Prepare a 9x9 baking dish with parchment paper and spray with non-stick baking spray.

Melt four tablespoons of butter in a microwave-safe dish and pour over graham cracker crumbs. Stir to combine. Sprinkle mixture evenly into the baking dish.

Melt the remaining 2 tablespoons of butter in a large saucepan over medium high heat. Add 16 ounces of the mini marshmallows and continuously stir to combine until the marshmallows are melted and smooth

Stir in the popcorn and mix until the popcorn is well coated. Fold in the frozen mini chocolate chips. Immediately transfer the mixture into the prepped baking dish pressing it firmly into an even layer. Sprinkle with the remaining 1 cup of marshmallows and torch the top.

Let it harden for about 20 minutes and then cut and serve
