- This is optional, but I think the walnuts add a nice crunch and texture to these muffins. Bananas and walnuts are a classic combination. If you don't have walnuts, you could use pecans as well. Almonds might be really delicious too.
Cinnamon- This recipe is heavy on cinnamon. I think banana and cinnamon are a fantastic combination. You can add vanilla to this recipe if you wanted as well. I think the cinnamon brings out a little more of the banana flavor. So good!

How Do You Make These Muffins?
Preheat the oven to 400 degrees. In a small bowl, peel the bananas and mash them. You want them to be very pureed. Set that bowl aside.
In another small bowl, mix all the dry ingredients together and mix well. Set that aside.






In a medium bowl, add the brown sugar and melted butter. Mix that to combine well. Next, add the eggs, one at a time, mixing well between each addition. Add the sourdough starter and continue to mix everything well. Pour in the sourdough starter and mix well. Next, you will add the bananas and cinnamon. Mix that well to combine everything.
Next, you will add in the dry ingredients. You want to be really careful when mixing in the dry ingredients that you do not overmix. The muffins should just come together with about five folds of the batter. If you overmix, the muffins will be tough and not have a nice, fluffy texture.
Add the walnuts if you are using them and mix one final time.
Line a muffin tin with muffin liners and scoop the batter into each of the liners. Try to get the batter as even as possible into the muffin tins. Bake for 20-22 minutes depending on your oven. When you stick a toothpick into the muffin, it should come out clean. Take them out of the muffin pan and allow them to cool on a wire rack. Serve with your favorite butter and jam! Enjoy!




Questions About These Muffins?
Sure! Instead of butter, you can use coconut oil or vegetable oil. Either would work perfectly in this recipe.

These muffins will keep in an airtight container or a Ziploc bag for about three days on the counter. If you want to freeze them, place them in a Ziploc bag and freeze them for up to three months. To defrost, place them in the toaster for a few minutes and they should come up to temperature quickly.
