Making the box is easy:
Begin with a deep-sided baking pan lined with parchment.
Add a stack of paper napkins for messy fingers (be sure to weigh them down so they don’t blow away).
Fill box with graham crackers, milk chocolate, and marshmallows, then get creative with whatever other ingredients you like.
Mix it up with different types of cookies or crackers and an assortment of unusual toppings. Fresh fruit, nut butters, and preserves are all unexpectedly delicious additions.
Finish by packing everyone a skewer and let the gooey fun begin!
