Why Do We Love Sourdough Banana Bread Muffins?
Sourdough banana bread muffins are soft, moist, and full of flavor. They combine the sweetness of ripe bananas with the slight tang of sourdough discard. These muffins are perfect for breakfast or a quick snack.
They have a light and fluffy texture and a slightly crispy top. Using sourdough starter makes them easier to digest and adds extra depth to the flavor. Plus, they are a great way to use sourdough discard instead of wasting it!
Why Use Sourdough in Banana Muffins?
Using sourdough starter in banana muffins has several benefits:
- Adds a slight tangy flavor, making the muffins taste richer.
- Helps with fermentation, which makes them easier to digest.
- Creates a light and fluffy crumb for a soft texture.
Difference Between Active Sourdough Starter and Sourdough Discard
- Active starter – Fermenting and bubbly. Best for making sourdough bread.
- Sourdough discard – A byproduct of feeding a starter. Great for muffins and quick breads.
Instead of throwing away sourdough discard, you can use it in this recipe to make delicious, moist banana muffins.
Now that we know why sourdough works so well, let’s discuss the ingredients!

Step-by-Step Guide to Making Sourdough Banana Bread Muffins
Follow these steps to make light and fluffy muffins.

Step 1: Preparing the Ingredients
- Mash ripe bananas in a bowl.
- Melt the unsalted butter and let it cool to room temperature.
- Preheat the oven to 350°F (175°C).
- Line a muffin tin with muffin liners.
Step 2: Mixing the Wet Ingredients
In a large bowl, combine the following ingredients:
- Mashed bananas – The riper, the better for natural sweetness and moisture.

- Melted butter – Brings richness and a tender crumb.
- Eggs – Bind the ingredients and add structure.
- Vanilla extract – Rounds out the flavors with warmth and aroma.
Stir until everything is fully incorporated, creating a smooth, well-mixed batter.
Step 3: Preparing the Dry Ingredients
In a separate bowl, whisk together these key dry components:
- Flour (all-purpose or whole wheat) – The foundation of the muffins, providing structure.
- Baking soda – Acts as a leavening agent, ensuring a light and fluffy texture.
- Cinnamon – Infuses warmth and pairs beautifully with banana.
- Salt – Enhances all the flavors, balancing sweetness.
Mix well to evenly distribute the ingredients evenly, preventing clumps and ensuring the best possible texture in the final muffins.
Step 4: Combining Wet and Dry Ingredients

- Gradually fold the dry ingredients into the wet ingredients.
- Stir until the batter is combined (avoid overmixing to keep it soft and fluffy).
Step 5: Adding Optional Mix-ins
- Fold in mini chocolate chips, chopped walnuts, or both.
Step 6: Baking the Muffins
- Divide the batter evenly into the muffin pan.
- Fill each muffin liner about ¾ full.
- Bake for 18-22 minutes or until a toothpick comes out clean.

Step 7: Cooling and Serving
- Allow muffins to cool in the muffin tin for 5 minutes.
- Transfer to a wire rack to cool completely.
