1. Preheat your oven to 325°F (163°C) and grease a 9×13 inch baking pan.
2. In a large bowl, cream together the butter, granulated sugar, and powdered sugar until light and fluffy, about 3-4 minutes.
3. Add in the vanilla extract and mix until incorporated.
4. Gradually add the flour and salt, mixing until the dough just comes together.
5. Press half of the dough evenly into the prepared pan, creating a firm and even layer.
6. Bake the crust in the preheated oven for 20 minutes, or until the edges are lightly golden.
7. While the crust is baking, combine the caramel sauce and heavy cream in a small saucepan over low heat, stirring until smooth.
8. Pour the caramel mixture over the baked crust, spreading it evenly.
9. Sprinkle the sea salt flakes over the caramel layer to taste.
10. Crumble the remaining dough over the caramel layer, covering most of the surface.
11. Return the pan to the oven and bake for an additional 25-30 minutes, or until the top is lightly golden.
12. Allow the bars to cool completely in the pan before cutting into squares.

As you bake, remember that cooking is a form of storytelling. Each step, each ingredient, is a part of the narrative that makes these bars uniquely yours. Just like the meals I’ve prepared over the years, these bars are an expression of love and care.
