Ingredients
  • 115 g (½ cup) unsalted butter, melted and slightly cooled
  • 150 g (¾ cup packed) dark brown sugar
  • 50 g (¼ cup) granulated sugar
  • 120 g (½ cup) sourdough discard, room temperature
  • 1 large egg + 1 egg yolk, room temperature
  • 2 tsp vanilla extract
  • 220 g (1¾ cups) all-purpose flour
  • 1 tsp baking soda
  • ½ tsp baking powder
  • ¾ tsp fine sea salt
  • 200 g (1⅓ cups) dark or semi-sweet chocolate chips
  • Flaky sea salt for topping
Instructions
  1. Melt butter. In a large bowl, melt butter in the microwave or on the stovetop. Let cool for 5 minutes — warm but not hot.
  2. Mix wet ingredients. Whisk brown sugar and granulated sugar into the melted butter until smooth and creamy, about 1 minute. Add sourdough discard, egg, egg yolk, and vanilla. Whisk until fully combined with no streaks of discard visible.
  3. Add dry ingredients. Add flour, baking soda, baking powder, and salt. Switch to a spatula and fold until just combined — do not overmix.
  4. Add chocolate chips. Fold in chocolate chips. The dough will be soft and slightly sticky — that's correct.
  5. Chill the dough. Cover bowl tightly and refrigerate for at least 1 hour — 24 hours is ideal. Cold dough spreads less and develops better flavor.
  6. Preheat oven. Heat oven to 375°F (190°C). Line two baking sheets with parchment paper.
  7. Scoop and bake. Scoop dough into balls using a 2-tablespoon cookie scoop. Place 2 inches apart. Press a few extra chips on top. Sprinkle with flaky salt.
  8. Bake 12–14 minutes. Bake until edges are set and golden but centers still look slightly underdone. They'll continue cooking on the hot pan.
  9. Cool on pan. Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. Centers firm up as they cool.
📝 Notes:
  • Chill time matters. 1 hour minimum, 24 hours maximum flavor. Don't skip it — warm dough spreads flat.
  • Extra egg yolk. Adds richness and chew without making the cookie cakey.
  • Underbake slightly. Pull when centers look underdone — they firm up perfectly as they cool.
  • Freeze dough balls. Scoop, freeze on a sheet for 1 hour, transfer to a zip bag. Bake from frozen adding 2–3 extra minutes.
  • Brown butter upgrade. Brown the butter before mixing for a deeper, nuttier flavor.

Step-by-Step: Sourdough Discard Cookies

Step 1 — Melt and Cool the Butter

Melted butter creates a denser, chewier texture than creamed butter. Let it cool until comfortable to touch before adding sugars — hot butter dissolves sugar completely and causes flat cookies.

Whisk butter and sugar for a full minute — until smooth and glossy.

Step 2 — Add the Sourdough Discard

Add your discard, egg, egg yolk, and vanilla and whisk until completely smooth. The discard should be at room temperature — cold discard can seize the melted butter. If you forgot to take it out, microwave for 10 seconds to take the chill off.

Step 3 — Fold in Dry Ingredients & Chocolate Chips

Switch to a spatula. Add flour, baking soda, baking powder, and salt and fold gently until no dry streaks remain. Then fold in chocolate chips. Stop as soon as it's combined — overmixing develops gluten and makes tough, cakey cookies.

Fold chips in gently — overmixing makes tough cookies.

Step 4 — Chill the Dough (Critical Step)

This is the step most people skip and then wonder why their cookies spread flat. Chilling firms up the butter and allows the flour to fully hydrate. Even 1 hour makes a noticeable difference. 24 hours produces cookies with deeper flavor and better texture.

Press extra chips on top before baking for that bakery look. Don't skip the flaky salt.

Step 5 — Bake and Pull Early

Bake at 375°F for 12–14 minutes. The edges should be set and golden — the centers will still look underdone and slightly glossy. Pull them now. They finish cooking on the hot baking sheet during the 5-minute rest.

Sourdough Discard Cookie Variations

Sourdough Discard Oatmeal Cookies

Replace 60 g of the flour with 90 g (1 cup) rolled oats. Add 1 tsp cinnamon to the dry ingredients. Fold in raisins or chocolate chips. Chill 1 hour minimum.

Sourdough Discard Peanut Butter Cookies

Replace 60 g butter with 120 g (½ cup) creamy peanut butter. Reduce flour to 160 g. Roll balls in granulated sugar and press with a fork before baking.

Sourdough Discard Snickerdoodles

Omit chocolate chips. Add ½ tsp cream of tartar to the dry ingredients. Roll dough balls in 2 tbsp sugar + 1½ tsp cinnamon before baking.

Sourdough Discard Sugar Cookies

Brown Butter Sourdough Cookies

Brown the butter before mixing — cook over medium heat until nutty and amber with brown bits at the bottom. Cool completely before using. Dramatically deepens the flavor.

Tips for the Best Sourdough Discard Cookies

  • Use dark brown sugar. More molasses = more chew and deeper flavor.
  • Melted butter, not softened. Melted butter creates a denser, chewier texture.
  • Extra egg yolk. Adds fat and richness without extra moisture — key to chewy cookies.
  • Chill the dough. Non-negotiable for thick, chewy cookies. Minimum 1 hour, overnight is better.
  • Room temperature discard. Cold discard can cause the melted butter to seize.
  • Don't overbake. Pull when centers still look glossy and underdone.
  • Flaky salt. Press a pinch on top right before baking — elevates every cookie.
  • Bang the pan. Drop the baking sheet from a few inches when cookies come out — creates those crinkled edges.

Sourdough Discard Cookies FAQ

Do sourdough discard cookies taste like sourdough?
No — the tang is subtle and balances the sweetness rather than overpowering it. Most people can't identify sourdough as an ingredient. They just notice the cookies taste more complex and interesting than regular ones.
Why did my sourdough discard cookies spread flat?
Almost always one of three reasons: (1) the dough wasn't chilled long enough, (2) butter was too hot when you added the sugars, or (3) too much discard was added which increased moisture. Measure by weight and always chill the dough at least 1 hour.
Can I use active starter instead of discard?
Yes. Active starter works without any adjustment. Use the same amount (120 g) as the discard.
How long do sourdough discard cookies last?
Up to 5–7 days in an airtight container at room temperature. Add a slice of bread to the container — it absorbs moisture and keeps cookies soft. Do not refrigerate baked cookies — it dries them out.
Can I freeze sourdough discard cookie dough?
Yes. Scoop dough into balls, freeze on a baking sheet until solid, then transfer to a zip bag. Freeze up to 3 months. Bake from frozen at 375°F adding 2–3 extra minutes.
Why are my sourdough discard cookies cakey instead of chewy?
Cakey cookies usually mean: too much flour (use a scale not cups), creamed butter instead of melted, or a whole egg instead of egg + yolk. Stick to melted butter and the egg + yolk combination for chewy results.
Can I make the dough ahead of time?
Yes — up to 72 hours in the fridge. The flavor actually improves the longer the dough rests. After 3 days, bake or freeze the dough balls to stop further fermentation.
