  • 3/4 cup light corn syrup
  • 1/4 cup butter
  • 3 cups powdered sugar
  • 1 cup marshmallows
  • 2 teaspoons water
  • 2 teaspoons vanilla
  • 1/8 teaspoon salt
  • 20 cups popped popcorn
  • Food Coloring of your choice


  1. In a small pot over medium high heat combine corn syrup, butter, sugar, marshmallows, water, vanilla and salt. Keep stirring until mixture comes to a boil.
  2. Separate popcorn into bowls depending on how many different colors you are using. If you are using 5 colors, separate popcorn into 5 bowls - this will make it safer so you don't mix colors.
  3. Carefully (it's hot) pour your syrup mixture into bowl of popcorn. Make sure to equally distribute into each bowl of popcorn. For example if you are using 5 colors, separate the syrup into 5 equal parts.
  4. Add 2 drops of food coloring to the bowl.
  5. With a spoon stir popcorn so every piece is coated with syrup mixture. Tip: Use a different spoon for each bowl so you don't mix colors.
  6. Using your hands shape into popcorn balls (whatever size you prefer). You have to do this quickly before the syrup cools off. You can use food safe plastic gloves sprayed with nonstick spray to make this easier to do.
