S'mores Chocolate Bark

Line a rimmed baking sheet with foil. (Take care to avoid wrinkles.)

Place chocolate in a medium microwave-safe bowl; microwave on Medium for 1 minute. Stir, then continue microwaving on Medium, stirring every 20 seconds, until melted. (Alternatively, place in the top of a double boiler over hot, but not boiling, water. Stir until melted.)

Combine graham crackers and marshmallows in a small bowl. Stir half of the mixture into the melted chocolate. Scrape the chocolate onto the foil and spread it into a 9-inch square. Sprinkle with the remaining graham crackers and marshmallows, pressing any large bits in. Refrigerate until set, about 30 minutes.

Transfer the bark and foil to a cutting board. Use a sharp knife to cut into 1 1/2-inch pieces.
