This pie could be made with any flavor of instant pudding you like best. I suggest chocolate or fudge for the full s'more experience. Using a commercially available graham cracker crust saves time but a homemade crust would be a great alternative. The topping is essentially a meringue frosting. You have seen it here before and you will see it here again. If you would rather skip the homemade "marshmallow" feel free to try some mini marshmallows. Give the finished pie at least a few hours in the freezer to set up before serving. It can be stored in the freezer for several days.
This recipe makes more topping than needed to cover the pie. Use ⅔ of the topping for the pie and get creative with the remaining ⅓. We heaped it on graham crackers for a sticky sweet treat. Makes 12 voluminous servings or many smaller ones.
