Line a baking sheet with parchment paper and set aside.
If you are making your own popcorn you will want to make about 10 to 12 cups of finished popcorn. Set it aside to cool once you have made it before continuing with the recipe.
Place the popcorn (store bought, homemade or even microwave popcorn) in a large bowl and set aside.
10 to 12 cups Popcorn
In a large saucepan over medium heat, melt the butter. Add in the marshmallows. With a rubber spatula, frequently stir the marshmallows until they are melted (about 3 - 5 minutes).
4 cups mini marshmallows, 2 tablespoons butter
Pour the melted marshmallow mixture over the popcorn and stir to coat the popcorn with the marshmallow mixture. Stir in the M&M's.
3/4 cup M&M's
Scoop out one cup of popcorn mixture and place on the parchment lined baking sheet. Allow to slightly cool for about 1 minute.
Spray your hands with cooking spray. Take each scoop of popcorn mixture and press the mixture together to form a ball shape. Place back on a baking sheet to finish cooling. Repeat to make 12 popcorn balls.
If desired, while the popcorn mixture is still warm, press additional M&Ms into the popcorn balls. You can also press additional Halloween candies into the popcorn balls if desired.
In a microwave safe bowl, melt the chocolate wafers according to the package. Drizzle the melted chocolate over each ball. Allow the chocolate to firm up and the popcorn balls to completely cool before serving.
