Ingredients You’ll Need

I love how these ingredients come together — simple pantry staples that transform into a lush bread. When shopping, look for really ripe bananas to get the sweetest flavor, and use an active sourdough discard that you’ve built up in your fridge.

• Ripe Bananas: The riper, the better for natural sweetness and moisture.
• Sourdough Discard: Adds a lovely tang and tender crumb; no need to feed, just toss it in.
• Unbleached All-Purpose Flour: Gives a neutral base without extra additives.
• Baking Soda: Helps with leavening and browning.
• Baking Powder: Boosts the rise and keeps the bread airy.
• Salt: Balances sweetness and enhances flavor.
• Unsalted Butter: Adds richness and a soft crumb.
• Light Brown Sugar: Brings moist sweetness and depth; monk fruit brown sugar is a great swap!
• Egg + Egg White: Eggs add structure, with an extra white for a better rise.
• Vanilla Extract: For that warm, fragrant touch.
• Baking Spray & Parchment Paper: To prevent sticking and help with easy loaf removal.

Variations

One of the many reasons I keep coming back to this sourdough discard banana bread recipe is how easy it is to personalize. Feel free to add or swap ingredients to suit your mood or dietary needs — I encourage you to make it your own!

• Add Nuts or Chocolate Chips: My family goes crazy for a handful of chopped walnuts or dark chocolate chips stirred into the batter — it adds wonderful texture and flavor.
• Gluten-Free Version: Use a 1:1 gluten-free blend in place of all-purpose flour, but be sure to check the consistency of your batter—it might need a touch more discard or milk to stay moist.
• Sweetener Swaps: Try coconut sugar or maple syrup instead of brown sugar for a twist in flavor and color.
• Spice It Up: Cinnamon, nutmeg, or even a pinch of cardamom can make this feel more like a cozy autumn treat.

How to Make Sourdough Discard Banana Bread Recipe

Step 1: Prep Your Pan Like a Pro

Start by preheating your oven to 350°F — you want it nice and steady when the batter’s ready. Spray a metal loaf pan with baking spray, then line it with parchment paper, leaving some overhang on the long sides. This little trick helps you lift the loaf out effortlessly once it’s baked, no scraping or crumbling required.

Step 2: Mix Your Banana and Sourdough Discard

Mash the bananas in a medium bowl with a fork until mostly smooth but still a few chunks remain — that texture is so comforting. Then stir in your sourdough discard; this blend is the heart of your bread’s unique flavor and moisture.

Step 3: Combine the Dry Ingredients

In a separate bowl, whisk together your flour, baking soda, baking powder, and salt. Whisking them upfront helps distribute the leavening agents evenly, which is key for that perfect rise.

Step 4: Cream Butter and Sugar, Then Add Eggs

In a large bowl, beat the softened butter and brown sugar together until the mixture looks light and fluffy – about 1 to 2 minutes with a hand mixer or stand mixer. This step is worth the effort because it traps air right into the batter. Then, add the whole egg, the egg white, and vanilla extract, mixing until everything is smooth and glossy.

Step 5: Bring It All Together

Stir the banana-sourdough mixture into the wet ingredients, then gradually fold in the dry flour mixture using a spatula. Be gentle here — overmixing can lead to a tough bread. You want to stop as soon as the flour disappears into the mix.

Step 6: Bake and Cool

Pour the batter into your prepared loaf pan and smooth the top with a spatula. Bake for 40 to 45 minutes. You’ll know it’s ready when a toothpick poked into the center comes out clean or with just a few moist crumbs clinging on. Once done, use the parchment edges to gently lift the bread out, then transfer it to a wire rack to cool completely before slicing.

How to Serve Sourdough Discard Banana Bread Recipe

Garnishes

I usually keep it simple with a slather of butter or cream cheese to really bring out the flavors. Sometimes, I sprinkle a little cinnamon sugar on top just before baking for a sweet crunch that makes the bread feel extra special. If you’re serving it warm, a drizzle of honey or a smear of nut butter works beautifully too.

Side Dishes

This banana bread pairs wonderfully with a hot cup of coffee or tea. For breakfast, I like to serve it alongside fresh fruit or a simple yogurt parfait — the tang from yogurt complements that sourdough note so nicely.

Creative Ways to Present

For brunch gatherings, I’ve sliced the loaf into thick pieces and arranged them on a rustic wooden board with small bowls of nut butter, jam, and fresh berries on the side. It makes the breakfast table look inviting and gives everyone a chance to customize their slice. You can also toast slices lightly and serve with a scoop of vanilla ice cream for a dreamy dessert twist.

Make Ahead and Storage

Storing Leftovers

After the bread cools, I wrap it tightly in plastic wrap or keep it in an airtight container. It stays perfectly moist at room temperature for up to 3 days — ideal if you plan to enjoy it quickly. For longer freshness, I pop it in the fridge where it can last about a week without drying out.

Freezing

This banana bread freezes like a charm. I usually slice it first, wrap individual pieces in parchment or plastic wrap, then place them in a freezer-safe bag. That way, I can pull out exactly how many slices I want and have a quick breakfast or snack on demand. It freezes well for up to 3 months.

Reheating

To reheat, I recommend popping a slice in the toaster oven or warming it in the oven at 300°F for about 10 minutes. This helps restore the soft texture and brings back that fresh-baked aroma. Avoid microwaving if you can — it sometimes makes the bread rubbery.
