Get your popcorn ready. Any kind is good :) You don't have to measure exactly 1 cup, just eye-ball it.
A pinch of salt... (Don't add salt if you're using margarine/salted butter)
Brown sugar... You can also use caramelized white sugar :)
And a pinch of cinnamon.
Microwave with 10 second intervals until butter is completely melted.
Drizzle over popcorn and enjoy! I found 3 tsp. = 1 cup of popcorn but you might want more/less depending on your preference.
I recommend eating with a spoon because it's sticky :) This recipe makes enough for about 2 cups of popped popcorn. Or 6 tsp. of topping :)
Enjoy! The sauce will thicken as it sets, so you may have to re-microwave it :)
