01 - Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper and set aside.
02 - In a medium bowl, whisk together the all-purpose flour, baking soda, and salt until evenly distributed. Set aside.
03 - In a large bowl, beat the softened unsalted butter, granulated sugar, and packed light brown sugar together using an electric mixer on medium speed until the mixture is light and creamy, approximately 2–3 minutes.
04 - Add the large egg and pure vanilla extract to the creamed butter mixture. Beat until fully incorporated and the batter appears smooth.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed just until the flour is fully incorporated. Avoid overmixing to keep the cookies tender.
06 - Using a spatula, gently fold the sweetened shredded coconut into the cookie dough until evenly distributed throughout.
07 - Using a tablespoon or small cookie scoop, drop rounded balls of dough onto the prepared baking sheets, spacing them approximately 2 inches apart to allow for spreading.
08 - Bake on the center rack for 10–12 minutes, or until the edges are lightly golden while the centers remain soft and slightly underdone.
09 - Allow the cookies to rest on the baking sheets for 5 minutes to set, then carefully transfer them to a wire cooling rack to cool completely before serving or storing.
