In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to wet ingredients, mixing until just combined. Fold in chocolate chips until evenly distributed throughout the dough.

While the first layer bakes, combine unwrapped caramels and evaporated milk in a microwave-safe bowl. Microwave on power level 5 for 1-2 minutes, stirring every 30 seconds, until completely melted and smooth. Stir in peanut butter until fully incorporated.

Pour the warm caramel sauce over the baked cookie layer, spreading evenly. Drop remaining cookie dough by teaspoonfuls over the caramel layer (it doesn't need to cover completely).

Return to oven and bake for 17-20 minutes until the cookie dough is golden brown, with bubbling caramel and firm edges but soft center.
