- Form the Popcorn Balls:
Let the mixture cool slightly—just enough so it’s safe to handle but still pliable. Lightly coat your hands with nonstick cooking spray or rub with a bit of butter to prevent sticking. Scoop out approximately 1 cup of the mixture and press it into a firm ball using your hands. Repeat with the remaining mixture. - Decorate and Cool:
Place the formed popcorn balls onto a sheet of waxed paper or a silicone baking mat to cool completely. If using, press holiday candies or sprinkles into the surface while they’re still slightly warm so they adhere well.
Let the popcorn balls set for about 30 minutes before serving or packaging. Store in an airtight container at room temperature for up to 3 days for best freshness.
