Sourdough Discard Banana Bread Ingredients
For the Batter
• All-Purpose Flour – Provides structure to the bread; for a different flavor profile, try substituting with fresh-milled flour (soft white wheat).
• Baking Soda – Acts as a leavening agent to help the bread rise; no substitutes are recommended.
• Salt – Enhances flavor; it’s essential for a balanced taste.
• Unsalted Butter – Adds richness and moisture; using softened butter makes mixing easier.
• Brown Sugar – Provides sweetness along with a hint of caramel flavor; coconut sugar can be a lower glycemic substitute.
• Whole Eggs – Binds the ingredients for structure; no recommended substitutes for the best results.
• Sourdough Starter – Contributes a tangy flavor and helps maintain moisture; you can use either an active or inactive starter.
• Overripe Bananas – Adds natural sweetness and moisture; the browner, the better for flavor.
Optional Add-ins
• Chopped Walnuts – Adds a nutty flavor and texture; feel free to substitute with chocolate chips or omit for a nut-free version.
Step‑by‑Step Instructions for Sourdough Discard Banana Bread
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take a 9×5-inch loaf pan and either grease it with butter or line it with parchment paper to make the removal of your delicious Sourdough Discard Banana Bread easy once it’s baked.
Step 2: Whisk Dry Ingredients
In a medium bowl, whisk together 1 ¾ cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt. This mix is vital for structure and flavor, and should be done until well combined. Set this bowl aside as you prepare the wet ingredients.
Step 3: Cream Butter and Sugar
Using a stand mixer, cream together ½ cup of softened unsalted butter and ¾ cup of brown sugar until the mixture is smooth and fluffy, which should take about 2-3 minutes. This step adds richness to your Sourdough Discard Banana Bread, creating a delightful buttery base.
Step 4: Mix in Eggs and Sourdough
Next, add in 2 whole eggs and 1 cup of your sourdough starter to the butter-sugar mixture. Mix everything together on medium speed until fully incorporated, ensuring a homogenous blend. The batter should appear creamy and slightly airy.
Step 5: Incorporate Mashed Bananas
Now, mash 2-3 overripe bananas in a separate bowl until smooth and add them to your batter. Gently mix the mashed bananas in until just combined, adding natural sweetness and moisture, which are key for the texture of your Sourdough Discard Banana Bread.
Step 6: Fold in Dry Ingredients
Gradually fold the dry mixture into the wet batter using a spatula. Stir gently until the dry ingredients are just combined to prevent overmixing; you want the mixture slightly lumpy for the best texture.
Step 7: Add Optional Mix-ins
If desired, incorporate ½ cup of chopped walnuts or chocolate chips to the batter at this stage. Gently fold them in to distribute evenly throughout without overworking the dough. This step adds extra flavor and texture to enhance your Sourdough Discard Banana Bread.
Step 8: Transfer and Bake
Pour the batter into your prepared loaf pan, smoothing the top with a spatula. Place the pan in the preheated oven and bake for 60-65 minutes. Keep an eye on the top; if it browns too quickly, lightly cover it with aluminum foil.
Step 9: Cool Before Slicing
Once baked, check doneness by inserting a toothpick into the center—it should come out clean. Remove the bread from the oven, and let it cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely before slicing. Enjoy this moist and tangy Sourdough Discard Banana Bread!

- Use Overripe Bananas: Ensure your bananas are well-mashed and at least 70% brown to achieve optimum sweetness and moisture in your bread.
- Avoid Overmixing: To prevent a dense loaf, gently fold in the dry ingredients until just combined. The batter should remain slightly lumpy for the best texture.

Sourdough Discard Banana Bread Recipe FAQs
How do I choose the right overripe bananas?
Absolutely! When selecting bananas for your Sourdough Discard Banana Bread, look for ones with brown spots all over or even a bit of black on the peel. The more overripe they are, the sweeter and moister your bread will be. If they’re still slightly green or firm, just let them sit at room temperature until they reach that perfect brown shade.
What’s the best way to store Sourdough Discard Banana Bread?
To keep your banana bread fresh, store it in an airtight container at room temperature for up to 3 days. If you want to extend its shelf life, wrap it in plastic wrap and then aluminum foil before placing it in the fridge for up to a week. For long-term storage, freeze it! Wrap the cooled loaf tightly and it can last for up to 3 months. Just thaw in the fridge overnight when you’re ready to enjoy.
Can I freeze Sourdough Discard Banana Bread? If so, how?
Yes, you can definitely freeze your Sourdough Discard Banana Bread! I recommend wrapping your cooled bread tightly in plastic wrap first, then in aluminum foil to prevent freezer burn. It will keep well for up to 3 months. When you’re ready to savor it, just place it in the refrigerator overnight to thaw, or gently microwave a slice for about 10-15 seconds for a quick, warm treat.
What if my banana bread turns out dense?
Very! If you find your Sourdough Discard Banana Bread is denser than expected, it might be due to overmixing the batter. Remember, after incorporating the dry ingredients, mix just until combined—some lumps are perfectly fine! Also, ensure your bananas are ripe enough and properly mashed to increase moisture levels and keep that delightful tender crumb.
Are there any dietary considerations I should be aware of?
Yes! If you’re baking for someone with allergies, be sure to note that this banana bread contains gluten from the all-purpose flour and dairy from the butter. You can easily swap the butter for a dairy-free alternative like coconut oil or applesauce, and use gluten-free all-purpose flour to make it suitable for those with gluten sensitivities. Additionally, if you’re using optional add-ins like walnuts, always check for any nut allergies in your group.
Can I use other types of flour in my Sourdough Discard Banana Bread?
Absolutely! While all-purpose flour is the go-to for this recipe, you can substitute half of it with whole wheat flour for added nutrition and a denser texture. If you’re experimenting with fresh-milled flour, just be mindful it might alter the moisture retention and baking time, so keep a close eye on your bread as it bakes!
