Directions

1. Preheat oven to 350 degrees. Line baking sheets with parchment paper or nonstick baking mats; set aside. In a medium bowl, whisk together flour, baking soda, salt, and baking powder.
2. Beat butter and sugars with a mixer on medium-high until pale and creamy, about 3 minutes. Reduce speed to medium. Add eggs, 1 at a time, beating well after each addition. Beat in vanilla.
3. Reduce speed to low, and slowly add flour mixture, beating until just incorporated. Beat in oats, chocolate, pecans, and coconut until combined. (Dough can be refrigerated for up to 3 days.)
4. Using a 1 1/2-inch ice cream scoop or a small spoon, drop dough onto baking sheets, spacing 3 inches apart.
5. Bake until edges of cookies begin to brown, 11 to 13 minutes. Transfer baking sheets to a wire rack, and let cool for 5 minutes. Transfer cookies to racks. Let cool. (Cookies can be stored up to 3 days.)
