Ingredients

Scale

Shortbread

  • 1 cup (2 sticks) unsalted butter, softened
  • 1/2 cup (107 g) packed dark brown sugar
  • 1/4 cup molasses
  • 2 teaspoons ground ginger
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground cloves
  • 1/4 teaspoon kosher salt
  • 2 3/4 cups (330 g) all-purpose flour

Caramel

  • 1 (14 oz) can sweetened condensed milk
  • 2/3 cup (142 g) dark brown sugar
  • 6 tablespoons unsalted butter
  • 1 teaspoon ground ginger
  • 1/4 teaspoon kosher salt

Chocolate Topping

  • 10 oz chocolate (preferably 60% cacao), chopped
  • 1 oz gingersnaps, crushed
  • Flaky sea salt (optional)

Instructions

  1. Prepare Shortbread: Preheat your oven to 350°F and line a 13″ x 9″ metal baking pan with parchment paper, ensuring there is an overhang on two opposite long sides. In a large bowl, beat softened butter, dark brown sugar, molasses, ground ginger, cinnamon, cloves, and salt using a handheld mixer on high speed until the mixture is light and fluffy, about 2 to 3 minutes. Add the all-purpose flour and mix on low speed just until fully combined. Spread this dough evenly into your prepared pan.
  2. Bake Shortbread: Bake the shortbread in the preheated oven until it is lightly browned around the edges, approximately 20 to 22 minutes. Allow it to cool at room temperature in the pan for at least 30 minutes before adding the caramel layer.
  3. Make Caramel: In a small saucepan, combine sweetened condensed milk, dark brown sugar, unsalted butter, ground ginger, and salt. Cook over medium-low heat, stirring frequently, until the sugar dissolves, about 2 to 3 minutes. Increase the heat to medium-high and bring the mixture to a simmer. Reduce the heat to medium and continue to cook, stirring constantly, until the mixture thickens and darkens in color to about 235°F on an instant-read thermometer, around 5 to 6 more minutes. The caramel will froth and bubble but will smooth out with continuous stirring.
  4. Pour Caramel: Remove the caramel from heat and carefully pour it over the cooled shortbread base. Spread the caramel evenly with a nonstick spatula. Be cautious as the caramel will be very hot. Let the caramel set at room temperature for at least 30 minutes or up to overnight until firm.
  5. Melt Chocolate: Place chopped chocolate in a microwave-safe bowl. Microwave in 30-second intervals, stirring thoroughly between each, until the chocolate is fully melted and smooth, about 1 minute and 30 seconds total.
  6. Assemble Bars: Pour the melted chocolate over the set caramel layer. Spread evenly with the back of a spoon or an offset spatula. Sprinkle crushed gingersnaps and flaky sea salt (if using) on top. Refrigerate the bars until the chocolate is firm, about 2 hours.
  7. Slice and Serve: Using the parchment paper overhang, lift the bars out of the pan onto a cutting board. Cut into squares with a sharp knife and serve.

Notes

  • For best results, use high-quality dark chocolate with around 60% cacao for a balanced bittersweet flavor.
  • Crushing the gingersnaps coarsely adds texture and a complementary spicy note to the bars.
  • Make sure the caramel reaches 235°F to ensure the perfect thickened consistency.
  • Bars can be stored in an airtight container in the refrigerator for up to one week.
  • Allow the bars to come to room temperature slightly before serving to soften the chocolate and caramel layers.
