Instructions
Step 1: Make the Shortbread Crust
Preheat oven to 350°F (175°C). Line a 9×13 inch baking dish with parchment paper, leaving an overhang for easy removal. Cream together the softened butter and powdered sugar until light and fluffy (about 2-3 minutes). Beat in the vanilla extract. Gradually add the flour and salt, mixing until a dough forms.
Press the dough evenly into the prepared baking dish. Bake for 18-20 minutes, or until lightly golden. Let cool completely.
Step 2: Create the Caramel Layer
In a medium saucepan, combine the sweetened condensed milk, butter, brown sugar, corn syrup, and salt. Cook over medium heat, stirring constantly, until it comes to a gentle boil. Continue cooking and stirring for 6-8 minutes, or until thickened and slightly darkened. Be sure to stir constantly to prevent burning!
Pour the caramel evenly over the cooled shortbread. Spread it out with a spatula and let cool completely.
Step 3: Add the Chocolate
Melt the chocolate chips and vegetable oil together in a microwave-safe bowl in 30-second intervals, stirring until smooth. Pour over the caramel layer and spread evenly. Let the chocolate set at room temperature (or chill for faster setting).
Step 4: Slice and Enjoy!
Once the chocolate is set, lift the cookies out of the dish using the parchment paper overhang. Slice into bars or squares and serve.
Cook’s Notes
- Stir the caramel constantly to prevent burning. It should be thick but still spreadable.
- Let the chocolate set at room temperature to avoid condensation. If refrigerating, cover the dish.
- Ensure the shortbread is completely cool before adding the caramel.
