Prepare 2 baking sheets with silicone mats, teflon, or templates and parchment paper. Fit a piping bag with a round piping tip. Set aside. Preheat oven to 275°F.
Pulse the almond flour and powdered sugar in a food processor and sift into a bowl. Discard any large chunks. Whisk the dry ingredients and set aside.
In a clean stand mixer bowl, add egg whites and sugar. Whisk to combine and place bowl over a double boiler. Heat, whisking regularly, until the sugar dissolves, about 30- 90 seconds. Remove the bowl from the double boiler and carefully dry off the bottom.
Place the bowl in the stand mixer and whisk on a medium speed (KitchenAid 4) until you almost have stiff peaks, 10 minutes. Add your coconut flavor and color. Beat until you have stiff peaks, another 5 minutes.
Add the dry ingredients to the bowl and switch to a paddle attachment. Beat on the lowest speed for about 10 seconds, or until the ingredients are combined. Finish macaronage by hand. Fold until the batter flows like lava.
Pipe macaron shells onto prepared baking sheets. Let the macarons dry until you can lightly brush the tops with your finger (30 mins for me). Bake for 18 minutes, rotating every 6 minutes. Gently poke shell, if it is firm, remove from the oven to cool. If they wiggle, add another minute or two.
Let the macaron shells cool on the sheet for 5- 10 minutes before transferring them to a cooling rack.
