Millionaire Shortbread Caramel Chocolate (Print Version)

Buttery shortbread, soft caramel, and chocolate ganache finished with sea salt for a sweet-salty treat.

# Ingredients:

→ Shortbread crust

01 - 1 cup salted butter, softened to room temperature
02 - 2/3 cup granulated sugar
03 - 1 large egg yolk, room temperature
04 - 1 tsp pure vanilla extract
05 - 2 1/4 cups cake flour, spooned and leveled
06 - 1/4 tsp kosher salt

→ Caramel layer

07 - 1 cup salted butter
08 - 1 (14 oz) can sweetened condensed milk
09 - 1 cup light brown sugar, packed
10 - 1/2 cup heavy cream
11 - 1/4 cup golden or light corn syrup
12 - 1 tsp vanilla

→ Chocolate layer

13 - 2 cups semi-sweet chocolate
14 - 1/2 cup heavy cream
15 - Flaky sea salt, for finishing

# Steps:

01 - Preheat the oven to 350°F. Line a 9x13 inch pan with parchment paper, ensuring there is an overhang to lift the bars, and set aside.
02 - Cream together the softened butter and granulated sugar in a stand mixer with the paddle attachment for about 3 minutes (or use a hand mixer). Add egg yolk and vanilla, then mix to combine. Add the cake flour and kosher salt and mix just until combined into a shaggy, crumbly dough. Press the dough evenly into the prepared pan and bake for 20-22 minutes or until edges are lightly golden. Let the crust cool.
03 - In a medium-sized saucepan, combine butter, sweetened condensed milk, brown sugar, heavy cream, and light corn syrup. Whisk until combined. Heat the mixture to a boil, then reduce to a medium-low simmer. Cook while whisking frequently until the caramel reaches 225°F (about 25-30 minutes). Remove from heat, whisk in vanilla, and pour over the cooled shortbread crust. Chill for 1 1/2 to 2 hours until set.
04 - Microwave the heavy cream for 45 seconds to 1 minute. Pour the warm cream over the semi-sweet chocolate and let sit for 1 minute. Whisk until smooth and glossy. Pour the ganache over the set caramel layer and refrigerate until firm, about 1-2 hours or overnight.
05 - Sprinkle flaky sea salt over the set chocolate ganache. Cut into squares and serve at room temperature.

# Notes and Tips:

01 - Refrigerator storage: Store bars for up to 2 weeks.
02 - Freezer storage: Bars can be frozen for up to 3 months.
03 - Use a candy thermometer to ensure the caramel reaches 225-235°F for proper setting.
