These indulgent bars feature a buttery shortbread base, a rich and gooey salted caramel layer, and a smooth chocolate topping. They're the perfect sweet and salty treat for any occasion.
Storage: Keep bars in an airtight container at room temperature for up to 3 days, or refrigerate for up to 1 week. For longer storage, freeze in a single layer for up to 2 months. Make-Ahead: The shortbread base can be baked 1 day ahead and stored covered. The caramel can be made 1 day ahead, gently reheated, and poured. Variations: Use dark chocolate chips or add 1/2 cup toasted pecans to the caramel layer. For a firmer texture, chill bars before slicing.
