Line a baking sheet with parchment paper.

Melt butter and marshmallows in the top of a double boiler. Stir in sea salt.

Place cereal in a large bowl. Stir in melted marshmallows and then chocolate chips.

Drop mixture by the tablespoon full on prepared baking sheet. Allow to cool to harden. (You can use the freezer to speed this along. The boys preferred them stored in the fridge.)
