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

In a mixing bowl, combine cold butter, sugar, and flour until crumbly. Press into the bottom of the prepared dish and bake for 15-20 minutes.

In a saucepan, combine caramel sauce and toasted pecans over low heat, stirring for 5-7 minutes. Pour over the baked crust.

Melt chocolate chips in a microwave-safe bowl until smooth. Drizzle over the caramel layer and spread evenly.

Let the bars cool at room temperature for 30-45 minutes before cutting into squares.

Serve at room temperature or chilled, and store leftovers in an airtight container.
