Notes:

  • Store brownies at room temperature in foil covered container for about 2 days.  To keep them fresh, don’t cut them until ready to serve.
  • If you plan to freeze the brownies, bake the brownies and melt the marshmellows on top, then frost when you are ready to serve.  Store brownies packed tightly in a freezer bag or covered freezer safe container.  Freezing brownies can change the texture of them.
  • I wouldn’t recommend freezing frosted brownies as the frosting can crystallize.
