Why Make This Recipe
First, why not? This banana bread checks all the boxes. It’s easy to make, and your kitchen will thank you for the minimal cleanup. Plus, you’ll impress everyone with your baking skills—really, who knew sourdough could be this versatile? And let’s face it, hiding those overripe bananas in the back of your kitchen just won’t cut it anymore.
Ingredients
You don’t need fancy stuff — just these basics!
- 2 pieces ripe bananas, mashed (The riper the bananas, the sweeter and more flavorful the bread will be.)
- 1 cup sourdough starter (Ensure your sourdough starter is well-fed for best results.)
- 1/2 cup sugar
- 1/4 cup butter, melted
- 2 large eggs (For a vegan version, use flaxseed eggs.)
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 1/2 cups all-purpose flour (Can substitute with whole wheat flour for a healthier option.)
Directions
- Preparation: Preheat your oven to 350°F (175°C). Grease a loaf pan or line it with parchment paper for easy removal.
- Mix Ingredients: In a large mixing bowl, combine the mashed bananas, sourdough starter, melted butter, sugar, eggs, and vanilla extract. Mix until smooth.
- Add Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry mix to the wet ingredients, stirring until just combined.
- Bake: Pour the batter into the prepared loaf pan. Bake for about 50-60 minutes, or until a toothpick comes out clean. Let it cool in the pan for 10 minutes before transferring it to a wire rack.
- Enjoy: Slice and dig in while it’s still warm, but really—waiting is for suckers!

How to Make Sourdough Banana Bread (Overview)
Making Sourdough Banana Bread is a walk in the park. Start by mixing your wet ingredients in one bowl, then combine the dry ones in another. This way, you avoid over-mixing—which can lead to a dense loaf (yikes!). Pro tip: Use a spatula instead of a whisk to gently fold in the flour. It’s all about that light, fluffy texture.
How to Serve Sourdough Banana Bread
The best way to enjoy Sourdough Banana Bread? Fresh, warm, and slathered with a bit of butter. Picture this: golden slices with a hint of caramelized sugar, the aroma of warm banana, and that delightful tang from the sourdough—it’s simply irresistible. You can also serve it with a scoop of ice cream for a decadent dessert or alongside your morning coffee for a cozy breakfast.

How to Store Sourdough Banana Bread
This banana bread keeps well for about 3-4 days at room temperature. Just wrap it tightly in plastic wrap or keep it in an airtight container. For longer storage, pop it in the fridge, or freeze it for up to 3 months. When you’re ready to enjoy, just let it thaw at room temperature or microwave a slice for a few seconds. Easy peasy!
Tips to Make Sourdough Banana Bread
- Use overripe bananas: The sweeter, the better!
- Stir like you mean it: Mix your wet and dry ingredients separately to avoid lumps.
- Let it cool before slicing: You’ll get prettier slices that way.
- Experiment with add-ins: Nuts, chocolate chips, or dried fruit can add a special touch to your loaf.
Variation
Want to switch things up? Toss in some chocolate chips for a gooey addition or use a combination of spices like cinnamon and nutmeg for a cozy fall flavor. If you’re feeling adventurous, you can even add walnuts or coconut flakes for an extra crunch. Going vegan? Just swap in flaxseed eggs to keep things simple.
