This is the most popular Halloween candy in New York and New Jersey

Instacart, the popular grocery delivery and pick-up platform, has officially released its Halloween candy data report — and the results may surprise you.

"With the spookiest time of the year finally here, Americans are getting in the spirit by filling their Halloween candy baskets early," Laurentia Romaniuk, Instacart’s trends expert, tells Fox News. "According to Instacart purchase data from last year, customers purchased 2.5 million pounds of candy in the weeks leading up to October 31."

"Whether they’re buying trick-or-treat candy early or enjoying the candy for themselves, candy is a central part of Halloween’s spirit and festivities. For many, it’s often more important than having a costume," she continues, adding that when it comes to the top candy in America, candy lovers are fond of bite-sized chocolate treats with Peanut M&M’s and M&M’s topping the charts as the number one and two top candy products sold on Instacart in terms of weight.

Rounding out the top five are Reese’s Peanut Butter Cups, Hershey’s Milk Chocolate, and Twizzlers, in third, fourth, and fifth place, respectively.

However, people living in New York and New Jersey's tastes appear to be a little more refined, with Ferrero Rocher Hazelnut Chocolates taking the top spot as each state's most popular Halloween candy.

Next door, in Connecticut, Twizzlers are the #1 Halloween treat.

New York and Connecticut also ranked as two of the states with the smallest sweet tooths in the nation, along with North Carolina, Florida and Iowa.

To dig into all things Halloween candy this year, Instacart partnered with The Harris Poll to gather survey responses from some 2,000 Americans nationwide, with questions ranging from favorite and least favorite candies to "trick-or-treat confessions" (read: mom stole the candy).
