Preheat the oven to 350 degrees. Grease 10 or 12 inch oven safe skillet.
To make the the caramel add the coffee and brown sugar in a medium sauce pot. Bring a a boil and boil 5 minutes. Slowly add the coconut milk and butter, whisk to combine. Bring back to a boil, reduce heat to a low boil and cook 5 -10 minutes longer, until the sauce has thickened and coats the back of a spoon. If using a candy thermometer do not let the sauce go above 180 degrees F. Remove from the heat and stir in the Kahlua and salt, set aside.
To make the cookie dough, in a large mixing bowl or bowl of a stand mixer, add the oatmeal, flour, brown sugar, baking soda, salt, melted coconut oil, eggs and vanilla and beat until combined and the dough holds together (the dough will seem oily, this is good). Mix in about 1 cup of the chocolate chunks.
Turn half the batter out into a prepared pan, pushing the dough into pan. Then pour about 1 cup of the caramel overtop and spread it out all over the cookie. Sprinkle with some chocolate chunks and then place the remaining half of the dough over the chunks. Some of the chunks will most likely be sticking out, that is fine. Don't worry about it looking perfect. If desired you may even add more chocolate to the top. Most of the time I do.
Bake for about 20-25 minutes, just do not over bake. Underdone is always better in my opinion. Remove from the oven and let sit 5 minutes. Top with the thinly sliced apples, a good drizzle of the remaining caramel and then finish with the roasted pecans and a sprinkle of sea salt. DEVOUR and enjoy! Oh, and if you are feeling real crazy, add a scoop of ice cream!
