How to Make Sourdough Chocolate Chip Cookies
Making these cookies is easier than you think, and trust me, the results are totally worth it! Follow these steps and you’ll be enjoying fresh, warm cookies in no time.
Start by preparing your butter
Begin by browning the butter. This will give your cookies that deep, nutty flavor that takes them to the next level. Once done, let it cool slightly while you gather the other ingredients.
Here is a full step-by-step guide on how to brown butter.
Mix the dry ingredients
In a bowl, whisk together your plain flour, baking powder, baking soda, and sea salt.
This step is key to ensuring everything is evenly distributed, so take a moment to mix well. The dry ingredients will work together to create that perfect texture we’re going for.
Cream the butter and sugars
In a large mixing bowl, add the browned butter along with the caster sugar, light brown sugar, and dark brown sugar.
Whisk them thoroughly until the mixture turns velvety smooth and irresistibly creamy.
Add the eggs and vanilla
Next, crack in your egg yolks (and the whole egg) and add the vanilla extract (and almond extract if you’re using it).
Mix it all together until it’s smooth. You’ll notice the texture becoming even richer and more luscious, don’t skip this step, it makes all the difference!
Stir in the sourdough discard
Add your sourdough starter discard into the mixture. Mix thoroughly until it blends seamlessly into the mixture.
The discard adds that tangy flavor that makes these cookies extra special. It’s a little extra step that makes them unique!
Combine the wet and dry ingredients
Gradually blend the dry ingredients into the wet mixture, ensuring a smooth and even consistency.
Mix slowly to avoid overworking the dough. You want to stop when the dough just comes together, so it stays soft and chewy.
Fold in the chocolate chunks
Now, for the fun part! Gently fold in the dark chocolate chunks. I love using rough chunks because they create those amazing pockets of gooey chocolate, but chips work just as well.
Mix until the chocolate is thoroughly and uniformly dispersed throughout the dough.
Chill the dough
Though optional, I strongly suggest including this step for the best results. Wrap the dough in plastic wrap and pop it in the fridge for at least 2 hours.

Chilling the dough helps the flavors develop and gives you those perfectly chewy cookies with slightly crisp edges.
Shape and bake the cookies
Preheat your oven to 180°C (350°F). Scoop the dough into balls and place them on a baking sheet lined with parchment paper, giving them enough space to spread out.
Bake for about 15 minutes, or until the edges are golden and the center is still a little soft. Don’t worry, they’ll firm up as they cool.
Let them cool (if you can wait)
Once out of the oven, let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack.
If you can resist, let them cool completely, otherwise, grab one while it’s still warm and enjoy that gooey chocolate!

4 Mistakes to Avoid When Making Sourdough Chocolate Chip Cookies
Skipping the Browning of the Butter
Don’t skip the step of browning the butter. It might seem like an extra step, but it’s essential for bringing out that deep, nutty flavor that makes these cookies stand out.
Just be sure to let it cool slightly before mixing it with the sugars, or else it could affect the texture of your dough.
Overmixing the Dough
It’s tempting to mix the dough until it’s perfectly smooth, but overmixing can lead to dense cookies.
After adding the dry ingredients, mix gently until just combined to avoid overmixing. This will keep your cookies light and chewy, rather than tough and hard.
Not Chilling the Dough
While it’s tempting to bake right away, letting your dough chill for at least 2 hours (or even overnight) makes a huge difference.
Chilling allows the flavors to develop and prevents the cookies from spreading too thin during baking. The result? Thick, chewy cookies with the perfect texture.
Overcrowding the Baking Sheet
If you place your cookie dough too close together on the baking sheet, they won’t have enough space to spread out and bake evenly.
Ensure there is approximately two inches of space between each cookie for even baking.
This will help them spread beautifully and maintain their chewy texture without becoming too flat.

Storing Tips for Sourdough Chocolate Chip Cookies
Airtight Container: Store at room temperature in an airtight container to keep them soft and chewy.
Freeze for Longer Life: Freeze cookies for up to a month in a sealed bag with parchment between layers.
No Fridge: Avoid refrigeration, it’ll make the cookies hard and lose their chewy texture.
Reheat for Freshness: Warm in the oven for 3-5 minutes at 350°F (180°C) to enjoy that fresh-baked feel.
