What You’ll Need for Sourdough Banana Bread

Creating a loaf of Sourdough Banana Bread is all about using quality ingredients that harmonize beautifully. Each component has its role, from the fluffy all-purpose flour that creates structure, to the ripe bananas that bring sweetness and moisture. The sourdough starter is the star here, adding that lovely tang and making the bread rise beautifully. Let’s dive into what you’ll need to make this delicious bread!
- 1-1/2 cups all-purpose flour (170 grams) – This flour provides the necessary structure for the bread. You can use all-purpose or even whole wheat for a different flavor profile.
- 1 teaspoon baking soda – This helps the bread rise and gives it a fluffy texture.
- 1 teaspoon kosher salt – Enhances the flavors of all the ingredients.
- 1 teaspoon ground cinnamon – Adds warmth and depth to the flavor.
- 3/4 cup brown sugar (160 grams) – Provides sweetness and moisture, as well as a slight caramel flavor.
- 1/2 cup unsalted butter, room temperature (113 grams) – Adds richness and helps keep the bread moist.
- 1 large egg – Binds the ingredients together and adds moisture.
- 1 cup unfed sourdough starter discard (227 grams) – The key ingredient that gives this bread its unique flavor and texture.

Recipe Directions for Sourdough Banana Bread

Making Sourdough Banana Bread is a delightful experience, filled with the comforting aromas of baking. Follow these straightforward steps to create your very own loaf at home.
- Preheat your oven to 350 degrees F and spray a 9×5 loaf pan with non-stick spray. This step ensures your bread doesn’t stick and comes out beautifully.
- In a medium-sized mixing bowl, add 1-1/2 cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon kosher salt, and 1 teaspoon ground cinnamon. Whisk these dry ingredients together until well combined, and then set the bowl aside.
- In the bowl of an electric mixer, cream together 3/4 cup brown sugar and 1/2 cup unsalted butter. Mix until the mixture is light in color and fluffy in texture, which should take about 2 to 3 minutes.
- Scrape down the sides of the bowl and mix in 1 large egg, 1 cup unfed sourdough starter discard, 1 cup mashed ripe banana, and 2 teaspoons vanilla bean paste. Mix gently until just combined, being careful not to overmix.
- With the mixer on low speed, start adding in the flour mixture slowly. Continue mixing just until the batter comes together. You want it to be well combined without overworking the dough.
- Once your batter is mixed, spread it evenly into the prepared loaf pan. Make sure to smooth the top with a spatula for an even bake.
- Bake in the preheated oven for 60 to 75 minutes. You’ll know it’s ready when a toothpick inserted into the center comes out clean, or the loaf registers 200F to 205 degrees F with an instant-read thermometer.
- Once baked, remove the bread from the oven and let it cool in the pan for about 10 minutes. Then, carefully transfer it to a wire rack to cool completely. This cooling period helps the flavors develop even more.
- Slice your delicious Sourdough Banana Bread once it’s cooled and enjoy! You can serve it plain or with a pat of butter for a delightful treat.
Things Worth Knowing
- Keep an eye on the bananas: Ripe bananas are key! The riper they are, the sweeter and more flavorful your bread will be.
- Don’t overmix: Once you combine the wet and dry ingredients, mix just until incorporated. Overmixing can lead to a dense loaf.
- Test for doneness: Use a toothpick to check the center. If it comes out clean, your bread is ready!
- Storage matters: Store the bread in an airtight container to keep it fresh. It can last up to a week on the counter.
- Freezing for later: You can freeze your banana bread! Just wrap it tightly in plastic wrap and foil before placing it in the freezer.
