Using Up Sourdough Discard

This banana bread is a simple way to use sourdough discard – which is particularly good if you’re going through the process of establishing a sourdough starter.

You can use sourdough discard in this recipe – but active, fed sourdough starter is perfectly fine too!

Just use whatever you have on hand!

And if you love this sourdough banana bread, why not try this sourdough zucchini bread or sourdough discard pumpkin spice bread – they have a very similar style.

How To Make Sourdough Banana Bread

Making sourdough discard banana bread is really easy. You don’t need any fancy equipment and you can mix it all together in one bowl!

The secret to this banana bread being so delicious is the golden syrup glaze on top! It is out of this world! If you’ve never used golden syrup before, you can read up about it here.

Here’s how to make easy sourdough discard banana bread:

  1. Mash the overripe bananas with the back of a fork until they form a puree (a few lumps is fine).
  2. Beat the egg and vanilla together and add to the bananas.
  3. Melt the butter on a low heat and add that to the banana and egg mixture.
  4. Then stir through the sourdough starter until well combined.
  5. Next mix all the dry ingredients together until well combined.
  6. Add the dry ingredients to the wet ingredients and stir until just combined (do not over mix).
  7. Pour the batter into a buttered loaf tin.
  8. Bake at 180C for around 1 hour – or until a skewer comes out of the bread clean.
  9. Glaze while still in the tin.
  10. Allow to cool for 30 minutes before removing from tin.

Tips & Tricks

While this recipe is super simple, there are few things you can do to ensure you get banana bread success!

  • Always use overripe bananas! They need to be brown and a bit squishy. These brown bananas add sweetness and texture to your bread. Do not use fresh, yellow bananas straight from the store.

    A little tip – always keep a stash of brown bananas in the freezer – they are great for emergency banana bread making! Just leave them out for 10 minutes to soften before you mash them up!
  • Be careful not to over mix the ingredients once you’ve added the wet and dry together. Just like sourdough muffins, over mixing can result in tough bread.
  • If you feel that the top of the loaf is browning too quickly, carefully place a sheet of tin foil over the top. This will allow the banana bread to continue cooking, without burning the top of your bread.

Which Loaf Pan To Use?

I have baked this banana bread in a 1 litre loaf pan. It is a great size and makes a nicely proportioned loaf. This loaf will also fit into a 1 pound USA Pan which measures 9″ x 5″.

The pan I’ve used is this Jamie Oliver Loaf Pan – mine is a different color to the one I’ve linked to, but they are the same pan.

I also like that this pan shields the top a little so it doesn’t burn in the oven (also see my tips above for ensuring your loaf doesn’t burn).

If you wanted to make a larger loaf, you could double the quantities in the recipe and make a larger loaf with larger slices.

What Can I Add to Sourdough Banana Bread?

While this sourdough discard banana bread is amazing just as it is, there’s always room for improvement, right?

Add your extras to the dry ingredients before you mix in the wet ingredients to ensure they are evenly distributed.

Here are a few suggestions on things you can add to take your sourdough banana bread to the next level!

  • Roasted and chopped nuts – the easiest way is to purchase your nuts already roasted, but if they’re raw, toast them lightly in a heated pan before adding.

    You could add up to 150g of chopped walnuts, almonds, hazelnuts, pecans or macadamia nuts. I prefer them in the mixture as they don’t burn on the top this way. If you love macadamia nuts, try this sourdough Hawaiian banana bread!
  • Chocolate – bananas and chocolate are sooo good together! Add up to 100g of chocolate chips or your favorite chocolate chopped. White, milk or dark all work well! Or go all out and make this double chocolate sourdough banana bread!
  • Butterscotch or Peanut Butter Chips – these flavors both team up so well with bananas! Add up to 150g of these for a little flavor twist!
  • Pumpkin – Give your sourdough banana bread some serious fall vibes with this sourdough pumpkin banana bread recipe.

    I’ve made this delicious banana bread so many times. My husband and I both love it so much that he begs me for it. Sometimes I may or may not barter making the bread for him doing chores!

    1. Kate Freebairn says:

      Haha I LOVE This!!!! I’m so happy that you love the recipe … and so does your husband! Barter away 😉 xo

  2. Belinda says:

    I’m new to sourdough. My bread came out dense and flat. Followed the recipe. What did i do wrong? Was i meant to bulk ferment?
    Thank you
    Belinds

    1. Kate Freebairn says:

      This one doesn’t need to be bulk fermented no. I would check your baking powder and make sure it’s fresh, that’s one of the most common reason for this recipe coming out flat 🙂

  3. Martha says:

    What are the ingredients for “golden syrup”?

    1. Kate Freebairn says:

      Golden syrup is an inverted sugar syrup and is a by product of refining sugar cane into sugar. You can generally buy it at the grocery store (it’s an Australian staple).

  4. Jeremy says:

    Does maple syrup work? Thanks, looks great just put mine the oven!

    1. Kate Freebairn says:

      Yes you could use maple syrup instead of golden syrup, you just won’t get the really sticky, glossy shine on the top 🙂

    I have tried a few banana bread, recipes and this one with sourdough discard is by far the best. I made it in the morning before church, after church with in about a couple hours my husband had eaten half of it. He said this is definitely a keeper.

  6. Audrey says:

    I’m making this in a few days. Is the weight for the banana with or without the peel?

    1. Kate Freebairn says:

      Without peel 🙂

  7. Melissa Pidal says:

    I love this recipe. I do skip the golden syrup wash. I also add 1/2 tsp of cinnamon and roughly the same amount of freshly grated Nutmeg.
