If you’re anything like me, you probably can’t walk past the cookie jar without sneaking just one more, especially when those cookies are warm, chewy, and packed with melty chocolate.
But the first time I baked sourdough chocolate chip cookies, I wasn’t just chasing nostalgia; I was rescuing extra sourdough discard from the bin and transforming it into something truly magical.
These cookies are my go-to for cosy weekends at home, gifts for friends, and impromptu taste tests that turn into full-on happy dances around the kitchen.
In this article, I’ll share my favourite Sourdough Chocolate Chip Cookies Recipe, one that balances crisp edges, soft centres, subtle tang, and those irresistible chocolate pockets we all crave.
What areSourdough Chocolate Chip Cookies?
Unlike traditional chocolate chip cookies, sourdough chocolate chip cookies use sourdough starter or discard in their dough.
This ingredient isn’t just a clever way to reduce waste, it adds subtle depth, improved texture, and sometimes a hint of tang that makes these cookies more nuanced than your everyday bake.
Many bakers love them because the fermentation process tenderises gluten and helps balance sweetness, resulting in cookies that are chewy, flavorful, and just a little bit special compared to classics.

Step-by-Step Instructions
Prepare the Oven & Tools
Start strong by preheating your oven to 350°F (175°C). This ensures even baking and a perfect cookie texture. Line baking sheets with parchment paper or a silicone mat to prevent sticking and promote golden edges.
Gather essential tools: a large mixing bowl for the wet ingredients, a medium bowl for dry ingredients, a spatula for folding, and a cookie scoop for uniform cookies.
Using a kitchen scale to weigh ingredients like 2 ½ cups (300g) flour and 1 cup (226g) butter guarantees consistency every time.
Proper preparation is the secret to cookies with crisp edges, soft centres, and evenly melted chocolate. Set yourself up for flawless results from the very first step.
Whisk Dry Ingredients
Next, focus on your dry ingredients for a perfect cookie structure. In a medium bowl, combine 2 ½ cups (300g) all-purpose flour, 1 tsp baking soda, and ½ tsp fine sea salt. Whisk thoroughly to distribute the leavening evenly.
This ensures every cookie rises consistently. Lightly sifting the flour can prevent lumps, creating a smoother, tender crumb.
Mixing the dry ingredients separately also avoids overworking the dough when combined with wet ingredients, giving cookies that ideal balance of crispy edges and soft, chewy centres.
Properly prepared dry ingredients set the foundation for perfect sourdough chocolate chip cookies every time, making your baking process effortless and reliably delicious.
Cream Butter and Sugars
Now it’s time to cream the butter and sugars the heart of rich, tender cookies. In a large mixing bowl, beat 1 cup (226g) unsalted butter, softened, with ¾ cup (150g) packed brown sugar and ½ cup (100g) granulated sugar.
Mix on medium speed until light, airy, and fluffy. This aeration is key for soft, chewy centres and slightly crisp edges. Scrape down the sides frequently to ensure uniform blending.
For extra depth, try browning the butter before creaming it, which adds caramelised, nutty undertones that elevate the classic chocolate chip cookie flavour.
Perfectly creamed butter and sugars create the ideal base for your sourdough chocolate chip cookies every single time.
Mix in Wet Ingredients
With your butter and sugars perfectly creamed, it’s time to incorporate the wet ingredients for rich, flavorful dough. Add 1 cup (240g) sourdough starter discard, 2 large eggs, room temperature, and 2 tsp pure vanilla extract to the bowl.
Mix gently on low speed or fold by hand until fully combined avoid overmixing to preserve a soft, tender crumb. The sourdough starter adds subtle depth and complexity, enhancing sweetness without overpowering. Scrape the bowl often to ensure even distribution.
This step transforms simple ingredients into a luxuriously smooth, aromatic dough, the perfect canvas for folding in chocolate chips in the next step, and ultimately crafting sourdough chocolate chip cookies with unparalleled texture and flavour.
Combine Dry + Wet
Now it’s time to bring everything together for the perfect cookie dough. Gradually add your whisked dry ingredients: 2 ½ cups (300g) all-purpose flour, 1 tsp baking soda, ½ tsp salt to the creamed wet mixture of butter, sugars, sourdough discard, eggs, and vanilla.
Mix gently on low speed or fold by hand until just combined. Overmixing can create tough cookies, so stop as soon as the flour disappears. This careful folding ensures soft, chewycentress and crispy edges.
Your dough should be smooth, slightly sticky, and aromatic, ready for the next indulgent step: folding in chocolate chips, which will create pockets of gooey, melty chocolate in every bite.
Fold in Chocolate Chips
This is the moment that makes these cookies irresistible. Gently fold in 2 cups (340g) semi-sweet chocolate chips into your dough, reserving a few to press on top for a bakery-style finish.
Use a spatula to evenly distribute the chocolate without overmixing, preserving the dough’s soft, tender texture and chewy centres.
The chips will melt slightly during baking, creating pockets of rich, gooey chocolate in every bite. Optional enhancements like flaky sea salt or toasted nuts can be added now to elevate flavour and crunch.
Mastering this step guarantees sourdough chocolate chip cookies with a perfect balance: golden edges, soft interiors, and irresistible chocolate throughout.
Chill the Dough
Chilling the dough is a game-changer for perfect sourdough chocolate chip cookies. Cover your prepared dough with plastic wrap and refrigerate for at least 30 minutes, ideally 1–2 hours.
This step allows the butter to firm up, preventing excessive spreading during baking and enhancing chewy, tender centres. The resting period also deepens flavour, letting the 1 cup (240g) sourdough starter discard develop subtle, rich notes.
For even better results, overnight chilling intensifies taste and improves texture. When ready, scoop dough directly from the cold bowl.
This ensures uniform cookies with golden edges and melty chocolate pockets. Chilled dough sets the foundation for flawless, bakery-quality results every time.
Scoop & Bake
It’s time to turn your dough into golden, chewy cookies. Using a cookie scoop or tablespoon, portion out rounded balls of dough, about 2 tablespoons each, onto a lined baking sheet spaced 2 inches apart.
Press a few reserved chocolate chips gently on top for a bakery-style finish. Bake in a preheated 350°F (175°C) oven for 10–12 minutes, until edges are golden, and centres remain soft and slightly underbaked.
This ensures crispy edges with gooey, melty chocolate pockets in every bite. Let cookies cool on the sheet for 5 minutes before transferring to a wire rack.
Proper scooping and baking guarantee consistent, irresistible sourdough chocolate chip cookies every time.
Cool & Enjoy
After baking, let your cookies rest on the sheet for 5 minutes. This allows them to set without breaking apart. Transfer carefully to a wire cooling rack to finish cooling while preserving crispy edges and soft, chewy centres.
The 2 cups (340g) of chocolate chips will remain slightly melty, giving every bite that indulgent, gooey texture. For the best flavour, enjoy cookies warm with a glass of milk, a scoop of ice cream, or your favourite coffee.
Storing a few cookies in an airtight container keeps them fresh for days, while leftovers can be lightly reheated to revive that bakery-fresh warmth.
This final step turns your sourdough chocolate chip cookies into irresistible, unforgettable treats.
