Salted Caramel 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 6 caramel squares and 1/2 teaspoon water in a small bowl; microwave on High just until melted, 30 to 60 seconds. Immediately stir the melted caramel thoroughly into the melted chocolate. Scrape the mixture onto the foil and spread it into a 9-inch square.

Combine the remaining 6 caramel squares with 1/2 teaspoon water in the small bowl and microwave on High until melted, 30 to 60 seconds. Immediately drizzle the caramel over the chocolate and sprinkle with salt. 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.
