Recipe Tips

For Easy CuttingFor best results, spray the knife with cooking spray before using to cut the chilled dessert into bars. Or, clean the knife by dipping the knife blade into warm water, then wiping it dry with paper towels between cuts.

NoteThese chocolatey bars can be refrigerated up to 1 week before serving.

Special ExtraFor extra flavor, sprinkle 1/4 cup chopped peanuts over frosted dessert along with the reserved chopped cookies.
