ingredients

For the Cookies:

  • 1 cup (2 sticks / 227g) unsalted butter, softened

  • ¾ cup (150g) granulated sugar

  • ¾ cup (165g) packed brown sugar

  • ½ cup (120g) unfed sourdough starter discard (100% hydration)

  • 2 large eggs, room temperature

  • 2 tsp vanilla extract

  • 2¾ cups (345g) all-purpose flour

  • 1 tsp baking soda

  • 1 tsp fine sea salt

  • 2 cups (340g) semi-sweet chocolate chips or chunks

Optional Add-Ins:

  • ½ cup (60g) chopped walnuts or pecans

  • Flaky sea salt, for sprinkling

Directions

1. Cream Butter & Sugars

  • In a stand mixer or large bowl, beat the softened butter, granulated sugar, and brown sugar on medium speed for 2–3 minutes until light and fluffy.

2. Add Wet Ingredients

  • Mix in the sourdough discard, eggs, and vanilla until fully combined.

3. Combine Dry Ingredients

  • In a separate bowl, whisk together the flour, baking soda, and salt.

  • Gradually add the dry ingredients to the wet mixture, mixing just until no flour streaks remain.

4. Fold in Chocolate

  • Gently stir in the chocolate chips (and nuts, if using) with a spatula.

5. Chill the Dough

  • Cover the dough and refrigerate for at least 1 hour (or up to 48 hours for deeper flavor).

6. Preheat & Scoop

  • Preheat oven to 375°F (190°C) and line baking sheets with parchment paper.

  • Use a 3-tablespoon cookie scoop to portion dough onto sheets, spacing 3 inches apart.

7. Bake to Perfection

  • Bake for 10–12 minutes until edges are golden but centers are still soft.

  • Let cool on the baking sheet for 5 minutes, then transfer to a wire rack.

8. Optional Finishing Touch

  • Sprinkle with flaky sea salt while warm for a sweet-salty contrast.

Frequently Asked Questions

1. Can I use active sourdough starter instead of discard?

Yes, but the flavor will be milder. Discard adds a more pronounced tang.

2. Why is chilling the dough important?

Chilling prevents overspreading and allows the flour to hydrate, resulting in thicker, chewier cookies.

3. Can I freeze the dough?

Absolutely! Portion dough balls and freeze for up to 3 months. Bake straight from frozen, adding 1–2 extra minutes.

4. My cookies spread too much—what went wrong?

Butter may have been too soft, or dough wasn’t chilled long enough. Ensure your oven is fully preheated.

5. Can I make these gluten-free?

Yes! Substitute gluten-free 1:1 flour blend and ensure your starter is gluten-free.
