Tips and Tricks for Making S’mores Bars

  • Do use nonstick aluminum foil to line the pan. This will make the bars a no-fuss mess. When the bars are gone, simply lift the foil and throw it away
  • Don’t try to substitute mini marshmallows in the recipe. They will not cook well like the fluff. They will dissolve into virtually nothing.
  • You can easily make S’mores Bars in advance. They will last at room temperature for up to 1 week
