Peanutty Playdough Great for eating! 3 1/2 cups creamy peanut butter 4 cups confectioners’ sugar 3 1/2 cups light corn syrup 4 cups dried milk powder This mixture is too thick for most electric mixers, so mix by hand. Kneading works best. Mix ingredients until smooth. Divide into 10 to 15 portions. You can mold and shape into animals, flowers, cars, etc. Decorate with assorted cake sprinkles or small candies, then eat.
