Prepare the Popcorn:

1. Pop the Popcorn: Place the popped popcorn in a large mixing bowl, removing any unpopped kernels. Set aside.

Melt the Marshmallow Mixture:

1. Melt the Butter: In a large saucepan over medium heat, melt the butter.
2. Add Marshmallows: Add the marshmallows and stir constantly until fully melted and smooth.
3. Add Flavoring: Remove from heat and stir in the vanilla extract. If desired, add a few drops of red or pink food coloring and mix until evenly tinted.

Combine with Popcorn:

1. Coat the Popcorn: Pour the melted marshmallow mixture over the popcorn. Use a spatula or greased hands to gently mix until the popcorn is evenly coated.

Add Valentine Candy:

1. Fold in Candies: Quickly fold in the Valentine’s Day candies while the mixture is still warm, distributing them throughout the popcorn.

Shape the Popcorn Balls:

1. Form Balls: Lightly grease your hands with butter or non-stick spray. Scoop out portions of the coated popcorn mixture and form into balls about 3 inches in diameter.
2. Place on Sheet: Place the shaped popcorn balls onto a parchment-lined baking sheet.

Set and Serve:

1. Cool: Let the popcorn balls cool completely to firm up.
2. Serve or Package: Wrap each ball in plastic wrap or place them in treat bags for gifting, or serve on a festive platter!
