- 3 (2.9 ounce) bags microwave popcorn, popped
- 1 cup brown sugar
- 2/3 cup sweetened condensed milk
- 1/2 cup corn syrup
- 1/4 cup butter
- 1/2 teaspoon vanilla extract
- Pour popcorn into a large bowl.
- Combine brown sugar, condensed milk, corn syrup, butter, and vanilla extract in a saucepan over medium heat. Cook, stirring often, until a candy thermometer reads 234 degrees F (112 degrees C), about 5 minutes. Pour over popcorn; stir to coat evenly.
- Scoop some of the popcorn mixture onto a piece of plastic wrap. Gather and twist the plastic wrap to shape into a ball. Place popcorn ball on a baking sheet lined with parchment paper; repeat with remaining mixture. Let cool until set, about 5 minutes.
