Instructions

  1. Preheat the oven to 350F. Line a 9x13 inch pan with parchment paper, making sure there is overhang to lift the bars up and set aside. 
  2. Make the shortbread crust: Cream together the softened butter and sugar in a stand mixer with the paddle attachment for about 3 minutes (or a hand mixer is fine too).
  3. Add yolk and vanilla. Mix to combine. Then add the flour and salt and mix just until combined into a shaggy crumbly dough, careful not to over beat. Dough will be soft.
  4. Press into prepared pan in an even layer and bake for 20-22 minutes or until edges are lightly golden then let the crust cool. (The dough is a bit soft/sticky so to make it easier you can place a piece of wax paper over the dough and use the palms of your hands to smooth the surface and then discard the wax paper, you can use a little flour on your hands to press it evenly.
  5. Meanwhile, make the caramel. Add the butter, condensed milk, brown sugar, heavy cream, corn syrup, and salt to a medium sized saucepan. Whisk until combined. Once mixture boils, turn down to medium-low to simmer. 
  6. Continue cooking and frequently whisking until the caramel reaches 225°F. You’ll want to stir often to prevent the bottom from burning. This process will take ~25-30 minutes, try not to rush it. Remove from heat and whisk in vanilla. Then pour over the cooled shortbread crust. (The caramel needs to reach 225-235°F for the caramel to set properly so be sure to use a candy thermometer to check.
  7. Chill in the fridge until caramel sets, ~ 1 ½-2 hours.
  8. Then make the chocolate ganache topping: Microwave the heavy cream for 45 seconds - 1 minute. Then pour the warm cream over the chocolate chips to cover them. (You can very gently press the chocolate chips down so the heavy cream covers them). Let stand for 1 minute, then whisk until smooth and glossy. 
  9. Pour the ganache over the firm caramel and refrigerate again until the ganache is set. Another 1-2 hours or overnight. 
  10. Garnish with flaky sea salt, cut into squares and serve at room temperature. 

Notes

  • The caramel needs to reach 225-235°F for the caramel to set properly so be sure to use a candy thermometer to check. Note: when cooking the caramel, sometimes the butter separates from the caramel. To avoid this stir constantly, avoid turning the heat up too high and too low multiple times, and use a thick saucepan. If it separates, beat it vigorously off heat until combined again and continue cooking until it reaches temp.
