Making the classic s'mores snack involves nothing more than layering a toasted marshmallow and a piece of milk chocolate between two graham cracker squares. It's a sticky snack beloved by kids and adults alike, and it's usually associated with camping -- or at least an evening sitting around an outdoor fire pit.
But s'mores clean up nicely; they can easily go from outdoor bonfire to Sunday brunch. The simplest way to turn s'mores into something a little more special is to upgrade the ingredients; and since there are only three main ingredients, swapping just one at a time (or more, for the bold) can elevate this campfire treat into a dessert you'd welcome at a dinner party -- or at least a party where shoes are required. Let's start from the outside and work out way in, starting with the cookies.
