  • 2 tsp Vanilla extract (Divided between shortbread and caramel)
  • 2 tsp Kosher salt (Divided between shortbread and caramel)

  • 14 oz can Sweetened condensed milk
  • 0.5 cup Corn syrup
  • 0.5 cup Heavy cream
  • 8 oz Dark chocolate (Chopped or in wafer form)
  • as needed Aluminum foil (For lining the pan)

Instructions

  1. Prepare Pan

    Line a 9x13-inch baking pan with two sheets of aluminum foil (one widthwise, one lengthwise) for easy removal. Generously butter the foil.

    Time: PT5M

  2. Make Shortbread Dough

    In a large bowl, whisk together 0.5 cup brown sugar, 2 tsp vanilla extract, 2 tsp kosher salt, and 1 cup melted unsalted butter until smooth. Add 2 cups all-purpose flour gradually, mixing until the dough holds together when pressed but remains crumbly.

    Time: PT10M

  3. Press and Dock Shortbread

    Press dough evenly into prepared pan using wetted fingers or a flat-bottomed object. Dock the surface all over with a fork. Optionally, sprinkle 2 tbsp raw or turbinado sugar on top and press down lightly.

    Time: PT10M

  4. Bake Shortbread

    Bake at 350°F for 17-22 minutes, until golden brown and set. Remove and cool completely on a wire rack (about 2 hours).

    Time: PT2H22M

    Temperature: 350°F

  5. Make Caramel Layer

    In a medium saucepan, combine 0.5 cup unsalted butter, 1 cup brown sugar, 14 oz can sweetened condensed milk, 0.5 cup corn syrup, 0.5 cup heavy cream, and 1 tsp kosher salt. Whisk over medium heat until smooth. Bring to a simmer, whisking frequently for 15-20 minutes, until mixture reaches 236-240°F.

    Time: PT25M

    Temperature: 236-240°F

  6. Pour and Set Caramel

    Pour hot caramel over cooled shortbread. Use an offset spatula to spread evenly and tap pan to remove bubbles. Let cool at room temperature until set (about 30 minutes).

    Time: PT30M

  7. Temper Chocolate

    Chop 8 oz dark chocolate, reserving 2 oz finely chopped for seeding. Melt 6 oz over a double boiler, not exceeding 120°F. Remove from heat, stir in reserved 2 oz, and cool to about 82°F.

    Time: PT15M

    Temperature: 120°F, then 82°F

    Time: PT15M

  9. Slice and Serve

    Lift bars out using foil handles. Peel off foil. Slice into bars with a sharp knife, scoring chocolate first, then pressing through caramel and shortbread.

    Time: PT8M
