  • 1 (3.2-ounce) bag plain microwave popcorn
  • ½ cup unsalted butter
  • 1 cup packed light brown sugar
  • 1 tablespoon light corn syrup
  • 20 large marshmallows or 3 cups mini marshmallows


  • Pop popcorn and place in a large bowl, removing any un-popped kernels.
  • Melt butter in a medium saucepan over medium-low heat. Add brown sugar and corn syrup and cook, stirring, until well blended. Add marshmallows and stir continuously until all melted, about 5 minutes.
  • Pour mixture over popcorn and mix well. Spread popcorn out on parchment paper or a greased baking sheet and let sit for about 10 minutes to set up.



Choose Your Favorite Popcorn: One 3.28-ounce bag of microwave popcorn contains 5 tablespoons of un-popped kernels, which makes 10–11 cups of popped popcorn. So for this recipe, you can buy 11 cups of plain pre-popped popcorn, pop 5 tablespoons of your own kernels, or pop 1 bag of plain microwave popcorn.
