Notes

  • Brown sugar adds chewiness; avoid over-mixing for a dense texture.
  • Use a hot, dry knife for clean cuts after chilling.
  • Store at room temperature or freeze for longer storage.
  • Microwave briefly or reheat in oven to refresh texture.
  • Add-ins like chocolate chips, nuts, or spices can customize the flavor.
