Ingredients

Units Scale
For the shortbread layer:
  • 1 cup (2 sticks) unsalted butter, softened
  • 1/2 cup granulated sugar
  • 2 cups all-purpose flour
  • 1/4 teaspoon salt
For the caramel layer:
  • 1 cup (2 sticks) unsalted butter
  • 1 cup packed brown sugar
  • 1/4 cup light corn syrup
  • 1 can (14 ounces) sweetened condensed milk
For the chocolate layer:
  • 1 1/2 cups semi-sweet chocolate chips
  • 1 tablespoon vegetable oil or coconut oil

Instructions

  1. Prepare the shortbread layer (15 minutes + 20 minutes baking):
    • Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal.
    • In a large mixing bowl, cream the softened butter and granulated sugar together until light and fluffy. Gradually add the flour and salt, mixing until just combined.
    • Press the dough evenly into the prepared baking pan. Bake in the preheated oven for 20 minutes, or until the edges are lightly golden. Remove from the oven and let it cool completely.
  2. Prepare the caramel layer (15 minutes + 30 minutes cooling):
    • In a medium saucepan, combine the butter, brown sugar, light corn syrup, and sweetened condensed milk. Cook over medium heat, stirring constantly, until the mixture comes to a boil.
    • Reduce the heat to low and continue to cook, stirring constantly, for about 10-15 minutes, or until the mixture thickens and turns a deep caramel color.
    • Pour the caramel over the cooled shortbread layer, spreading it evenly with a spatula. Let the caramel layer cool completely at room temperature, about 30 minutes.
  3. Prepare the chocolate layer (10 minutes + 1 hour cooling):
    • In a microwave-safe bowl, combine the chocolate chips and vegetable oil or coconut oil. Microwave in 20-second intervals, stirring well between each interval, until the chocolate is completely melted and smooth.
    • Pour the melted chocolate over the cooled caramel layer, spreading it evenly with a spatula. Let the chocolate layer set at room temperature, about 1 hour, or refrigerate for faster setting.
  4. Slice and serve:
    • Once the chocolate is set, use the parchment paper overhang to lift the bars out of the pan. Use a sharp knife to cut the bars into squares or rectangles. Serve and enjoy these decadent millionaire shortbread bars!

Notes

For cleaner cuts, warm your knife under hot water, wipe it dry, and then cut the bars. Repeat this process for each cut.

These bars can be stored in an airtight container at room temperature for up to a week or refrigerated for up to two weeks.

They also freeze well for longer storage. Enjoy making and sharing these rich and indulgent millionaire shortbread bars with family and friends!
