01 - Preheat oven to 350°F. Line two baking sheets with parchment paper and set aside.
02 - In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until evenly distributed. Set aside.
03 - In a large bowl, beat the softened butter and granulated sugar together using a hand mixer or stand mixer on medium speed until light and fluffy, about 2 to 3 minutes.
04 - Add the egg and vanilla extract to the butter mixture. Beat until well combined and smooth.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed just until the flour is incorporated. Do not overmix.
06 - Using a spatula, gently fold the sweetened shredded coconut into the cookie dough until evenly distributed throughout.
07 - Scoop tablespoon-sized portions of dough and roll into balls. Place them on the prepared baking sheets, spacing about 2 inches apart to allow for spreading.
08 - Bake in the preheated oven for 10 to 12 minutes, or until the edges are lightly golden and the centers remain soft and slightly underdone.
09 - Allow the cookies to rest on the baking sheets for 5 minutes, then carefully transfer them to a wire rack to cool completely before serving or storing.
