Equipment

• 9×5-inch loaf pan
• Mixing bowls
• Whisk
• Rubber spatula
• Cooling rack
• Parchment paper (optional)

Instructions

Step 1: Prepare the Oven

Preheat your oven to 350°F (175°C).

Grease a 9×5-inch loaf pan or line it with parchment paper for easy removal.

Step 2: Mix the Wet Ingredients

In a large mixing bowl, whisk together:

• Mashed bananas
• Melted butter
• Brown sugar
• Eggs
• Vanilla extract
• Sourdough discard

Whisk until smooth and well combined.

Step 3: Add the Dry Ingredients

Add:

• All-purpose flour
• Baking soda
• Baking powder
• Salt
• Cinnamon (if using)

Fold everything together gently with a spatula until no dry streaks remain.

Do not overmix.

If using chocolate chips or nuts, gently fold them into the batter.

Step 4: Fill the Pan

Pour the batter into the prepared loaf pan.

Smooth the top with a spatula.

If desired, top with a halved banana, extra chocolate chips, chopped nuts, or a sprinkle of coarse sugar.

Step 5: Bake

Bake for 55–65 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

If the top browns too quickly, loosely cover the loaf with aluminum foil during the final 15 minutes of baking.

Step 6: Cool

Let the banana bread cool in the pan for 10–15 minutes.

Transfer it to a wire rack and cool completely before slicing.

Expert Tips

• Use very ripe bananas with lots of brown spots for the sweetest flavor.
• Room-temperature eggs help create a smoother batter.
• Avoid overmixing to keep the bread soft and tender.
• Measure flour accurately by spooning it into the measuring cup and leveling it off.
• Let the loaf cool completely for cleaner slices and the best texture.

Storage

Store the cooled banana bread in an airtight container at room temperature for up to 4 days.

Refrigerate for up to 1 week for extended freshness.

To freeze, wrap the loaf or individual slices tightly in plastic wrap and aluminum foil, then place them in a freezer-safe bag. Freeze for up to 3 months. Thaw at room temperature or warm slices in the toaster.

Frequently Asked Questions

Can I use active sourdough starter instead of discard?

Yes! Both active starter and sourdough discard work well in this recipe. Since the bread relies on baking soda and baking powder for leavening, either option produces excellent results.

Does the bread taste sour?

No. The sourdough discard adds depth of flavor and helps create a moist texture, but the sweet bananas remain the dominant flavor.

Can I make muffins instead?

Absolutely. Divide the batter among lined muffin cups and bake at 350°F (175°C) for 18–24 minutes, or until a toothpick inserted into the center comes out clean.

Can I make this recipe dairy-free?

Yes. Substitute the butter with melted coconut oil or a neutral vegetable oil for a dairy-free version.
