The Ultimate Sourdough Chocolate Chip Cookie

The Ultimate Sourdough Chocolate Chip Cookie

Back to blog

I’ll be honest—most sourdough cookies I’ve tested over the years have been a letdown. The flavor was usually good, but the texture almost always leaned too cakey. And there’s a reason for that. Sourdough discard adds moisture, acidity, and structure, which can easily push cookies into cake territory if the balance is even slightly off. I’ve tossed more test batches than I care to admit while dialing in the variables that matter most: fat, sugar ratios, protein, and hydration. After a lot of testing (and a little sourdough science), I finally cracked it. This is the cookie I’ve been working toward—the Ultimate


Sourdough Chocolate Chip Cookie
, with crisp edges, a soft, chewy center, and incredible flavor in every bite.

Why This Recipe Works

1. Browned Salted Butter = Flavor + Structure

Browning the salted butter removes excess water while developing deep, nutty flavor. Less water means less steam in the oven, which helps prevent a cakey texture and encourages chewy edges with rich caramel notes.

2. The Right Sugar Balance for Chew

An even split of white sugar and light brown sugar gives you the best of both worlds. White sugar helps the cookies spread and lightly crisp, while brown sugar adds moisture and chew thanks to its molasses content.

3. Egg Yolks Only = Tender, Not Cakey

Using egg yolks instead of whole eggs adds fat and richness without extra water or protein from the whites. This keeps the cookies dense and chewy rather than puffy or cake-like.

4. Sourdough Discard Used with Intention

Sourdough discard brings depth of flavor, gentle acidity, and hydration. In this recipe, those elements are carefully balanced with fat and sugar so the discard enhances the cookie without overwhelming the texture.

5. A Controlled Leavening System

A small, intentional amount of baking soda and baking powder provides just enough lift for a soft interior—without over-aerating the dough. The result is structure and chew, not fluff.

Let’s Bake

Now that you know why this recipe works, it’s time to bake. This dough comes together easily, uses sourdough discard with intention, and delivers the chewy, bakery-style texture that’s so hard to achieve with sourdough cookies. Take your time with the browned butter, don’t rush the chilling, and trust the process—you’re about to make the cookie you’ll come back to again and again.

The Ultimate Sourdough Chocolate Chip Cookies

Makes approximately 4 dozen cookies

Ingredients

  • 226 g (1 cup) salted butter, browned
  • 185 g white sugar
  • 185 g light brown sugar
  • 200 g (¾ cup) sourdough discard
  • 2 large egg yolks (about 40 g total)
  • 8 g (2 tsp) vanilla extract
  • 355 g (2½ cups) all-purpose flour
  • 6 g (1 tsp) baking soda
  • 4 g (1 tsp) baking powder
  • 9 g (1½ tsp) salt
  • 350 g (about 1½ cups) chocolate chips

Instructions

1. Brown the Butter

Place the salted butter in a light-colored skillet over medium heat. Melt completely, then continue cooking, stirring often, until the butter foams and golden brown bits form on the bottom of the pan and the aroma turns nutty.

Immediately transfer the butter—including all the browned bits—to a large mixing bowl. Let cool until warm but not hot.

2. Mix the Wet Ingredients

Add both sugars to the browned butter and stir until smooth and glossy.

Mix in the egg yolks, vanilla extract, and sourdough discard until fully incorporated and cohesive.

3. Combine the Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, baking powder, and salt until evenly mixed.

4. Make the Dough

Add the dry ingredients to the wet mixture in two additions, mixing gently just until no dry flour remains.

Fold in the chocolate chips until evenly distributed.

5. Portion & Chill

Scoop the dough into 50–55 g portions (about 2½–3 tablespoons each) to yield approximately 48 cookies.

Roll lightly into balls and refrigerate for at least 2 hours—overnight is ideal for best texture and flavor.

6. Bake

Preheat the oven to 375°F (190°C).

Place 5–6 chilled dough balls on a parchment-lined baking sheet, spacing well apart.

Bake for 11–13 minutes, until the edges are lightly golden and the centers look just set.

7. Cool & Enjoy

Let the cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool—or enjoy warm while the chocolate is still soft and melty.

Optional: Sprinkle lightly with flaky sea salt while warm for a sweet-salty finish.

Baker’s Tip

For perfectly round cookies, gently nudge the edges into shape with two spoons immediately after baking, while the cookies are still soft.
