Expert Tips

  • Tip 1
    The secret for cutting bars easily is to line the pan with heavy-duty or nonstick foil. When it is time to cut the bars, just lift the baked bar with the foil out of the pan, and cut. This also makes cleanup extra easy.
  • Tip 2
    For a more decorated look: Place melted chocolate chips in resealable food-storage plastic bag. Cut off small piece of corner; drizzle chocolate over bars.
