Ready to dive into making these delicious bars? Follow these steps and let the fun begin:

1. Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.
2. In a large bowl, combine the cake mix, melted butter, and 1/3 cup evaporated milk. Stir until the mixture forms a thick batter.
3. Press half of the batter into the prepared baking dish, spreading it evenly. Bake for 8-10 minutes, or until just set.
4. While the base layer is baking, melt the caramels with the remaining 1/3 cup of evaporated milk over low heat, stirring until smooth.
5. Remove the baking dish from the oven and sprinkle the chocolate chips and chopped pecans evenly over the base.
6. Pour the melted caramel mixture over the chocolate chips and nuts, ensuring an even layer.
7. Drop spoonfuls of the remaining batter over the caramel layer. Don’t worry if it doesn’t cover completely; the batter will spread as it bakes.
8. Bake for an additional 15-18 minutes, until the top is set and slightly golden.
9. Allow the bars to cool completely before cutting into squares. This step is crucial as it helps the layers set perfectly.

Remember, patience is key here. As tempting as it is to dig in right away, letting the bars cool ensures they hold their shape beautifully.
