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 unsalted butter and granulated sugar together using a hand mixer or stand mixer on medium speed until light and fluffy, approximately 2 to 3 minutes.
04 - Add the large egg and vanilla extract to the creamed butter mixture. Beat until fully combined and smooth.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed just until the flour is incorporated. Avoid overmixing.
06 - Gently fold the sweetened shredded coconut into the dough using a spatula until evenly distributed throughout.
07 - Scoop tablespoon-sized portions of dough and place them on the prepared baking sheets, spacing each about 2 inches apart to allow for spreading.
08 - Bake at 350°F for 10 to 12 minutes, or until the edges are lightly golden and the centers remain soft and slightly underbaked.
09 - Allow the cookies to rest on the baking sheets for 5 minutes, then carefully transfer them to a wire cooling rack to cool completely before serving or storing.
