                Give your cookies a few minutes on the baking trays to chill out, about five. Then move them over to a rack so they can totally cool down.

                Pop your cookies onto the lined trays, leave a bit of space between each—about two inches is good. Bake for 12 to 15 minutes or until they puff and the edges feel firm. They’ll start to flatten a bit too.

                Scoop out chilled dough—aim for around 1 and a half tablespoons per cookie. Roll between your hands, then give each one a full roll in the powdered sugar and lime zest mix.

                Turn the oven on to 350°F (that’s 175°C). Lay out your baking sheets with either parchment or silicone mats. In a shallow dish, mix together powdered sugar and all the leftover lime zest.

                Pop the mixed dough in the fridge for 20 minutes or so. It sets up a bit and is way easier to work with.

                Keep the mixer on low and slowly pour in your dry stuff. Only mix until it’s just pulled together—don’t overdo it.

                Crack in the eggs one after another, blending between each. Now pour in the key lime juice, coconut extract, plus half that lime zest. Crank mixer to medium-high for a minute, scraping down any batter on the sides to make sure it’s all even.

                With your mixer set to medium, beat the butter, sugar and coconut together. Go until it gets kind of fluffy and it lightens in color.

                Stir salt, baking powder and the flour together in a big bowl. Just give it a quick mix, then put it aside.
