You don’t have to sit around a fire to enjoy S'mores. Just be sure to watch them carefully under the broiler—the marshmallows can go from perfectly toasted to charcoal in a hurry.
- Position oven rack in the upper third of the oven; preheat broiler.
- Place graham cracker halves on a baking sheet; top each with 1 marshmallow. Broil, with the oven door ajar and watching carefully, until the marshmallows are golden brown, 45 to 75 seconds. Remove from the oven and drizzle each S’more with a little melted chocolate.
