Sourdough granola bars are the perfect snack. They are easy to pack around and full of sustaining energy. They are a delicious breakfast-on-the-go, school lunch treat or a homemade energy bar. Best of all, they can be made gluten free, sugar free or vegan!
Sourdough Options
I like to preferment all of my grains. However, the sourdough starter in this recipe is only a suggestion. The recipe can also be made with yogurt or buttermilk to soak and ferment the oatmeal.
Here’s why these granola bars are better because of a little fermentation.
- Fermentation adds a delicious sourdough flavour to these granola bars.
- Soaked and fermented grains are easier digest, so this granola bar won’t leave you feeling sluggish from the carb overload.
- Pre-fermentation also eliminates the need for additional flour or sweetener. The lactic bacteria will break down the rolled oats before baking.
Granola Bar Flavours
The best part about homemade baked goods is that they are a delicious way to experiment with flavour. Sourdough granola bars are perfect for so many flavour options. Here are a few of my favourites:
- Blueberry Almond: This classic granola bar is perfect for breakfasts on the go. Use 1/2 cup of almonds, 1/4 cup of dried blueberries and 1/4 cup of shredded coconut.
- Salty Peanut: Use 1 cup of salty peanuts for a salty (not sweet) granola bar. Or use only 1/2 cup of peanuts with 1/2 cup of chocolate chips.
- Immune Boosting: This school-friendly and beautiful granola bar is packed full of zinc, iron and antioxidants. Use a 1/2 cup of goji berries and 1/2 cup of pumpkin seeds.
- Chocolate Pecan: Turn your granola bars into a sweet treat by adding 1/2 cup of chopped pecans and 1/2 cup of dark chocolate chips.
- Tropical Punch: This granola bar combines the sweetness of tropical fruit with high protein cashews for a healthy energy bar that will help you go the distance. Use 1/2 cup of mixed tropical fruit (mango, pineapple and papaya) with 1/4 cup of cashews and 1/4 cup of shredded coconut.

- Cook Time: 50 minutes
- Total Time: 1 hour 5 minutes
- Yield: 12 bars 1x
- Category: Snack
- Method: Sourdough
- Cuisine: Healthy
Ingredients
- 1 1/2 cups of rolled oats (quick or regular)
- 1/2 cup sourdough starter (see notes for yogurt alternative)
- 2 eggs (see notes for vegan flax eggs option)
- 1/4 cup ground dates
- 1 tsp vanilla
- 1/2 tsp salt
- 1 cup mixed nuts, seeds and dried fruit
Instructions
- Mix rolled oats and the sourdough starter in a glass bowl. It will be quite dry. However, cover and leave it to soak or ferment for at least 30 minutes and up to 12 hours.
- Beat in the eggs, ground dates, vanilla and salt.
- Mix in 1 cup of added nuts, seeds, dried fruit or chocolate chips. See the section above for 5 delicious flavour options.
- Grease a 9″ x 9″ baking pan (or other 10 cup baking pan). Spread the granola bar mixture in the pan, and press so that it is firmly packed into the bottom of the pan.
- Bake at 300 F (150 C) for 50-60 min, until firm and browning around the edges.
- Remove from the oven and slice right away. Then allow the granola bars to cool before removing them from the pan.
Notes
- Though the recipe is written for a sourdough starter, you could also use a gluten free sourdough starter or replace the sourdough starter with yogurt or buttermilk. It will be a bit more liquidy, but the oats will absorb the extra liquid and result in a softer granola bar.
- The eggs in this recipe are used as a binder and are mostly necessary for gluten free granola bars. However, flax is a really great binder as well. To replace the eggs with flax, use 2 tbsp of ground flax mixed in a 1/4 cup of water. Leave it to sit and gel for 5 minutes, then stir into the granola bars.
- Date sugar
(affiliate link) is my usual sweetener of choice. It is high in fiber, vitamins and minerals. However, it is not very sweet. To make a sweeter granola bar replace the ground dates with brown sugar, rice syrup or honey.

Hello
How about Kefir milk for the starter?
Yes! I’ve made this with milk kefir and sourdough starter. They both worked great.
Hi Emillie, wow great recipe! Is it also the case that the sourdough starter helps to keep the bars good for a longer time than without? Would you happen to know how long after preparing them they can still be eaten? Thanks!
Glad you like them! Unfortunately, sourdough baked goods can still go off. If you want to keep them for more than a few days, then either put them in the fridge or freezer. 🙂
Ok, good to know, thanks for your reply! 🙂
I made the blueberry- delish! Does this have to be active starter or can it be discard?
Discard is fine! Just don’t use discard that’s more than a few weeks old as it won’t be very active anymore. 🙂
Hi! I’m so excited to try an oil-free granola recipe.
Do you think I can use a chia egg instead flax?
Thanks!
I haven’t tried a chia egg, but I don’t see why not? It will still be tasty even if it’s a bit crumbly. 🙂
Hi! Could this be used to just make granola instead of bars?
Yes! Or you could follow my fermented granola recipe using sourdough discard as your culture: https://www.fermentingforfoodies.com/fermented-granola/
What are ground dates?
It’s sometimes called date sugar. It’s not the same as date paste (which is moist). It’s made from dried dates is about the consistency of ground nuts.
Thank you, really pleased with these. I used date paste and it worked fine. I really like the fact that there is a sweetness there, but they are not overly sweet. Ihave you ever included peanut butter?

I haven’t tried peanut butter because we usually have these as school snacks… and there’s the issue of allergies at school. However, it should work it will probably remain a bit sticky. Not a bad thing, just different. Enjoy!
I used Psyllium instead of eggs and it worked amazing! I also added some dark chocolate chips. Thank you for this recipe!!
Thanks for sharing! Glad to know that psyllium will work as an egg replacement in this recipe.
So excited to try this ,along with all the extra great ideas .I use a lot of chai so that’s going in !
Getting ready to try these awesome sounding bars! I have never made anything with sourdough starter before. I have some from a friend and it is ready.
When you measure it, is it measured when all bubbly or do you stir it before you measure it?
Also, what can be used in place of dates for a bit of sweetness?
Great question! I stir my sourdough starter before measuring. 🙂 And if you don’t mind sugar, you could replace the dates with brown sugar, honey or maple syrup. Enjoy!
I made them – so good! I ended up using a mashed banana for sweetness and added cinnamon, ginger and nutmeg. Thanks for the recipe.

What a great idea!
Wondering how soaked quinoa might work for part of the oats… anyone tried it?
I haven’t tried it. However, there isn’t enough liquid in the granola bars to fully hydrate the quinoa, so I recommend using sprouted quinoa instead. That probably would work!
