According to YouGov, they did a study on the most as well as least popular Halloween candies among the youth (ages 8 to 17, the most likely to go trick or treating on their own):
The most favorite of them all...Reese's Peanut Butter Cups. So, if you want to be the neighborhood favorite...get bags of those.
The Top 10 Favorites:
1) Reese's Peanut Butter Cups
4) Kit Kat
8) Sour Patch Kids
10) Hershey bars
As far as the LEAST favorites? Tootsie Rolls is the MOST unpopular, then candy corn. I disagree...Tootsie Rolls are underrated! They come in different shapes, sizes, AND flavor! Candy corn is just disgusting.
