What makes this sourdough discard banana bread healthy?
Uses Sourdough Discard
Naturally Sweetened with Maple Syrup
Maple syrup is less processed than white sugar and contains trace minerals like manganese and zinc. It also has a lower glycemic index than refined sugar, which can help with blood sugar balance (in moderation).
Whole Wheat Flour Instead of White Flour
Whole wheat flour is a whole grain, which means it retains more fiber, protein, and nutrients. It helps keep you fuller longer and supports better digestion.
Healthy Fats from Coconut Oil
Sourdough discard is the portion of your sourdough starter that you remove (or “discard”) before feeding it with fresh flour and water. As you refresh your mother starter weekly, you will be creating discard.
Minimal Additives and No Refined Sugar
This recipe skips the preservatives, artificial flavors, and refined sugars found in many commercial baked goods, making it cleaner and more wholesome.
Before we get started...
What is sourdough discard?
Sourdough discard is the portion of your sourdough starter that you remove (or “discard”) before feeding it with fresh flour and water. As you refresh your mother starter weekly, you will be creating discard.
Why do you discard it?
Because a sourdough starter is a living culture of wild yeast and bacteria, you have to feed it regularly to keep it active and healthy. But if you kept adding flour and water without removing any starter, you’d end up with a massive bucket of starter—and waste a lot of flour!
So, before each feeding, you discard a portion, then feed the remaining starter.
What can you do with sourdough discards?
Tons of things! You can use discard in:
- Banana bread
- Pancakes & waffles
- Crackers
- Pizza dough
- Biscuits & muffins
- Even cookies and brownies!
It adds a slight tang, extra depth of flavor, and helps reduce food waste.
How should I store my sourdough discard?
1. Store It in the Fridge (Most Common Way)
- After discarding from your starter, scoop the discard into a clean jar or container.
- Seal it with a lid (not airtight if it’s still a little active) and refrigerate.
- It will last about 1–2 weeks in the fridge.
- You can keep adding to the same container over time!
Tip: Label the jar with a date so you remember how old it is.
Frequently Asked Questions
Can you substitute the flour in this healthy sourdough discard banana bread?
It’s best not to replace the flour in this sourdough discard banana bread, especially if you’re looking for reliable results.
Why You Shouldn’t Swap the Flour:
1. Texture Could Change (A Lot)
All-purpose flour has the perfect balance of protein and starch to make banana bread moist, tender, and well-structured. Swapping it out can lead to:
- A dense or gummy texture (whole wheat, oat, almond)
- A loaf that crumbles too easily (gluten-free or nut flours)
2. Moisture Balance is Delicate
Bananas already add a lot of moisture. Subbing in flours like whole wheat, spelt, or oat can absorb more liquid and make your bread too dry unless you adjust the recipe.
Can you make variations of this sourdough discard banana bread?
Yes, you can add nuts, chocolate chips and berries.
My favorite berries to add
Yes, absolutely—you can totally add berries to sourdough discard banana bread, and it’s delicious! Here’s my favorite berries to add how to do it:
- Blueberries (fresh or frozen)
- Raspberries (fresh or frozen)
Tips for Adding Berries:
- Use Fresh or Frozen
Both work! If using frozen, don’t thaw—add them straight to the batter to avoid excess moisture. - Toss Berries in Flour First
Lightly coat berries with a spoonful of flour before folding them in. This helps prevent them from sinking to the bottom of the loaf. - Fold Gently at the End
Stir them in right before baking to keep the batter light and avoid crushing the berries. - Adjust Sweetness if Needed
Depending on the berries’ tartness, you might want to add a tablespoon or two of extra sugar/honey—totally optional though.
Can you substitute the Maple Syrup for something else?
Yes! I have used honey and it works great as well.
What loaf pan did I use in the video instructions?
The loaf pan I’m using in this recipe is so so good, and I cannot recommend it enough. I’ve had it for 8 years and I have never had anything stuck to it.

This recipe is really good! I did make some changes to the ingredients I had at home. I had almost 1/2 cup of maple syrup but added a tbsp of honey also. I changed the coconut oil to melted unsalted butter. I also baked it for about 50 minutes. But definitely recommend!
Hi Brianna, thanks for sharing those substitutions! I bet it turned out delicious 🙂
No joke the best banana bread I have had in a long time. Not too caky or sweet but still satisfies a sweet tooth. ( I used all purpose flour instead of whole wheat.)
Oh thanks so much Caitlin, Im so glad you are enjoying this recipe! Would you share photos with me next time you make it?
This was super yummy. Moist and full of banana-flavor. I couldn’t even tell it was made from whole wheat flour.
This is SUCH a delicious, simple banana bread with healthy ingredients. It absolutely is scrumptious. It’s easy to use honey or maple syrup or even replace some of the sweetener with molasses for an extra dark color and richer flavor. I used a bit less than 1/2 cup of sweetener the first time I made it and the bread turned out excellent. I also appreciate the format of the recipe because it’s so easy to read quickly. Thanks so much for this fantastic recipe.
Hi Ashley, thanks so much for your message! I am so glad to read your are enjoying it. Please make sure to share photos with me! It is so seeing what you make 🙂
