In a large bowl, beat together the butter, brown sugar, and vanilla until combined. Beat in the eggs, one at a time, until combined. Add the flour, baking soda, and salt. Stir in the chocolate chips, oats, pecans, and coconut. Optional: Cover the bowl and chill the dough overnight or up to 72 hours. This chill time allows the dough to develop even more flavor.When ready to bake, preheat the oven to 350°F (175° Celsius). Sprinkle a 10-inch oven-safe skillet with sea salt. Grab the dough from the fridge and scoop mounds of cookie dough into the skillet, arranging in an even layer. Don't worry too much about making it perfect. Bake for 30-35 minutes. Remove from the oven, let cool 5 minutes-ish. Add ice cream and sprinkle with sea salt (if desired). DIG in!
