Frequently Asked Questions

What kind of sourdough starter does this recipe need?

For this recipe, your starter needs to be at a 100% hydration sourdough starter. For more information, read Feeding Your Sourdough Starter.

The sourdough starter does not need to be fed and active, it can be discard.

  • If your starter has been sitting in the fridge for a week and has a lot of hooch (the liquid that the sourdough yeast produces as it consumes) on top, the granola bars will have a more pronounced sourdough tang. 
  • If your starter has been sitting on the counter and was fed yesterday, your granola bars will have a less pronounced sourdough flavor.

Can I use different mix-ins?

You bet! What I used was just what I had in my pantry. Feel free to use any variety of nuts, dried fruit, or seeds you want!

  • Nuts – you need 1/2 of chopped nuts, but you can use pecans, almonds, pistachios, peanuts, walnuts or any other variety.
  • Dried Fruits – Use any combination of raisins, cranberries, dried berries, coconut, apricots, dates, or any other dried fruit you like. You need a total of 1 cup.
  • Seeds – Some great ideas are pepitas, sunflower seeds, hemp seeds, and chia seeds. Use just one, or all of them! You need a total of 1/3 cup.
  • Sweetener – Here I used honey, but you can use an equal amount of maple syrup or brown sugar if you want.

How to store homemade granola bars

  • To store: Store, once cool, in an airtight container on the counter for 3-4 days.
  • To freeze: These also freeze well. Stack them with pieces of parchment paper between each bar, and place in a freezer safe container. They will keep for 3 months.

    I'd never have thought to put quinoa in – very clever!

  2. Do you rinse the quinoa first as you do before cooking it?

  3. Oh, yum, I love that you used maple. And I'm totally using chocolate chips next time!

  4. Another great challenge. Glad you got some peace and quiet! Love the quinoa idea, must try that.

  5. I agree, they are better the next day. What a great idea to use Quinoa – I didn't know it could be used raw.

  6. I loved this month's challenge. Chocolate chips, why didn't I think to use them? Thanks for the inspiration!

  7. Hi Jenni, what a beautiful porch! Your granola bars look delicious. I actually loved the idea of using sourdough for that. Thanks for the lovely comment!

  8. Quinoa, awesome! And even more awesome–getting a moment to thyself. Enjoy that backyard, it is lovely!

  9. These were sooo good, and such a great alternative to the packages with unpronounceable ingredients. I used active starter, but since the batter didn't proof, it didn't really rise. I'd love to use up some of the discarded starter I have saved in the fridge without activating it. Would you recommend this method on these bars?

    1. You bet! I have made these both with freshly fed starter and with starter just out of the fridge, and both turn out great!

  10. Any idea if these would freeze well?

    1. Hi Krista! I have not tried to freeze these yet! I don’t know why it wouldn’t work, though. If you give it a try, let me know how it goes!

  11. Excellent and healthy way to use discard. Make this every few weeks. A handy take-along snack when I’m heading out in a rush. I use dark chocolate chips to make it a bit healthier as I find the fruit and syrup add enough sweetness. Thanks for the recipe!

  12. Made these over the weekend. Awesome!!!!! For us we will cut back on the chocolate chips – a bit too sweet. I had a mixture of dried fruit in the cabinet that I used – cherries, cranberries, figs, prunes and dates. Yummy. Thanks for a fantastic recipe and another way to use up my discard.

  13. I’m always looking for ways to use sour dough discard from my starter and WHO KNEW granola bars were one of these ways?! Well you did of course haha! Fantastic recipe thank you!

    What a great way to use sourdough! And I love the addition of quinoa. Yum!

  15. Hi! I’m excited to try this recipe. I noticed a lot the comments mentioned quinoa, but I’m not seeing quinoa mentioned in the recipe itself unless I’m missing something. Did this recipe used to include quinoa? Thanks!

    1. Hi Katie! Yes, I updated this recipe, and it no longer includes quinoa!
