Preheat oven to 350 (F).
Line two large baking sheets with parchment paper.
In a large bowl using a whisk, beat together the browned butter and both sugars until well combined.
Whisk in the eggs and yolk, beating until well combined.
In a separate large bowl, whisk together the flour, baking soda, cinnamon, salt, oats, coconut, pecans, and chocolate chips.
Fold the dry ingredients into the wet ingredients, mixing just until combined.
Scoop 2-inch balls of cookie dough onto the prepared baking sheets, leaving 2-inches between each ball so they have room to spread.
Bake in preheated oven for 12 minutes, or until cookies are golden and firm at the edges.
Sprinkle with sea salt, if desired.
Cool cookies on baking sheet for 10 minutes before transferring them to a wire rack to cool completely.
