Storage: Keep squares in an airtight container in the refrigerator for up to 1 week. For longer storage, freeze layers in the pan before cutting; wrap tightly and freeze for up to 3 months. Thaw in the refrigerator overnight. Make-Ahead: The shortbread base can be baked 1 day ahead and stored covered at room temperature. The caramel can be made 1 day ahead, cooled, covered, and refrigerated; gently reheat to pourable consistency before using. Variations: Use dark or milk chocolate for the topping. Sprinkle with sea salt flakes on the wet chocolate. Add 1/2 cup chopped toasted pecans to the caramel layer.
