HEAT oven to 375°F.
COMBINE cookie mix, butter, egg and water in medium bowl. Mix until soft dough forms. Stir in chocolate chips and 1/3 cup chopped peanuts. Use rounded measuring teaspoons of dough to make 3/4-inch balls. Roll in remaining chopped peanuts. Place on cookie sheet.
BAKE 10 to 12 minutes or until light brown. Spoon a scant 1/2 teaspoon peanut butter on top of warm cookie. Press chocolate candy onto peanut butter. Transfer to wire rack. Cool to allow chocolate to set.
