Pop popcorn kernels according to package instructions. Set aside.
1/2 cup popcorn kernels
In a large pot, heat butter over medium heat, until melted. Add miniature marshmallows, and stir until melted.
½ cup unsalted butter, 2 cups miniature marshmallows
Remove from the heat and add popcorn, stirring well until all popcorn is evenly coated with marshmallow mixture.
Spray your hands with nonstick spray, and grab a handful of the popcorn mixture to form your popcorn balls. You may need to re-spray every few popcorn balls made.
Place the popcorn balls onto a plate and after they’ve all been formed, sprinkle with Christmas sprinkles.
