    Sourdough discard banana bread is so incredibly soft and bursting with banana flavor. The discard gives this iconic bread the perfect rise and texture. Put this powerful ingredient to work by incorporating it into your next loaf of banana bread. Don't let your extra sourdough discard, or overripe bananas, go to waste anymore.

    What is there not to love about banana bread? It has to be the best and most popular quick bread. And for good reason. This recipe is a great way to use both your leftover starter and those overly ripe bananas. It's just like traditional banana bread, but with a twist.

    This version of banana bread has all the classic flavors and tastes or regular banana bread but is made with an unfed sourdough starter or what is typically called the discard. The sourdough starter discard is added to give it the perfect rise and texture.

    What is a sourdough starter? A sourdough starter is a mix of flour and water that over time has fermented and come to life. When it is added to baked goods it acts as a leavening agent. Just like baking powder, soda, or yeast.

    It is mostly used in making sourdough bread, but can also be used in lots of different ways. Learn how to make your own sourdough starter.

    What does discard mean? A sourdough starter is ready to be used, and at its full baking power, about 6-8 hours after it has been "fed." After this point, it falls and loses some of its baking potential for bread, like a loaf of sourdough, and needs to be fed again.

    Learn everything you need to know about a discard and other recipes to try.

    When a portion is removed to be fed what is left over is referred to as the discard. Some will dump it but others will harness what baking potential it still has. That's where this sourdough banana bread recipe and my other sourdough recipes come in handy! Next time you have an unfed starter sitting around whip up a loaf of this bread.

    Ingredients

    Everything you need to make this banana bread.

    All the ingredients for banana bread. Vanilla extract, sugar, sourdough starter, yogurt, butter, eggs, salt, baking soda, cinnamon, overly ripe bananas, flour.

    Dry Ingredients

    • All Purpose Flour
    • Salt
    • Baking Soda
    • Cinnamon
    • Sugar

    Wet Ingredients

    • Butter
    • Yogurt
    • Sourdough Starter Discard
    • Vanilla Extract
    • 2 Large Egg
    • Ripe Mashed Banana, the softer the better.

    Notes on ingredients:

    When measuring the flour make sure to scoop flour out with a spoon into the measuring cup and level with a knife.

    This recipe calls for about 2 cups of mashed bananas. That will be about 4 larger size bananas. The softer the banana the better. If they are too firm it will be difficult to mash.

    Make sure butter is soft and at room temperature. The butter and sugar need to be creamed together. Softer butter will allow it to come to a creamy consistency. You shouldn't see any lumps of butter.

    Full ingredient amounts and notes in the recipe card.

    Instructions

    Preheat oven to 350 degrees Fahrenheit.

    Prepare a loaf pan by spraying with non-stick spray or a coating of butter with a dusting of flour. Whichever way you prefer to prepare baking pans. Set aside.

    In a small bowl, mix together the flour, salt, baking soda, and cinnamon. Set aside.

    In a large glass bowl, mix together the butter and sugar with a hand mixer until it's fully combined and has a soft, fluffy texture.

    Next, add in the yogurt, sourdough starter, and vanilla extract. Mix well with a hand mixer until everything is fully combined.

    Add in eggs and mix again with the hand mixer just until they are fully incorporated. Don't overmix.

    In a medium bowl mash bananas with a fork until they are a creamy consistency. Some smaller lumps are okay. The softer the bananas are the easier they will be to mash.

    With a wooden spoon or spatula, fold in the mashed bananas just until everything is fully incorporated.

    Dump in the flour mixture, and with a wooden spoon, fold everything together until the flour is fully incorporated. Use a spoon or spatula at this point because we don't want to overmix the batter. That can lead to a dense texture.

    Pour batter into the prepared 9 x 5-inch loaf pan and using a spoon or spatula scrape the bottom of the bowl so all the batter makes it in the pan.

    Give the pan a good shake so the batter settles and is evenly distributed. The top of the batter should be even and as smooth as possible. You can also use a spatula to spread it out.

    Place pan in the preheated oven and bake for 55-60 minutes. About halfway through if the top of the bread starts to turn golden brown, make a tent out of tin foil and place it over the top. This will allow the inside of the bread to continue to cook but will protect the top from burning.

    The bread is done when a toothpick is inserted into the center of the loaf and comes out clean.

    When done, place the pan on a wire rack and allow the bread to cool inside the pan for 10 minutes.

    Take a knife and run it between the bread and the side of the pan. Just to get any piece that may be stuck.

    Remove loaf from the pan and allow it to cool. If you can wait...

    Slice and serve with a little butter and enjoy!

    Variations

    Add a special touch to your bread by adding in either chocolate chips or chopped walnuts. About a cup of either.

    This bread does stand on its own, but every now and then we do enjoy the addition of chocolate chips. Especially my kids.

    Equipment

    Hand mixer: A stand mixer can also be used with the paddle attachment. I find a hand mixer works great.

    Glass Bowls: A few different-sized bowls to mix this batter.

    • Large mixing bowl for the butter and sugar and eventually all the mix
    • Small-Medium to mash bananas
    • Small-Medium to mix flour.

    Loaf Pan: 9"x5" nonstick loaf pan.

    Storage

    Banana bread will last 3-4 days on the counter and up to a week in the refrigerator. To store, make sure the bread has completely cooled. I like to wrap mine in aluminum foil, plastic wrap, or place it in a cake stand with a lid to keep it fresher.

    Can banana bread be frozen? Yes! I love to freeze banana bread. I will often make two loaves and freeze one to keep for future camping trips.

    To freeze make sure the loaf is completely cool, wrap tightly in aluminum foil, and then place in a gallon zip lock bag or airtight container. Make sure to remove as much air as possible and stick it in the freezer.

    It will last a long time in the freezer but is best to be used within 3-4 months.
