Line a large baking sheet with parchment paper then set aside.
Place the butter and sugar in a medium-sized bowl, then cream them together until light and fluffy.
½ cup unsalted butter, 1 cup granulated sugar
Beat the egg and vanilla into the mixture until everything is combined.
1 large egg, 1 teaspoon pure vanilla extract
Add the key lime juice and lime zest to the mixture.
2 teaspoons key lime juice, 1 teaspoons lime zest
Then add the flour, baking powder, salt, and baking soda. Mix until just combined and no dry streaks remain.
1 ½ cups all-purpose flour, ½ teaspoon baking powder, ¼ teaspoon salt, ⅛ teaspoon baking soda
Fold in the sweetened coconut flakes.
1 cup sweetened coconut flakes
Use a two-tablespoon cookie scoop to measure the dough onto the prepared baking sheet. Since this baking sheet is going into the fridge, it's ok to place the dough side by side so it can chill.
Refrigerate for at least 1 hour then preheat the oven to 350°F. Line a separate baking sheet or two baking sheets with parchment paper.
Place the cookie dough balls on the prepared baking sheet at least 1 inch apart. If desired, sprinkle the tops with lime zest and coconut.
Bake for 9 to 11 minutes or until the edges begin to brown.
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a cooling rack to cool completely.
