Big Cluster Sourdough Discard Granola
By Amanda Paa – Updated May 15, 2025
This sourdough discard granola is easy to make and shatters into giant clusters that filled with oats, nuts, and seeds! A fabulous use for leftover sourdough starter that's absolutely delicious, naturally sweetened with maple syrup, that also adds to its warm flavor. The secret to the clumpy texture is thanks to the binding powers of sourdough discard and flax seeds.

I love finding new ways to cook or bake with sourdough discard, extending its use into something delicious. From super flaky sourdough biscuits to chewy sourdough peanut butter cookies and pumpkin bread, the options with sourdough discard are endless!
When it comes to granola, I’m a chunky, clumpy, big cluster girl. And what better to get that result than sourdough discard, a natural binder that’s a bit sticky and can bond oats, seeds, and nuts together.
Based off my Extra Clumpy Granola, this sourdough discard granola uses maple syrup and coconut sugar for a natural caramelized flavor, along with cinnamon for warmth.
And both walnuts and pepita seeds for extra roasted, toasted nuttiness.
What’s the secret to clumpy granola?
I think you’ll find the texture of this granola to be absolutely perfect, shattering into large clusters while being crisp, yet light. It’s great for snacking, as a cereal, or as a yogurt topper. Instead, I learned from Laura Wright in her “The First Mess Cookbook“ that ground flax seeds are key to the snappy, break apart texture. When the ground flax hits liquid, it creates a coating that clings to the dry ingredients and clumps them together, creating an excellent crisp texture.
How to Make Sourdough Discard Granola:
- Preheat oven to 350 degrees F. Put oats on a baking sheet, and bake for 5-7 minutes, until you can smell a little toasty-ness from the oats. Remove from oven and turn down to 300 degrees F.
- Meanwhile, whisk together sourdough discard, maple syrup, oil, vanilla, and coconut sugar.
- When oats are lightly toasted, add to a bowl with the seeds, nuts, and ground flax. Add cinnamon and salt. Spread granola onto parchment lined baking sheet into even layer so that everything is touching each other.
- Pour wet mixture over dry and stir to fully combine.
- Bake granola for 40 minutes. Remove from oven and LET FULLY COOL before touching.
How Long Does Sourdough Discard Last?
You can keep sourdough discard in your refrigerator for up to 10 days. The discard will be more sour the longer it stays in the fridge. So for something like this granola where I don’t want the sourness to come through, I use discard that is less than 6 days old.
Your discard might accumulate a little liquid on the top while it’s in the fridge, which is called hooch, simply meaning alcohol that is the byproduct of fermentation. You can simple pour the liquid off into garbage, and scrape the very top off, and use the rest as discard.
Best Way to Store Granola So It Stays Crisp:
Store your granola in a glass container with tight seal, or a quart sized ziploc bag. Both ways keep air and moisture out, so that crisp texture is not lost. My preferred method is the ziploc bag because I can keep the granola in big clusters rather than having to break them so they fit into a glass jar.
Yield: 10 servings
Ingredients
- 225 grams rolled oats
- 75 grams sourdough discard that’s less than 6 days old
- 1/4 cup pure maple syrup
- 1/4 cup sunflower oil or grapeseed, canola
- 1/4 cup coconut sugar
- 1 tablespoon pure vanilla extract
- 1 tablespoon whole flax seed ground up (or 2 1/2 tablespoons ground flax seed)
- 1/2 teaspoon fine salt
- 2 1/2 teaspoons ground cinnamon
- 75 grams raw walnuts or almonds
- 75 grams raw pepita seeds
Equipment
Instructions
- Preheat oven to 350 degrees F.
- Put oats on a baking sheet, and bake for 5-7 minutes, until you can smell a little toasty-ness from the oats. Remove from oven and turn it down to 300 degrees F.
- Whisk together sourdough discard, maple syrup, oil, vanilla, and coconut sugar so that it is smooth and homogenous.
- Add seeds, nuts, and ground flax to a large bowl. Then add cinnamon, salt, and your toasted oats.
- Pour wet mixture onto the dry mixture and stir until everything is fully coated. Spread granola onto parchment lined baking sheet into even layer so that everything is touching each other.
- Bake granola for 40 minutes. It will still be a tiny bit moist, but will dry as it cools. Trust this. :)
- Remove from oven and LET FULLY COOL before touching and breaking into clumps.

Can I add dried fruit (raisins and crasins) to the granola mix? If so would you recommend I add the dried fruit in the beginning and bake together or add after baking?
Amanda Paa
May 8, 2025
I would add after baking so they don’t dry out in the oven!

Who knew another great option for Sourdough discard and absolutely delicious! Love that it isn’t too sweet. I didn’t modify at all – except that I cooked as one large piece and cut into squares while still warm.

So glad you enjoyed it, Kim!

This granola recipe is INCREDIBLE! I subbed in coconut oil and also added 1/4 cup collagen powder. I just had to add a tiny bit more oil to keep it moist enough, but it turned out great! I do have a question—how long is this granola good for? Does it matter whether I store it in an airtight container on my counter or in the fridge?

This is the best discard granola recipe I’ve used. Often I will add rice Krspies from another recipe to help ulk it up. I am enjoying these recipes and Amanda’s warm engaging personality. Peace.

Hi Amanda. What could I substitute for the flax seed?
Amanda Paa
August 2, 2024
hello! the flax seed is what makes this granola cluster and clumpy. you could maybe try ground chia seed for the same result.
Jana
February 26, 2025
I replaced the flax with chia seeds and it worked beautifully! 1 tbsp.

Hi
Excited to try this! How many servings does this recipe make?
Amanda Paa

Hi! Hard to say since it depends how you define a serving of granola. There’s two of us in the house and I make it often.

This granola is delicious! I subbed pecans for the walnuts and added some chia seeds and unsweetened coconut. It was so good and crunchy. We eat it over our homemade yogurt.
Amanda Paa

Yay, so glad to hear that! Also, homemade yogurt sounds amazing.

The best! I’ve made it twice in 2 weeks and it will now be a weekly staple. I made it with pecans and pumpkin seeds and subbed honey for the maple syrup. Delicious!!!
Amanda Paa

yay, so glad you enjoyed it! i love making it with pecans, too.

This granola is scrumptious! I made a few changes as I did not have coconut sugar so I used brown sugar. I subbed pecans for walnuts. I add a few dried cherries the last ten minutes because I live in MI cherry country. My husband stated it was the best granola I’ve ever made. I have to agree. This recipe is a keeper.
Amanda Paa
April 23, 2024
Yay, so glad you enjoyed it! And so jealous you live in MI cherry country! I have been to Traverse City many times; it is one of my favorite places.

Great recipe! I have made this four or five times and it is always delicious. I stick pretty close to original recipe, subbing pecans for walnuts, just personal preference, and brown sugar for the coconut sugar, because it’s what I have on hand. So delicious! Thanks for a great recipe Amanda!
Amanda Paa
February 28, 2024

Great recipe, I swap out the canola oil for olive oil and add shredded coconut. I have even added dried cranberries etc. (and they don’t burn as long as I soak them in hot water for a bit first).Just the right sweetness and love the clusters.
Amanda Paa
November 18, 2023
sounds great with the coconut and cranberries!
Lisa
October 22, 2023
I can’t wait to try this. Great way to use my discard. If I don’t add nut do I just increase the oats by the same volume? Thank you!
Amanda Paa
October 22, 2023
Hi Lisa! If you don’t do nuts, replace with equal amount of pepita and/or sunflower seeds. Oats would soak up too much of the liquid in place of nuts.

A-MAZE-ING !! I’ve been making my own granola for years, but have never been able to get the clusters, so it’s always really been more like toasted muesli. This recipe is an absolute game changer! I’m quite new to sourdough dough baking, and have yet to master bread making, so it feels very satisfying to have a foolproof recipe for my starter. I used flaked almonds, sunflower seeds and flaked coconut and I don’t have any flax seeds, but the result was still fantastic. I’ve already made it 3 times, slowly lowering the (brown) sugar content as my first batch was a wee bit sweet. The maple syrup and cinnamon add such depth of flavour. Highly recommended 👌

Best granola ever! This is my favorite way to use up my discard! I used coconut oil instead of veg oil and I like to mix up the nuts I use. Also I’ve added a couple tablespoons of cocoa powder and it was also delicious!!!
Amanda Paa
June 5, 2023
Oh, so glad to hear! And I cannot wait to try it with cocoa powder – great idea.

Looks good! I don’t have coconut sugar, could I add more maple syrup instead?
Amanda Paa
April 29, 2023
Hi! The granola will be too wet if you use all maple syrup. You could use brown sugar instead of coconut sugar though!

Great texture and flavor. Easy to customize the size of pieces for whatever you want to do with your granola (mix smaller bits into yogurt or grab bigger chunks for a snack). I added a bit of coconut flakes and the kitchen smelled great!
Amanda Paa
December 31, 2022
So glad you liked the recipe, Brian! Love the idea of adding a little coconut.

I’ve been on the hunt for a good granola recipe! Can’t wait to try it!
(I occasionally feed my discard a little bit of flour in fridge so that I can keep it for longer than a week!)
Kaitlin
October 19, 2022
I have made this recipe several times now and it is the perfect granola recipe in my opinion! I like that it is so low maintenance – just stick it in the oven for 40 min and don’t have to worry about stirring it (although I did forget to turn the oven down to 300 one time and sadly burnt it to a crisp). It’s not too sweet and you can easily substitute (I used pecans instead of pepitas) and added chia and hemp seeds. It’s my favorite way to use discard and everyone who has had this recipe loves it. Thanks!
Amanda Paa
October 20, 2022
Love hearing that, Kaitlin! I like using pecans too sometimes, or cashews!

Made a batch of this for a road trip snack. (Subbed turbinado sugar for the coconut sugar.) I’m watching my BIL, who would tell you he doesn’t like sourdough, scarf it down as I type this. (What he doesn’t know won’t hurt him!) I consider this one a win! 😁

It was another super easy recipe to use my sourdough discard! I didn’t put pepita seeds in the mix since my daughter isn’t a big fan. According to my family “Your granola has a crack quality to it. Can’t stop eating it!” I think I will add coconut chips to next batch, maybe reduce sugar add some dry fruit.
10 out of 10 Would recommend!
Amanda Paa
March 21, 2022
So glad the whole family is enjoying it! I bet coconut chips would be delicious in it.
