Storage: Keep in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. For make-ahead, prepare and bake without marshmallow topping; store covered at room temperature up to 1 day, then add marshmallows and chocolate chips and bake as directed before serving. Variations: Substitute milk chocolate chips or add chopped nuts to the batter. For a firmer marshmallow layer, briefly broil the topping after baking (watch closely to prevent burning).
