Special equipment: parchment paper or silicone mat
Preheat the oven to 170 degrees F. Line the back of a cookie sheet with parchment paper or a silicone mat.
Put the chocolate chips in a stainless steel bowl and place in the oven. Heat the chips until they hold their shape but melt when you touch them, 8 to 12 minutes. You want the chocolate to melt without getting hot or it will be ruined. Stir until smooth and shiny.
Pour the melted chocolate out onto the prepared cookie sheet. Spread evenly into an 1/8-inch-thick rectangle. Sprinkle with the cookies and drizzle the Sorghum Caramel over the top. Sprinkle with salt. Gently pick up the pan and drop it on the counter a couple of times. This will help the ingredients settle into themselves. Leave the bar to cool at room temperature, about 1 hour. Break into irregular 3-inch pieces.
Fill a glass with ice water and set aside.
Combine the sugar, sorghum and butter in a saucepan and heat over medium until the butter melts, 3 to 5 minutes. Stir in the sweetened condensed milk, bring to a simmer and cook about 1 minute. Lower the heat and continue to cook, stirring constantly, until a soft ball forms when the caramel is dropped in the glass of ice water or the temperature reads 240 degrees F on a candy thermometer, about 20 minutes. Let the mixture stand for 5 minutes before using.
Sorghum syrup is made from the sweet juice of the sorghum plant, a variety of cereal grass. It's popular in the south as a sweetener for baked goods. You can find it at natural food stores or specialty online retailers.
