                Heat your oven to 350°F. Line a couple of baking sheets with silicone mats or parchment paper so your cookies don't stick.

                In a medium bowl, whisk together the flour, baking powder, and salt until well combined. Set aside for now.

                In the bowl of a stand mixer with the paddle attachment, beat the butter, granulated sugar, and shredded coconut together until light and fluffy, about 2-3 minutes.

                Add the eggs one at a time, mixing well after each. Then add the key lime zest, key lime juice, and coconut extract. Mix until everything is well combined. The mixture might look a bit curdled - that's normal!

                With the mixer on low speed, gradually add the flour mixture to the wet ingredients. Mix just until combined - don't overmix. The dough will be thick and a little sticky.

                Pour the powdered sugar into a small bowl. Using a small cookie scoop (about 1½ tablespoons of dough), scoop balls of dough and drop them directly into the powdered sugar.
              
              
              
                07 - 
                Roll each dough ball in powdered sugar until completely coated. Place on your prepared baking sheets about 2 inches apart - they'll spread a bit while baking.
              
              
              
                08 - 
                Bake for 9-11 minutes, just until the cookies are puffy and the edges feel firm to the touch. The centers will still be soft, and they'll continue cooking on the hot pan.
              
              
              
                09 - 
                Let the cookies cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely. The crinkle effect will become more pronounced as they cool.
