Pour the popcorn and dried cranberries into a large bowl. Set aside.
Combine light corn syrup, vanilla extract, maple syrup, salt, vinegar, and sugar in a heavy saucepan. Heat on medium heat, stirring occasionally.
Use a candy thermometer to monitor the temperature. You may need to increase the heat to medium-high heat. Remove the saucepan from heat when it reaches 290 degrees.
Immediately pour the hot syrup over popcorn and use a silicone spatula to combine the popcorn, cranberries, and maple syrup mixture.
Use your hands to grab ½ cup of the popcorn mixture at a time and form balls. It may be hot so be careful. The popcorn will be the size of about 3-inch balls.
Line the popcorn balls on the parchment paper-lined baking sheet.
Notes
t can help to spray your hands with a non-stick cooking spray before forming the popcorn into popcorn balls.
