Line a large baking sheet with parchment paper and set it aside.
Melt the butter in a large pot over low to medium heat. Stir in the corn syrup, vanilla, and salt.
3 tablespoons unsalted butter, ½ cup light corn syrup, 1 teaspoon vanilla extract, ¼ teaspoon salt
Add the mini marshmallows and continue stirring until they’re completely melted and the mixture is smooth.
3 cups mini marshmallows
Add the popcorn and gently stir until it’s evenly coated. Let the mixture cool for about 10 minutes, or until it’s cool enough to handle.
12 cups plain popped popcorn
Lightly butter your hands, then divide and shape the mixture into 12 balls about 3 inches wide. Add more butter to your hands as needed to keep the popcorn from sticking.
Place the popcorn balls on the prepared baking sheet and let them sit for at least 30 minutes to firm up. Serve at room temperature.
Notes
Wrap each popcorn ball tightly in plastic wrap and store them at room temperature for 4 to 5 days.
