Fall-Spiced Sourdough Chocolate Chip Cookies with Spelt & Oats
Fall Edition — A Year of Sourdough Chocolate Chip Cookies
Long-Fermented or No-Wait — Enjoy These Cozy, Fall-Spiced Sourdough Chocolate Chip Cookies with Fresh-Milled Spelt Flour, Hearty Oats & Sourdough Discard!


Fall is the kind of season that keeps you busy while luring you with the promise of coziness.
Checklists tend to run long, daylight increasingly short. There are so many things to be done (Preserve fall produce! Bake all the cozy things! Holiday season coming up!). And yet, nothing seems quite as promising as the thought of pulling on a pair of thick wool socks, putting up your legs and sipping a steaming cup of something, while watching dusk settle in earlier with each passing day.
These spelt and oat sourdough chocolate chip cookies are a lot like fall. They’re simple and quick to stir together, but you’ll have to wait a minute (or 48 hours) before you can slow down and enjoy a cookie break. It might just be best that way, too. After all, there’s usually a lot going on anyway, so splitting up the cookie making work is probably a blessing in disguise. Not a bad deal, right?
Why You’ll Love This Recipe
To me, sourdough has always been about flavor first. Fermentation naturally elevates flavors and if you combine it with freshly milled flour, you get to taste a richness that far surpasses a white flour, white sugar cookie. Depending on how tangy you like your cookies, you can let the cookie dough ferment in the fridge for up to three days—it’s up to you!
For an extra cozy fall treat, I added a rich blend of warming spices and wholesome oats for a little more toothsome texture. They’ll bake up like a classic chocolate chip cookie—crispy on the outside, tender on the inside.
You can ferment them now, and either bake right away or, in true make-ahead-fall-fashion, stash part of the rolled out cookie dough balls in the freezer for later. That way you’ll never be more than 20 minutes away from a fresh, delicious sourdough cookie in the future.


Tools You May Need
Wire Whisk and Silicone Spatula: These cookies can be made by hand, no appliances needed.
Bowl with a tight fitting lid (optional): Chill the dough in a bowl with a tight-fitting lid or wrap it really well to prevent the cookie dough from absorbing any unwanted fridge odors or flavors.
Cookie scoop (optional): Use a small cookie scoop for portioning out even amounts of fridge-cold dough. (I prefer these freshly milled sourdough cookies on the smaller side, as I find them notably more satisfying than their refined counterparts.)
Ingredients and Substitutions

Whole Grain Spelt Flour Milling flour at home will give your cookies the best, complex aromas and also add a lot of nutrients. It’s the best feeling, walking away from a chocolate chip cookie (or two) and feel like you just had a balanced snack. If you’re not milling at home (yet), store-bought whole grain spelt flour will absolutely work in the meantime!
Sourdough Discard You can use active starter or discard less than 48 hours old for a milder sourdough flavor. Sourdough discard that’s been in the fridge for about a week is still active enough to ferment a batch of cookie dough. We’re not looking for rise, jut for flavor and the benefits of fermented grains.
New to Sourdough? You can learn how to grow your own starter and take good care of it in my Simple Sourdough Starter Series.
Rolled Oats Use old-fashioned rolled oats (not quick cooking or instant). They will soften during their time in the fridge, so smaller oats will just disappear into the batter.
Butter For dairy-free chocolate chip cookies, use a high quality vegan block butter (with a fat content of roughly 80% for the best texture in the finished cookies).
Chocolate Chips I use dark mini (i.e. regular German) chocolate chips and prefer them whenever I make smaller cookies. But really, all chocolate is welcome to cookies! Use your favorite chocolate chips, or any chocolate you have on hand. Chopping a whole chocolate bar is always an option as well.
Fall Spice Mix I put together my own mix of spices for a fall-festive flavor. If you don’t have all of the individual spices on hand, feel free to sub any missing (or polarising) spices with more cinnamon. You could also skip the mix altogether and use 4 teaspoons of your favorite pumpkin pie spice instead.
How to Make Sourdough Chocolate Chip Cookies with Freshly Milled Spelt & Oats




01
Prep and Combine Dry Ingredients
Weigh out whole spelt berries and grind them on the finest setting of your grain mill. Add baking powder, baking soda, spices and salt, and stir until well combined.
02
whisk together wet ingredients
In a medium large bowl, whisk together melted butter, sugar and brown sugar until well mixed. Add the sourdough discard and vanilla extract, and mix until combined. Add the egg and whisk just until fully incorporated.
03
mix in dry ingredients and add chocolate chips
Add the dry ingredients into the wet and stir until there are just a few streaks of flour left. Fold in oats until mostly incorporated, followed by the chocolate chips. Mix gently by hand until everything is just combined.
04
Cover and Ferment
Cover the bowl tightly and refrigerate for at least 2 and up to 72 hours, depending on how sweet or tangy you like your cookies.
05
Scoop and bake
Preheat the oven to 175°C (350°F). Use a cookie scoop to portion out even balls of cookie dough. Roll the dough into smooth balls between your palms and place them on a lined baking sheet.
Bake for 10-15 minutes, until the edges just turn golden brown. Let the cookies cool for one to two minutes on the baking sheet, before sliding the parchment paper onto a cooling rack, to cool completely.


Finding Your Perfect Fermentation Time
Sourdough cookie dough changes as it ferments in the fridge. The starter’s bacteria eat away at the sugars and starches—and that results in different cookies! Here’s an overview, to help you bake the kind of sourdough chocolate chip cookie you like best:
If you’re just getting into sourdough, I think you’ll enjoy these cookies most after 1 day of cold fermenting. They’ll taste like a regular chocolate chip cookie with a little something extra. For anyone used to sourdough flavors outside of a bread, 48 hours ist the sweet spot.

Recipe FAQs

This is such a great recipe! I love all the spices in it and your instructions and explanations for fermenting these cookies are so super helpful. I must try these soon!
Since I could not find mace easily 🙄 I left it out. They were supposed to stay in the fridge for 48 hours, but ended up staying there for about 55. But they are great! Not too sweet, just the right amount of spice without it being overpowering. I will most definitely make these again! Even if mine didn’t turn out as pretty as yours😅 And with the whole grain flour I can even tell myself that they are practically healthy😂
They’re definitely as healthy as it gets 😀
If you can’t get a hold of mace, nutmeg will do, though I’d use a little less.
Thanks for reporting back, I’m glad you like them 🫶🏻🍂
