What Is America’s Favorite Halloween Candy? If you’re having a hard time figuring out what candy you should get for the little trick-or-treaters visiting your door this Halloween, here’s what America’s saying. Reese’s Peanut Butter Cups are America’s favorite Halloween candy according to a phone survey of over 1,000 adults. A Monmouth University pool says the chocolate and peanut butter combo accounted for 36 percent of the votes followed by Snickers at 18 percent. M&M’s came in third with 11 percent. Shockingly, candy corn came in with 6 percent of the votes and tied with Hersey’s plain chocolate bars. Starburst, Skittles, and Tootsie Pops came in at 5, 4 and 2 respectively. What is the worst Halloween candy? When you eat your peanut butter cup, do you eat both cups or do you save one for later?
