Notes

  1. Cut them cleanly--To cut clean, even squares, let the brownies cool completely before slicing.
  2. Storage--Store the brownies in a sealed container at room temperature for up to 4 days, or freeze for longer storage. Separate layers with sheets of parchment paper to prevent them from sticking together.
