Millionaire Shortbread
Ingredients
Crust
- 2½ cups all-purpose flour
- 1 cup powdered sugar
- 1 cup unsalted butter room temperature
- 1 large egg yolk
- ¼ teaspoon salt
Caramel
- 1 can (14 ounces) sweetened condensed milk
- 1 cup brown sugar
- ½ cup unsalted butter cubed
- ½ cup light corn syrup
- ⅓ cup heavy cream
- ¼ teaspoon kosher salt
- 1 teaspoon vanilla extract
Chocolate Topping
- ½ cup heavy cream
- 8 ounces semi sweet baking chocolate finely chopped
- Flaky sea salt for sprinkling on top
Instructions
Shortbread Crust
- Preheat the oven to 350°F. Line a 9"x13" baking pan with parchment paper.
- In a large mixing bowl, cream together the ingredients for the crust.
- Pour the mixture into the baking pan and press down firmly.
- Bake at 350°F. If using a light-colored of glass pan, bake for 25-30 minutes. If using a dark pan, cook for 20-25 minutes. Edges of the crust should be golden.
- Allow to cool while you prepare the caramel filling.
Caramel
- In a medium saucepan, stir together the sweetened condensed milk, brown sugar, butter, corn syrup, cream, and salt until well combined.
- Cook over medium heat, stirring frequently, until the mixture darkens, begins to pull away from the sides of the pot, and reaches 235°F, 12 to 14 minutes.
- Stir in the vanilla extract. Immediately pour the mixture over the shortbread crust, smoothing with a spatula.
- Allow to cool completely, about 1 hour.
Chocolate Topping
- Place finely chopped chocolate in a medium mixing bowl.
- Heat cream in a small saucepan until steaming but not boiling, stirring often.
- Gradually add the hot cream to the bowl of chocolate, and whisk until the mixture is smooth.
- Wait until cool enough to handle but not hardened. Pour the chocolate over the cooled caramel, smoothing it with an offset spatula.
- Sprinkle the surface with flaky salt, if desired. Allow the bars to chill until set in the refrigerator, 30 minutes to 1 hour.
- Using the parchment paper edges, remove the bars from the pan and slice as desired.
Notes
- Storage: Store in an airtight container on the counter for up to 3 days, or store covered in the refrigerator for up to a week.
- Freezer Directions: Wrap tightly and freeze for up to 2 months. Thaw in the fridge or at room temp before enjoying.
