Preheat oven to 325 degrees F.

In a mixing bowl, dump your graham crackers and mix in the melted butter.

In a muffin pan (if you have mini tart molds with removable bottoms even better) scoop about a tablespoon of the crumbs and press evenly into the cavity of the mold and up the sides.

Bake for 10 minutes until the crust browns a little. The crust will harden as it cools.

In a saucepan, heat up the cream and pour it over the chocolate. Let sit for a minute or two. Stir until the chocolate is melted.

Pour the chocolate into the tarts. Top with marshmallow.

Let this sit for about half an hour so the chocolate has time to set and the marshmallows almost glues onto the chocolate.

When ready to eat, stick the tarts under the broiler for a few minutes or until the marshmallow browns. Enjoy!
