After bringing 2 cups sugar and 1/2 cup milk to a boil, add 1 teaspoon vanilla (or any other flavoring you want) and food coloring. Stir until the food coloring is all mixed in, and pour in a large bowl over 8 cups of popcorn. Stir very well. Then lay out on foil to give it some time to “unstick” before combining colors. You could also turn these into popcorn balls really easily.
We sprinkled some Christmas sprinkles on some of the colors. Just have fun!
