Start by preheating your oven to 350°F (175°C). This ensures that your cookies bake evenly.
In a mixing bowl, combine the softened butter, brown sugar, and white sugar. Using a whisk or electric mixer, cream them together until the mixture is light and fluffy.
Crack the egg into the bowl and add the vanilla extract. Mix until well combined, ensuring that everything is evenly incorporated.
In a separate bowl, whisk together the all-purpose flour, kosher salt, and baking soda. This step helps to evenly distribute the leavening agent.
Gradually add the dry mixture to the wet ingredients, mixing until just combined. Avoid overmixing to keep your cookies tender.
Gently fold in the coconut M&Ms until they are evenly distributed throughout the dough.
Using a cookie scoop or tablespoon, drop rounded balls of dough onto a prepared baking sheet lined with parchment paper, spacing them about 2 inches apart.
Place the baking sheet in the preheated oven and bake for about 10-12 minutes or until the edges are lightly golden. The centers may look slightly underbaked, but they will continue to set as they cool.
Once baked, remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Enjoy these delightful treats warm or at room temperature!
