Preheat the oven to 350°F. While it's warming up, line a 9x13-inch baking dish with foil or parchment paper. For easy removal later, leave some overhang. Grease the foil or paper lightly.
Take a large bowl and cream together the softened butter, brown sugar, and vanilla extract. You'll want to keep blending it until it's smooth.
Once it's well-mixed, beat the eggs in one at a time. Keep beating them until the are incorporated fully.
In a separate bowl, whisk together the flour, baking soda, and 1/2 teaspoon of sea salt flakes. Once it's mixed, gradually add it to the wet mixture from the previous step. Stir it in until it is just combined. Stir the chocolate chips in also.
Add half of the dough you've made to the baking dish and press it down evenly.
In a saucepan over medium heat, combine the evaporated milk and unwrapped caramels. Continually stir the caramels until they melt. You want them as smooth as possible.
Pour the caramel over the pressed cookie dough in the baking dish. Add the remaining cookie dough in dollops, about the size of a teaspoon.
Bake for about 25-30 minutes. The top should be golden brown. The caramel should be bubbling.
Remove it from the oven and add some sprinkles of sea salt flakes.
Now comes the hard part - waiting! Allow the bars to cool off until they reach room temperature. Take hold of the foil or paper overhang and lift them out. Slice them up and serve!
