Using a small amount of the butter, grease a large bowl. Place popped popcorn in the large bowl, trying to remove as many unpopped kernels as possible and set aside.
In a large pot melt the unused ¼ cup of butter then add your marshmallows. Stir until melted and smooth.
Remove from heat and quickly stir in vanilla.
Pour mixture over popcorn and stir to coat all kernels as much as possible.
Add in a generous amount of TROLLI® Sour Brite Candy Corn and mix in.
Grab enough popcorn to create balls and firmly press together.
Set on parchment paper until completely cooled.
Serve or wrap individually in plastic wrap and store at room temperature for up to 3-4 days
