Chewy Sourdough Chocolate Chip Cookies

So you’ve got some leftover sourdough starter hanging out in the back of your fridge, looking sad and neglected, right? You could feed it like a responsible baker… or you could turn it into chewy sourdough chocolate chip cookies and live your best life. Honestly, feeding a starter doesn’t taste nearly as good as biting into a warm, gooey cookie, so I know which option I’m choosing.

Why This Recipe is Awesome

  • No waste, all taste. Finally, a way to use up that sourdough discard without feeling like you’re tossing money (and carbs) in the trash.
  • They’re next-level chewy. Thanks to the starter, you get that dreamy, bakery-style texture—crispy edges, soft middles, slightly tangy bite.
  • Tang + chocolate = love story. The slight sourdough tang actually makes the chocolate flavor pop. It’s like a rom-com where the quirky characters finally realize they’re perfect for each other.
  • It’s idiot-proof. Seriously, even I didn’t mess these up, and I’ve been known to forget the sugar in cookie dough.
  • They age like fine wine. These cookies stay soft and chewy for days (if you can keep them around that long).

Ingredients You’ll Need

  • Unsalted butter (1 cup, softened): Butter = flavor. Don’t argue with me on this.
  • Brown sugar (1 cup, packed): Adds that caramel-y chewiness. Essential.
  • Granulated sugar (½ cup): For balance, because life needs a little sweetness.
  • Egg (1 large): The glue that keeps it all together.
  • Vanilla extract (2 tsp): Pure liquid happiness.
  • Sourdough starter (½ cup, unfed/discard): The secret tangy hero of this recipe.
  • All-purpose flour (2 ½ cups): Nothing fancy—just the standard pantry workhorse.
  • Baking soda (1 tsp): Helps your cookies puff up just right.
  • Salt (½ tsp): Don’t skip—salt = flavor amplifier.
  • Chocolate chips (2 cups): Milk, dark, semi-sweet—use whatever makes your soul happy.
  • Optional extras: Chopped nuts, flaky sea salt on top, or even a mix of chocolate chunks if you’re feeling fancy.

Step-by-Step Instructions

  1. Cream the butter and sugars. Beat butter, brown sugar, and granulated sugar together until fluffy. Think “clouds,” not “sand.”
  2. Add egg, vanilla, and starter. Mix until smooth. The sourdough starter might look a little weird at first, but trust the process.
  3. Mix dry ingredients. In a separate bowl, whisk flour, baking soda, and salt. Then add to the wet mixture, stirring just until combined. Don’t overmix—this isn’t CrossFit.
  4. Stir in chocolate chips. Use a spoon or spatula, and try not to eat all the dough at this stage. (Easier said than done.)
  5. Chill the dough. Pop the bowl in the fridge for at least 1 hour. This helps with flavor and prevents cookie spread.
  6. Scoop and bake. Preheat oven to 350°F (175°C). Scoop dough balls onto a parchment-lined baking sheet, leaving space to spread. Bake 10–12 minutes until edges are golden and centers look just set.
  7. Cool (kinda). Let them sit on the tray for a few minutes before transferring to a rack. Or, ignore that and eat one straight away like a true cookie rebel.

Common Mistakes to Avoid

  • Skipping the chill. If you don’t chill the dough, you’ll end up with thin pancake cookies. Unless that’s your thing… but let’s be real.
  • Overbaking. Pull them when the centers still look a little soft. They’ll keep cooking as they cool. Dry cookies = sadness.
  • Using hot butter. Melted butter = greasy, spread-out cookies. Don’t do it.
  • Forgetting the salt. Please. Cookies without salt taste flat and sad.

Alternatives & Substitutions

  • Butter substitute: Coconut oil works, but the flavor will change. IMO, butter is king here.
  • Flour swaps: Half bread flour, half all-purpose = extra chewiness. Want gluten-free? Try a 1:1 GF blend. Results vary, but still tasty.
  • Chocolate options: White chocolate + macadamia, dark chocolate chunks, or even peanut butter chips. Basically, play cookie Tetris with flavors.
  • Nuts or no nuts: Add walnuts or pecans if you’re into crunch. Leave them out if you’re a cookie purist.
  • Starter status: Active or discard works fine. Discard gives more tang, active is milder.

FAQ (Frequently Asked Questions)

Q: Do I have to use sourdough starter?


Technically no—but then you’re just making regular cookies. And why be basic when you can be bougie?

Q: Can I freeze the dough?


Yes! Scoop into balls, freeze on a tray, then stash in a bag. Bake straight from frozen, just add a couple minutes.

Q: How long do they stay fresh?


Around 4–5 days in an airtight container. But let’s be honest: they won’t last that long.

Q: Can I reduce the sugar?


You can, but cookies without enough sugar = bland and sad. Maybe just eat one less cookie instead?

Q: Do I need to feed my starter before using it?


Nope! Use discard. In fact, this recipe is perfect for that neglected jar in the fridge.

Q: Can I make giant bakery-style cookies with this?


Absolutely. Scoop bigger portions and bake a few minutes longer. Giant cookies = giant happiness.
