Marshmallow popcorn! my favorite! 3 bags popcorn (pop and take out extra kernels) 2 sticks of butter 16 oz bag of marshmallows 1 cup brown sugar Microwave butter, marshmallows, and brown sugar for 2 1/2 min. Take out and stir. Microwave again for 1 min. Repeat until thin sauce. When done pour over popcorn and mix. YUM!
