Soft Sourdough Chocolate Chip Cookies
If you keep a jar of sourdough discard in the fridge, these sourdough chocolate chip cookies are such a good way to use it. They bake up soft in the centre with crisp edges, chewy middles and melty chocolate throughout. The discard adds a lovely depth without making them taste sour, and the dough is very forgiving.

Sourdough discard cookies
Sourdough discard adds moisture, flavour and a little acidity to the dough. That acidity helps the baking soda do its job and improves the texture, giving then a really soft centre. Using discard in cookies is also a handy way to reduce waste, especially if you bake bread often or refresh your starter more than once a week.
If you are still building your starter or want to learn more about how it, see my sourdough starter guides, or my collection of sourdough discard recipes.

I am so happy to find this recipe. These cookies are so delicious. I reduce the brown sugar to 80g and white sugar to 80g too. Besides I added more dark chocolate and walnuts. Thank you very much.
Trying these for the first time. Them seem buttery and delicious! I am currently chilling the dough. As I was baking I read the note….why was the original recipe shifted? Were there problems with the combination or is it more of a suggestion that we could add more starter and flour to get a different consistency?
Heya adding more flour and starter made a more cake-like cookie and I prefer a chewier one, so I lessened them 🙂 but other readers liked the previous version so I kept both.
I made these dairy free using olivani instead of butter and adding raisins instead of chocolate. The texture was nice and the kids liked them.
Would there be much of a difference if I used bread flour rather than all-purpose flour for this? I bake a lot of bread now (thanks to your other great recipes) so only have bread flour in the cupboard.
I think that will be fine! 🙂 thank you!
I used bread flour and they turned out great!
These are so delicious and easy to make,
I made these on the weekend, chilling the dough overnight (until around lunch time) and made 24 delicious cookies and froze 8 uncooked. Loved them
I put the dough in gladwrap and formed a cylinder, then sliced it for baking when chilled down. Apart from the fact I overcooked them a bit, they came out a smash hit with the Grandies and hubby.
Ooh that’s great to know they work as slice and bake cookies too! Thanks for letting me know! 😀
Can I add instant oat?
Hey Melinda, I have not tried that before so I can’t tell you if that will work well or not
Thanks for the recipe I’m about to make them but I’m not sure about the discard.
Should I use an active starter discard or one from the refrigerator?
A refrigerated discard works well 🙂
