Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.

In a large mixing bowl, cream together softened unsalted butter and granulated sugar until light and fluffy.

Gradually add all-purpose flour to the creamed mixture and mix until just combined.

Press half of the dough into the bottom of the prepared baking pan to form an even layer.

Bake the crust for 10-12 minutes until lightly golden brown.

In a saucepan over low heat, combine soft caramel candies and heavy cream until melted and smooth.

Pour the caramel mixture evenly over the baked crust and crumble the remaining dough on top.

Sprinkle sea salt over the surface and return to the oven to bake for an additional 15 minutes.

Allow to cool completely before cutting into bars and serving.
