                After the popcorn’s cool, snap it into chunky pieces. Pour it into a container with a tight lid if you’re saving some for later.

                Lay the sticky popcorn out on a foil-topped baking tray sprayed with cooking spray. Let it chill out and harden up for around 10 to 15 minutes.

                Drizzle your warm marshmallow caramel all over the popcorn. Gently toss until every piece looks glossy.

                Take the pot off the stove right away and mix in the vanilla. It’ll smell amazing instantly.

                Turn the heat down. Drop in all the marshmallows and keep stirring so they melt into a smooth, oozy mess.

                Start with your butter in a big pot over medium flame. Toss in brown sugar and corn syrup, and stir until it’s one silky blend—no grainy bits.

                Make your popcorn however you like—microwave, stovetop, or air-popped. Toss out those hard unpopped bits and put the popcorn in a giant bowl.
