Up until we moved last year, I used a bowl, held it out to the kids and told them to take what they liked. The trick was - the bowl had a creepy looking rubber hand that was sticking up in the middle. The hand is battery operated so that when the kid went to take a piece of candy, it would move to grab the kids hand while saying "Happy Halloween" or "Trick or Treat". It freaked the kids out and it made sure they only took one. For the littlest kids or the ones who were too scared to try, I got the candy out of the bowl for them.
