Preheat oven to 350°F. Line two baking sheets with parchment paper or silicone baking mats.
In a large mixing bowl, beat together the softened butter, brown sugar, and granulated sugar until light and fluffy. This should take about 2-3 minutes with a hand mixer or stand mixer on medium speed.
Beat in the egg and vanilla extract until fully combined.
In a separate bowl, whisk together the flour, baking soda, baking powder, cinnamon, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to over mix.
Gently fold in the shredded coconut and chopped pecans using a spatula until evenly distributed.
Using a cookie scoop or a tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each cookie slightly with the back of the spoon or your fingers.
Bake for 10-12 minutes, or until the edges of the cookies are golden brown and the centers are set. The cookies will firm up as they cool.
Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
