Recipe Tips

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

Special ExtraFor extra flavor, garnish dessert with toasted chopped pecans in addition to the remaining chopped cookies.

SubstituteSubstitute bittersweet baking chocolate for the semi-sweet chocolate.
