Instructions

Preheat the oven to 350°F (175°C) and line a 9x13-inch baking dish with parchment paper, leaving some overhang.
Cream softened butter and powdered sugar in a mixing bowl until light and fluffy. Add vanilla extract, then gradually mix in flour and salt until the dough forms.
Press the dough evenly into the prepared pan and bake for 18–20 minutes until the edges are lightly golden. Let cool completely.
In a saucepan, combine butter, brown sugar, corn syrup, and sweetened condensed milk over medium heat. Stir constantly until it comes to a gentle boil. Reduce heat and simmer for 5–7 minutes, stirring until thickened.
Pour the caramel over the cooled shortbread layer and spread evenly. Let sit at room temperature for at least 30 minutes or chill to speed up.
Melt chocolate chips and vegetable oil in a microwave-safe bowl in 30-second intervals, stirring between each, until smooth.
Pour the melted chocolate over the caramel layer and smooth it out. Chill until the chocolate is fully set.
Lift the bars out of the pan using the parchment overhang, slice into squares or bars, and serve.

Notes

Use dark chocolate instead of milk chocolate for a richer flavor.

Sprinkle flaky sea salt over the chocolate layer for a salty-sweet contrast.

For gluten-free version, substitute all-purpose flour with a 1:1 gluten-free blend.

Store in an airtight container at room temperature for 5 days or refrigerate up to 10 days.

Freeze up to 3 months and thaw in the fridge overnight before serving.

Let bars sit at room temperature for a few minutes before slicing to avoid cracking the chocolate.
