Instructions

1. 1

   Gather all ingredients. Grease a 9x9-inch square baking pan and line with parchment paper so parchment paper overhangs edges by 1-inch.

2. 2

   Pulse cookies in a food processor until fine crumbs form.

3. 3

   Meanwhile, melt 1/2 cup butter and add to the cookie crumbs in the food processor; pulse until combined.

   Press crumb mixture firmly and evenly into the bottom of the prepared baking pan using the flat bottom of a measuring cup or glass. Refrigerate for 30 minutes.

5. 5

   Meanwhile, combine 6 tablespoons butter, sweetened condensed milk, brown sugar, and salt in a saucepan. Cook over medium-high heat until boiling, stirring often.

6. 6

   Reduce heat to medium. Cook, stirring continuously, until a candy thermometer reads 230 to 235 degrees F (110 to 113 degrees C) or until thickened and darkened in color, 6 to 8 minutes. Pour caramel over the chilled shortbread base and spread evenly. Refrigerate for 2 hours.

7. 7

   Once caramel has chilled, combine dark chocolate chips and remaining 2 tablespoons butter in a microwave safe bowl.

   Microwave chocolate on High until melted and smooth, 1 to 2 minutes, stirring every 20 seconds. Spread melted chocolate mixture evenly over the chilled caramel layer.
