Sour bread chocolate cookies (with video)

These cookies creatively repurpose leftover sourdough bread into a soft, chewy base, studded with rich melted chocolate crumbs for a delightful contrast of textures. Ideal for afternoon tea, dessert platters, or zero-waste baking projects, they offer a comforting balance of tangy sourdough and sweet chocolate. The final texture is tender yet slightly resilient, with a glossy surface and gooey center.

Tips

  • Use day-old or slightly dried sourdough for optimal crumb texture—fresh bread may make dough too moist
  • Do not overmix after adding flour to avoid tough cookies
  • Bake just until edges set; underbaking slightly yields chewier results
  • Store in an airtight container for up to 5 days, or freeze unbaked dough balls for later use
