Salty, sweet, smoky, and decadent, these bars consist of a pretzel shortbread crust, topped with a thick bourbon caramel, topped with dark chocolate and sprinkled with applewood smoked flaky salt.
Heat the oven to 350F. Line a 8x8 or 9x9 pan with parchment paper.
Combine the flour and sugar in the bowl of a food processor and pulse to combine.
Add the cold, cubed butter and pulse until the mixture starts to resemble coarse meal, with pea-sized butter pieces throughout.
Add the pretzels and pulse until the mixture starts to form large clumps.
Turn the dough out into the prepared pan. Press the dough evenly into the pan using the bottom of a measuring cup or an offset spatula.
Chill the crust for 20-30 minutes.
Bake the crust for 25-30 minutes or until light golden brown. Let the crust cool completely.
Make the caramel:
In a large saucepan, combine the sweetened condensed milk, sugar, golden syrup and butter and mix over low heat until the butter has melted.
Turn the heat up to medium so that the mixture starts to simmer. Stir the mixture over a simmer (slow bubbles) until it turns a deep golden brown and looks like thick caramel fudge, about 10-15 minutes. The mixture will start to pull away from the sides of the pan when stirring.
Remove the mixture from the heat. Add the salt and the bourbon and whisk to combine.
Pour the caramel over the shortbread crust and allow it to cool completely.
Melt the chocolate and the golden syrup in a small saucepan over low heat. Pour the melted chocolate over the caramel layer. Sprinkle the smoked salt over the bars.
Cool until the chocolate is set, then cut into squares. Serve at room temperature.
