Best Sourdough Discard Chocolate Chip Cookies
This post may contain affiliate links. Please read my disclosure policy to learn more.
These chewy sourdough chocolate chip cookies have crisp edges, gooey centers, and the right hint of tang from sourdough starter discard. They are made with simple ingredients, and plenty of milk chocolate for that nostalgic, classic chocolate chip cookie flavor.
I'm reading your mind. No, chocolate chip cookies are not revolutionary. But having a dependable, crowd-approved sourdough chocolate chip cookies recipe saved in a permanent place? That feels essential.
Especially when your critics live under the same roof.
If you keep a jar of sourdough starter in your fridge like I do, this sourdough chocolate chip cookie recipe is one you will make again and again. Because let’s be honest, most of us are not looking for a cookie that is wildly creative. We are looking for the one that makes everyone reach for “just one more.” That is exactly what these sourdough discard chocolate chip cookies do.
The sourdough starter discard adds a subtle depth that you cannot quite put your finger on at first. It does not make the cookies taste sour. Instead, it balances the sweetness of the milk chocolate and brown sugar, creating that right hint of tang that keeps them from tasting flat. The result is a chewy chocolate chip cookie with crisp edges, gooey centers, and layers of flavor.
Another reason these are the best sourdough chocolate chip cookies is the overnight rest. Letting the cookie dough ferment in the refrigerator gives the flour time to fully hydrate and allows the fermentation process to develop flavor naturally. That slow rest not only creates better texture, but may also make the cookies somewhat easier to digest compared to traditional cookie dough baked immediately.
My family is a huge fan of my sourdough chocolate sandwich cookie recipe and my oatmeal sandwich cookie recipe, but those require a bit more work so this is one that I can whip up much quicker for them.

Ingredients
Sourdough Starter Discard
This recipe uses unfed sourdough starter discard, not active sourdough starter. The hydration starter should be thick, not watery. Too much water content can cause spreading.
Butter
Use unsalted butter at room temperature. Do not use melted butter. Proper creaming gives the best results.
Egg Yolks Only
Using egg yolks instead of a whole egg creates chewy cookies with gooey centers and avoids a cake-like cookie texture.
Milk Chocolate
Milk chocolate keeps these soft and sweet. You can substitute chocolate chunks or dark chocolate chips next time if you prefer less sweetness.
- Ingredients
- Unsalted butter
- White sugar
- Brown sugar
- Egg yolks
- Sourdough starter discard
- Pure vanilla extract
- All purpose flour
- Baking powder
- Baking soda
- Sea salt
- Milk chocolate chips
See recipe card for quantities.
Instructions
Step 1: Cream the Wet Ingredients
In a stand mixer fitted with a paddle attachment, beat unsalted butter, white sugar, and brown sugar on medium speed for 3 to 4 minutes until light and fluffy.
Add egg yolks one at a time, mixing on low speed until combined. Stir in sourdough starter discard and pure vanilla extract.
The mixture should resemble thick cookie batter.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together all purpose flour, baking powder, baking soda, and the amount of salt listed.
Slowly add the dry ingredients to the wet ingredients in three additions, mixing just until combined.
Step 3: Add Chocolate
Fold in milk chocolate chips until evenly distributed.
Step 4: Chill the Dough
Cover the large mixing bowl tightly with plastic wrap and refrigerate for at least 24 hours. This dough ferment step creates the best flavor and improves texture the next day.
Step 5: Shape and Bake
Preheat oven to 350 degrees.
Use a cookie scoop to form cookie dough balls. Place them on a parchment-lined baking sheet, leaving space between each.
Bake 12 to 14 minutes until edges are golden brown but centers still look slightly underdone.
For crisp edges and chewy centers, remove when the bottom of the pan shows light browning.
Let cool on the cookie sheet for 5 minutes, then transfer to a wire rack.
Optional: Add a sprinkle of flaky sea salt while warm.
Storage and Freezing
Store baked cookies in an airtight container for up to 4 days.
To freeze:
Bake from frozen, adding 1 to 2 extra minutes
Roll balls of cookie dough
Place in a freezer-safe bag
Troubleshooting Sourdough Discard Chocolate Chip Cookies
Even the best sourdough discard chocolate chip cookies can go wrong if small details shift. Here’s how to fix the most common issues.
Why did my cookies spread too much?
Possible causes:
• Butter was too soft or partially melted
• Dough was not chilled long enough
• Sourdough starter discard was very runny
• Not enough flour
Fix for next time:
Chill the dough at least 24 hours. Use room temperature butter that is soft but not greasy. If your starter has high water content, reduce it slightly or add 1 to 2 tablespoons of flour.
Why are my cookies dry or crumbly?
Possible causes:
• Too much flour
• Overbaking
• Oven temperature too high
Fix for next time:
Spoon and level your all purpose flour instead of scooping directly from the bag. Pull cookies when centers still look slightly underdone. They finish cooking on the cookie sheet.
Why are my sourdough cookies cakey instead of chewy?
Possible causes:
• Used a whole egg instead of egg yolks
• Too much baking powder
• Not enough chill time
Egg yolks create rich, chewy cookies. Using egg whites or a whole egg can make them more cake-like.
Why do my cookies taste too sour?
Possible causes:
• Very old discard
• Highly acidic starter
• Long fermentation in a warm environment
Fix:
Use discard that is less than a week old and has been stored in the fridge. The dough should ferment in the refrigerator, not at room temperature.
Why didn’t my cookies spread at all?
Possible causes:
• Too much flour
• Dough too cold
• Oven not fully preheated
Let dough sit at room temperature for 10 to 15 minutes before baking next time.
