No reviews

Soft, chewy chocolate chip cookies that put your sourdough starter discard to work. A quick cold-cream method keeps spread in check for crinkly tops, while a short (or overnight) chill deepens flavor and chew.

  • Total Time: 36 minutes
  • Yield: 12 large cookies

Ingredients

  • All-purpose flour — ¾ cup + 1 tsp (95 g)

  • Bread flour (or sub AP; see note) — 1 cup + 1 tsp (125 g)

  • Fine sea salt — 1 tsp (5 g)

  • Baking soda — ¼ tsp

  • Baking powder — ½ tsp

  • Large egg — 1

  • Sourdough starter discard (unfed) — ½ cup (125 g), room temp

  • Vanilla extract — 1 tsp (5 g)

  • Unsalted butter, cold & cubed — 8 tbsp (113 g)

  • Light brown sugar — ½ cup (100 g)

  • Granulated sugar — ½ cup (100 g)

  • Chocolate chips (semi-sweet or milk) — 1 ½ cups (340 g)

Instructions

  1. Whisk dry ingredients: In a small bowl, whisk bread flour, all-purpose flour, baking soda, baking powder, and salt until evenly combined.

  2. Mix wet ingredients (egg/discard): In another small bowl, whisk the egg, sourdough discard, and vanilla until smooth and glossy.

  3. Cold-cream butter & sugars: In a stand mixer fitted with a paddle on low speed, beat cold cubed butter with brown sugar and granulated sugar just until small crumbles form (45–60 seconds). Add chocolate chips; mix on low 30–45 seconds to coat. Scrape the bowl.

  4. Bring dough together: Add the dry mix; blend on low 20–30 seconds until sandy. Pour in the egg/discard mixture; mix on low 20–30 seconds until the dough pulls from the sides. Finish by hand with a spatula to ensure no dry pockets remain.

  5. Scoop & chill: Scoop 12 large dough balls (about two scoops stacked per cookie). Place on a parchment-lined tray, cover, and chill at least 2 hours (24 hours for best flavor/texture).

  6. Bake: Preheat the oven to 375°F (190°C). Arrange 6 dough balls per sheet with ample spacing. Bake 15–17 minutes, until edges are golden and centers look slightly under-baked. Cool on the sheet 5 minutes, then transfer to a rack. Cookies set as they cool for that soft, chewy middle.

Notes

  • Flour swap: Using all-purpose flour instead of bread flour yields slightly less chew but still a plush, soft cookie.

  • Why chill: Resting hydrates starches and lets the discard’s mild acidity deepen flavor and improve chew.

  • Make-ahead: Chill up to 48 hours. Or freeze portioned balls up to 2 months; bake from frozen at 375°F (190°C) adding 1–2 minutes.

  • Size: For smaller cookies (24), bake 10–12 minutes.

  • Mix-ins: Try half chips/half chopped chocolate for varied melt; finish warm cookies with a pinch of flaky salt.
