Introduction
If you’ve ever wondered how to use that jar of sourdough discard sitting in the back of your fridge, you’re not alone. Chocolate Sourdough Discard Cookies are the perfect solution for bakers who hate waste but love indulgence. These cookies are intensely chocolaty, delightfully chewy, and have a slightly tangy finish from the discard that elevates the flavor to gourmet status. If you’re a sourdough baker or chocolate lover (or both!), this is the cookie recipe you never knew you needed but will bake again and again.
Why Make Chocolate Sourdough Discard Cookies?
Let’s start by answering the obvious question: Why should you add sourdough discard to cookies? The answer is surprisingly simple: it adds depth. The tang of sourdough discard balances the sweetness of sugar and enhances the chocolate flavor in a way that regular ingredients can’t match.
When making these chocolate sourdough discard cookies, you’ll also:
- Reduce waste by using your unfed sourdough starter
- Get a unique flavor twist you won’t find in traditional cookie recipes
- Enjoy soft, fudgy cookies with chewy edges and gooey centers
The slight acidity of the discard tenderizes the dough, creating an irresistible texture that makes these cookies stand out. The added bonus? They’re super easy to whip up with pantry staples.
Ingredients Breakdown: What You’ll Need
Before diving into the recipe, let’s take a moment to understand the function of each ingredient:
- Unsalted Butter: Adds richness and soft texture. Using softened butter allows air to be whipped in, which lightens the dough.
- Brown Sugar & Granulated Sugar: The brown sugar adds moisture and chewiness, while granulated sugar provides structure and crisp edges.
- Egg: Acts as a binder and gives the cookies lift.
- Sourdough Discard: The star ingredient. Adds flavor, moisture, and a slight tang.
- Vanilla Extract: Enhances all the other flavors and adds warmth.
- All-Purpose Flour: The structural backbone of the cookies.
- Cocoa Powder: Delivers the rich chocolate flavor. Use high-quality unsweetened cocoa for best results.
- Baking Soda: Helps the cookies rise slightly, giving them a nice spread.
- Salt: Balances the sweetness and boosts flavor.
- Chocolate Chips or Chunks: Add melty chocolate pools. Use semi-sweet or dark chocolate for richness.
- Chopped Nuts (Optional): Provide texture contrast and nutty undertones.

How to Make Chocolate Sourdough Discard Cookies (Step-by-Step)
- Preheat Your Oven: Set it to 350°F (175°C) and line your baking sheet with parchment paper.
- Cream the Butter and Sugars:
In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until it’s light and fluffy. This helps incorporate air, making your cookies lighter in texture. - Add the Wet Ingredients:
Mix in the egg, sourdough discard, and vanilla extract. The mixture may look a little separated due to the discard, but that’s completely normal. - Combine the Dry Ingredients:
In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Make sure they’re well mixed so everything distributes evenly in the dough. - Form the Dough:
Gradually add the dry mixture to the wet mixture, stirring just until combined. Don’t overmix—this can lead to tough cookies. Fold in the chocolate chips and nuts (if using). - Scoop and Space:
Drop tablespoon-sized scoops onto your prepared baking sheet. Leave about 2 inches between each dough ball as they will spread while baking. - Bake:
Bake for 10–12 minutes or until the edges are set but the centers are still slightly soft. - Cool and Serve:
Let the cookies cool on the pan for 5 minutes before transferring them to a wire rack. These cookies are divine when still slightly warm.
Tips for the Best Chocolate Sourdough Discard Cookies
- Use Room Temp Discard: Cold discard can cause the dough to seize and change the texture.
- Chill the Dough (Optional): For thicker cookies with deeper flavor, chill the dough for 30 minutes before baking.
- Don’t Overbake: They may look slightly underdone when you take them out. That’s exactly what you want for soft, chewy centers.
- Customize the Mix-ins: Swap chocolate chips for white chocolate, butterscotch chips, or dried cherries.
- Double the Recipe: These freeze beautifully. Make a double batch and store half in the freezer for instant cookie cravings.
Nutritional Benefits of Adding Sourdough Discard
Believe it or not, sourdough discard has some redeeming health qualities. While it’s not a health food per se, it does offer:
- A natural probiotic base, which might contribute beneficial bacteria
- A lower glycemic index than traditional wheat due to fermentation
- Easier digestion for some who are sensitive to gluten
Of course, this doesn’t turn cookies into health food, but it’s a great excuse to enjoy them with a little less guilt!

Storing and Freezing Instructions
- Store at Room Temp: Keep in an airtight container for up to 5 days.

FAQs: Chocolate Sourdough Discard Cookies
Q1: Can I use active sourdough starter instead of discard?
Yes, but it may affect the texture. Discard (unfed starter) is more neutral and ideal for baking sweets.
Q2: What type of cocoa powder works best?
Use high-quality unsweetened cocoa powder for deep chocolate flavor. Dutch-processed cocoa will make the cookies darker and richer.
Q3: Are these cookies sour?
Not at all! The sourdough discard adds just a hint of tang that enhances the overall flavor profile.
Q4: Can I make this recipe gluten-free?
Yes! Use a 1:1 gluten-free flour blend and make sure your starter is made with gluten-free flour.
Q5: Can I skip the nuts?
Absolutely. They’re optional and can be replaced with more chocolate chips, dried fruit, or left out entirely.
Q6: Why did my cookies spread too much?
It could be due to over-creamed butter or too warm discard. Try chilling the dough before baking.
Q7: Can I add sour cream or yogurt for more moisture?
The sourdough discard provides enough moisture, but a tablespoon of yogurt can make them extra fudgy if desired.
