Ingredients You’ll Need
- 100 g unsalted butter: Softened for easy blending. If you’re out of unsalted, use salted but reduce the pinch of sea salt to balance flavors.
- 175 g light brown soft sugar: This adds a subtle caramel flavor and helps keep the cookies moist. Can substitute with granulated sugar for a lighter taste.
- 115 g sourdough discard: The star of the show! This adds that delightful tanginess. Ensure it’s at room temperature for flawless mixing.
- 1 medium egg: Provides moisture and binds the ingredients together. For a vegan alternative, use a flax egg (1 tbsp ground flaxseed + 2.5 tbsp water).
- 1 tsp vanilla extract: Enhances the flavor profile. Always go for pure vanilla for a richer taste.
- 250 g plain flour: The base of your cookies. All-purpose flour is perfect here.
- 1 tsp bicarbonate of soda: Helps the cookies rise, ensuring a light and airy texture.
- Pinch of sea salt: Elevates the sweetness of the chocolate and plays well against the sourdough.
- 200 g chocolate chunks: Use your favorite chocolate! Dark, milk, or even white chocolate will work wonders for adding a rich, delightful flavor.
How to Make Sourdough Discard Chocolate Chip Cookies
- Cream the Butter and Sugar: In a mixing bowl, beat together 100 g unsalted butter and 175 g light brown soft sugar until the mixture is light and fluffy.
- Add the Wet Ingredients: Incorporate 1 medium egg, 1 tsp vanilla extract, and 115 g sourdough discard into the mixture. Beat until everything is well blended and smooth.
- Mix the Dry Ingredients: Gradually add 250 g plain flour, 1 tsp bicarbonate of soda, and a pinch of sea salt to the bowl. Stir gently until just combined, being careful not to overmix.
- Add the Chocolate: Fold in 200 g chocolate chunks until they are evenly distributed throughout the dough.
- Portion the Dough: Using a 5 cm cookie scoop (or a heaped tablespoon), portion the dough onto a tray. Leave space between each cookie as they will spread during baking.
- Chill the Dough: This step is crucial! Chill the dough for at least one hour in the freezer for the best texture and flavor.
- Preheat the Oven: Set your oven to 200ºC (or 180ºC if using a fan oven) and prepare two large baking trays by lining them with parchment paper.
- Arrange Cookies: Divide the chilled cookie dough among the trays, ensuring they’re spaced out adequately for spreading.
- Bake: Pop the trays in the oven and bake for 12-14 minutes, or until the edges are golden. Once done, remove them from the oven and allow the cookies to cool completely on the trays.
Storing & Reheating
To keep your Sourdough Discard Chocolate Chip Cookies fresh, store them at room temperature in an airtight container for up to five days. If you’d like them to last longer, pop them in the refrigerator where they can stay for about a week. Want to save some for later? Freeze the cookies in a single layer, then transfer them to a zip-top bag for up to three months. For a quick refresh, simply reheat them in the oven at 170ºC for about 5-7 minutes, and they’ll regain that lovely chewy texture.
Chef’s Helpful Tips
- Avoid overmixing the dough once you add the flour; this helps prevent tough cookies.
- Ensure your butter is at room temperature for the best creaming results—nobody wants clumpy butter in their cookies!
- If the dough feels too soft, chilling is key for getting those perfect cookies.
- Don’t skip the chill time! It not only improves the flavor but gives you that delightful chewy texture.
- Experiment with different types of chocolate or add nuts for extra crunch!
Sourdough Discard Chocolate Chip Cookies are a delicious way to make the most of your baking adventures, turning leftovers into something special. They blend a little bit of sweet with a touch of tang, and once you experience that delicious chew, I’m confident you’ll be coming back for more.

Recipe FAQs
Can I use active sourdough starter instead of discard?
Absolutely! If your sourdough starter is active, just make sure to use it within a few hours after feeding it. This gives your cookies an extra rise.
What if I don’t have chocolate chunks?
No problem! You can use chocolate chips, or even alternate with other mix-ins like dried fruit or nuts to create your own unique flavor profile.
Can I make these cookies gluten-free?
Yes, you can substitute the plain flour with a 1:1 gluten-free baking blend. Ensure that the blend you choose contains xanthan gum or add it separately for elasticity.
How do I know when the cookies are done baking?
Look for the edges to be golden brown while the centers should still look slightly underbaked. They will firm up as they cool, creating that perfect soft center!
