Bump your banana bread game up with sourdough starter for a crazy light, soft loaf that's bursting with pure banana goodness in every bite. This isn't your regular banana bread – it's got this awesome depth from the starter that makes it way better than ordinary quick bread. I've tried tons of ways to use up my sourdough discard, and this has totally become my go-to fix for both banana bread cravings and sourdough leftovers.

The other day, I gave this to some friends who weren't sure about mixing "sourdough" with banana bread. They changed their minds after just one taste – and wanted the recipe before they left my house.

Key Ingredients

  • Ripe Bananas: You'll need four of them for that rich natural sweetness
  • Sourdough Starter: Works as both a natural lifter and texture booster
  • Butter At Room Temp: Makes for better mixing with the sugars
  • White And Brown Sugar Together: Brings perfect sweetness and moisture balance
  • Eggs Not Cold: Really important for good mixing
  • Real Vanilla Extract: Makes the banana taste even better

Step-By-Step Cooking Guide

Getting The Starter Ready:
Start with sourdough that's not cold - fresh after feeding or discard from your fridge works fine. It should have some bubbles and life to it, but doesn't have to be super active since we're adding baking soda too.
Making The Sweet Base:
Beat the room temp butter with both sugars until it looks fluffy and light. Don't rush this part - it matters for the texture. You want it looking pale and whipped before moving on.
Adding Bananas:
Mix your mashed bananas, eggs, and vanilla into the butter mix. Stop when you still see tiny banana chunks - these make awesome pockets of banana flavor in your bread.
Putting It All Together:
Use your hands to gently mix in flour and sourdough starter. Don't go crazy mixing; stop when everything's just combined. Your batter should be thick but still pourable.

I came up with this when looking for fun ways to use my sourdough discard. What started as just trying something new turned into a family favorite that fits right between quick bread and sourdough baking.

Keeping It Fresh

Your bread will stay good on the counter for 4-5 days if you store it right. Don't stick it in the fridge - just cover it with a clean kitchen towel or pop it in a sealed bag. If you want to keep it longer, wrap it up tight with no air pockets and freeze it for up to 6 months.

Warmth Is Key

All your stuff should be at room temp before you start. Cold eggs or butter can make your bread heavy and uneven. Take everything out about an hour before baking, and make sure your starter isn't cold from the fridge.

Getting The Starter Right

While we're not counting on the starter alone to make the bread rise (that's what the baking soda does), using lively starter makes the texture way better. Discard works fine, but check that it's not super sour or it might throw off the taste.

Ingredients

→ Main Components

01 4 overripe bananas, mashed or cut into chunks
02 1 cup sourdough starter
03 2 cups (250g) plain flour
04 ½ teaspoon table salt
05 ½ teaspoon baking soda
06 ½ cup (113g) softened butter
07 ½ cup (100g) white sugar
08 ½ cup (100g) brown sugar
09 2 large eggs, at room temperature
10 1 tablespoon vanilla extract

Instructions

Step 01

Set oven to 350°F. Coat a 9x5 loaf pan with a quick spray of cooking oil.

Step 02

Toss flour, salt, and baking soda into a medium bowl. Stir them together using a fork. Leave nearby.

Step 03

In a big bowl, blend butter with both sugars on medium-high speed till smooth. This should take 1-2 minutes.

Step 04

Throw in the eggs, vanilla, and bananas. Stir until the bananas look mostly blended with just a tiny bit of lumps left. Scrape the sides if needed.

Step 05

Fold the flour mix and sourdough starter gently into the wet batter by hand.

Step 06

Pour the batter into the oiled pan. Bake for 55-65 minutes. It’s ready when a toothpick comes out with crumbs, no wet batter. Let it cool 10 minutes before slicing.

Notes

  1. An active sourdough starter makes all the difference.
  2. Let all your ingredients sit out to warm up before mixing.
  3. When you add the flour, use a light hand to avoid overmixing.
