Preheat the oven to 350°F and line a baking sheet with parchment paper.
In a large mixing bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy.
Add in eggs and vanilla extract; beat until well combined.
In a separate bowl, whisk together flour, baking soda, baking powder, salt, and cinnamon.
Gradually mix the dry ingredients into the wet mixture until fully incorporated.
Fold in the oats, chocolate chips, shredded coconut, and pecans.
Scoop dough onto the baking sheet, spacing each cookie about 2 inches apart.
Bake for 10–12 minutes or until the edges are golden brown.
Let cool on the pan for 5 minutes before transferring to a wire rack to cool completely.
