The Best Sourdough Chocolate Cookies You’ll Ever Try

You’re about to meet the cookie that ruined all other cookies for me: sourdough chocolate cookies. These sourdough chocolate cookies are rich, so fudgy, so ridiculously chewy in the center with perfectly crisp edges, you’ll swear they came straight from a bakery display.

They’re deeply chocolatey thanks to cocoa powder, loaded with melty chocolate, and have that irresistible flavor depth that only sourdough starter discard can give.

Ingredients You’ll Need for Sourdough Chocolate Cookies

  • Unsalted butter: softened so it blends smoothly with the sugars and gives that classic cookie base.
  • Granulated sugar & brown sugar: the combo creates just the right balance of crisp edges and a chewy center.
  • An egg: at room temperature, for structure and richness.
  • Vanilla extract: because a little splash makes chocolate taste even better.
  • Sourdough discard: our secret ingredient! Adds depth of flavor and an extra chewy texture. For this recipe, you don’t need an active or bubbly sourdough starter. Just unfed discard straight from your jar. The key is to use discard that’s less than a few days old so it doesn’t add too much acidity.
  • All-purpose flour: the foundation of the dough.
  • Cocoa powder: natural unsweetened for that deep, rich chocolate flavor.
  • Baking soda & salt: the leavening and balance. Be sure that your baking soda is fresh for proper rise.
  • Chocolate chips (or chunks!): fold in plenty, and save a few extras to press on top before baking for that bakery-style look.

Step-by-Step Instructions

Before we start: These sourdough chocolate cookies need some chill time, at least 3 hours in the fridge (overnight is even better!). Chilling keeps the dough thick and helps the cookies bake up nice and fudgy instead of spreading too thin.

Step 1: Cream the butter and sugars

In a large mixing bowl, beat together the room temperature butter, granulated sugar, and brown sugar until the mixture looks light, fluffy, and dreamy. This should take about 2 – 3 minutes with a hand or stand mixer.

Step 2: Add the wet ingredients

Mix in the egg and vanilla until smooth. Scrape down the sides of the bowl so everything is incorporated, then beat in your sourdough discard. The discard blends right in and gives the cookies that irresistible chewy texture.

Step 3: Mix the dry ingredients

In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Slowly add this to the wet mixture on low speed until a thick, chocolatey dough forms. The dough will be sticky. That’s exactly what we want! Fold in the chocolate chips.

Step 4: Chill the dough

Cover the bowl tightly with plastic wrap and pop it in the refrigerator for at least 3 hours. If you’ve got the patience, chill it overnight. The colder the dough, the thicker and more brownie-like the cookies will bake.

Step 5: Get ready to bake

When you’re ready to bake, take the dough out and let it sit at room temperature for 10 – 15 minutes so it’s easier to scoop. Meanwhile, preheat your oven to 350°F (177°C) and line a cookie sheet with parchment paper or a silicone baking mat.

Step 6: Scoop and shape

Scoop about 2 tablespoons of dough using a medium size cookie scoop (around 40 – 45 grams if you’re weighing). Roll each into a ball, then shape it so it’s slightly taller than wide (think mini cylinders). This trick gives you thick, bakery-style cookies. Place them 2 – 3 inches apart on the prepared baking sheet. Pro tip: the dough is sticky, so keep a towel handy to wipe your hands after shaping a few.

Step 7: Bake

Bake for 11 – 12 minutes, just until the edges look set but the centers are still slightly soft. That’s where the gooey magic happens.

Step 8: Add the finishing touch

Let the cookies rest on the baking sheet for 5 minutes before moving them to a cooling rack. While they’re still warm, press a few extra chocolate chips on top for that melty, bakery-style look. If your cookies spread unevenly, grab a round cookie cutter (or even a large glass) and gently swirl it around the edges to nudge them into perfect circles.

Step 9: Store and enjoy

Once cooled, store the cookies in an airtight container at room temperature for up to a week. Honestly, they’re even better the next day. They are so rich, fudgy, and extra chocolatey. If they last that long, consider yourself stronger than me!

Tips To Make The Most Perfect Sourdough Chocolate Cookies

  • Measure with a scale if you can. Cups are handy, but a kitchen scale gives you accuracy every time and helps keep these sourdough chocolate cookies consistent.
  • Stick with sourdough discard. You don’t need an active, bubbly starter here—just discard that’s a few days old (not too sour or acidic).
  • Give the cookies room to spread. Space the dough balls at least 2 inches apart so they bake up thick and chewy instead of running into each other.
  • Cool on the pan first. Let the cookies rest for about 5 minutes before moving to a rack. They finish setting up on the sheet, giving you that perfect chewy center.

Equipment

Ingredients

  • ½ cup (113g) unsalted butter, softened to room temperature
  • ½ cup (100g) granulated sugar
  • ½ cup (100g) packed light or dark brown sugar
  • 1 large egg, room temperature
  • 1 tsp vanilla extract
  • ¼ cup (60g) sourdough discard (unfed, less than a few days old)
  • ¾ cup (95g) all-purpose flour, spooned & leveled
  • ¾ cup (62g) natural unsweetened cocoa powder
  • 1 tsp baking soda
  • tsp salt
  • 1 cup (180g) semisweet chocolate chips (plus a few extra for topping, optional)

Instructions

  • Before we start: These sourdough double chocolate cookies need some chill time, at least 3 hours in the fridge (overnight is even better!). Chilling keeps the dough thick and helps the cookies bake up extra fudgy instead of spreading too thin.
  • In a large mixing bowl, beat together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2 – 3 minutes with a hand or stand mixer.
  • Mix in the egg and vanilla until smooth. Scrape down the bowl, then beat in the sourdough discard. It blends right in and helps give these cookies their irresistible chewy texture.
  • In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Slowly add the dry mixture to the wet ingredients on low speed until you have a thick, chocolatey dough. It’ll feel sticky, exactly what we want! Fold in the chocolate chips.
  • Cover the bowl tightly and refrigerate for at least 3 hours, or overnight if you can wait. Cold dough = thick, brownie-like cookies.
  • When you’re ready to bake, let the dough sit out for 10 – 15 minutes so it’s easier to scoop. Meanwhile, preheat your oven to 350°F (177°C) and line a baking sheet with parchment paper or a silicone mat.
  • Scoop about 2 tablespoons of dough (40 – 45g each if weighing). Roll into balls, then shape them so they’re slightly taller than wide, like mini cylinders. This helps them stay thick and bakery-style. Place 2–3 inches apart on your baking sheet. (The dough is sticky, keep a towel handy to wipe your hands between batches.)
  • Bake for 11 – 12 minutes, until the edges look set but the centers are still a little soft. That’s where the gooey magic happens.
  • Let the cookies rest on the baking sheet for 5 minutes before transferring to a wire rack. While warm, press a few extra chocolate chips on top for that perfect bakery look. If your cookies spread unevenly, use a round cookie cutter (or even a glass) to gently swirl them back into shape.
  • Once cooled, store in an airtight container at room temperature for up to 1 week. They’re even fudgier the next day if you can resist them that long!

Notes

  • Sourdough discard or active starter: Both work in this recipe! Use whichever you have on hand.
  • Weigh your ingredients: Cups can vary, so a kitchen scale is the best way to make sure your cookies turn out fudgy and thick.
  • Don’t skip the chill time: It makes the difference between thin cookies and bakery-style, brownie-like ones.
  • Sheet choice matters: Use a light-colored baking sheet to prevent the bottoms from over-browning.
  • For extra indulgence: Try mixing in dark chocolate chunks or even a sprinkle of flaky sea salt on top before baking.
Servings: 18 cookies
