Sourdough Chocolate Chip Cookies are a simple twist on classic chocolate chip cookies that adds a subtle but delicious change in the flavor of the cookies, while also making them extra soft and chewy. These sourdough discard chocolate chip cookies are a great way to use up extra discard while making a tasty treat!

I am a sourdough lover. My sourdough start is constantly fed and ready to go so I can have fresh sourdough bread, tortillas, english muffins, etc, whenever I feel like it. This also means I've usually got some sourdough discard laying around, which I hate to waste so these Sourdough Discard Chocolate Chip Cookies are the perfect way to use it up!

Ingredients
Ingredient Notes
- Sourdough discard is the by-product of a sourdough starter. It is what you remove from your starter before feeding it fresh water and flour.
- I prefer semi-sweet chocolate, but you can use whatever you prefer. If you’re wanting puddles of chocolate chop up a chocolate bar instead of using chocolate chips. Find the same delicious chocolate puddles in my Brownie Bites.
- Measuring the all-purpose flour correctly is very important. I suggest weighing your flour out. If you want to use a measuring cup, make sure you spoon the flour into the cup and level it off with a knife. Don’t use the cup to scoop directly from the flour.
See the recipe card below for a full list of ingredients and measurements.
Substitutions and Variations
- You can use brown butter instead of regular butter to add even more depth of flavor. I use brown butter in my Brown Butter Cookies.
- Use different types of chocolate chips to add more flavor or to change the flavor of the cookies. White chocolate makes these Raspberry and White Chocolate Chip Cookies extra sweet.
- Mix pecans, walnuts, or almonds into the cookie dough for some added crunch. I use pecans in my Pecan Chocolate Chip Cookies.
- Add cocoa powder to the cookie dough to create Double Chocolate Sourdough Chocolate Chip Cookies. I also use cocoa powder in my Fudgy Brownies.

Expert Baking Tips
- Chill your cookie dough. I know skipping this step is tempting (you want your cookies as quickly as possible and I can’t blame you for that!) but don’t do it! Chilling cookie dough prevents the cookies from overspreading. This can cause them to be thinner, and crispier, and change the overall flavor of the end product.
- Use an oven thermometer. Most ovens run either hot or cold. Using an oven thermometer ensures that you are baking your cookies at the perfect temperature.
- Don’t use cold ingredients. Ensure that all of your cold ingredients are at room temperature before making your cookies. The ingredients will combine much easier and you won’t have chunks of cold butter in your cookie dough, which can lead to greasy cookies.
- Weigh your ingredients. One of the most common baking mistakes that I see is measuring incorrectly, especially with flour. The best way to get accurate measurements every time is to weigh them with a kitchen scale.
- Use a cookie cutter to shape your cookies after baking. If you shake a cookie cutter around the cookies when they are fresh out of the oven they will be perfectly round and more visually appealing.
- Sprinkle the cookies with flaky sea salt before serving. Salt complements chocolate perfectly and will really bring out the flavor.
Recipe FAQ's
The butter was probably too warm when you baked the cookies. This is why I recommend resting the dough in the fridge for 30 minutes before baking.
You sure can! I recommend scooping the cookie dough while it is soft and then placing it in the fridge for up to three days or in the freezer for up to two months.
Room Temperature: The Sourdough Chocolate Chip Cookies can be stored in an airtight container at room temperature for up to 5 days.
Refrigerator: If stored correctly in an airtight container the cookies will last up to 1 week in the fridge.
Freezer: I recommend scooping the cookie dough and freezing it on a baking sheet, then transferring them to an air-tight container. That way you can pull out one or two cookies whenever you’d like them. I leave them sitting out at room temperature for about 30 minutes and then bake them normally. The dough will last up to 2 months.
You can also bake the cookies and then store them in an airtight container in the freezer for up to 2 months.
Sourdough discard is a by-product of sourdough starter. It is what you remove from the sourdough starter before you feed it fresh water and flour. It can be thrown away or it can be used in other recipes to add flavor and moisture.
