Preheat your oven to 160 C/ 320 F and line a baking sheet with parchment paper. Crack the eggs and place the egg whites in the bowl of a stand mixer. Start whisking the egg whites until soft peaks form.
Gradually add the sweetener, 1 tbsp at a time, until you reach medium-stiff peaks. Finally, beat the salt and vanilla extract and turn off the mixer. Add the shredded coconut.
Gently fold in the coconut flakes, starting at the bottom and sweeping to the sides. Do that for 1-2 minutes until the coconut is distributed. Be careful not to knock out the air from the batter.
Using a cookie scoop, divide the batter into 12 portions on the baking sheet. Leave a space of 1 inch (2.5 cm) between the macaroons. Using the back of the cookie scoop, make a slight indentation to look like a nest.
Bake for 15 to 20 minutes, until golden brown. While it’s hot, repeat the indentation you made previously to emphasize it. Set the baking sheet aside to cool.
Add the heavy cream to a bowl. Using a hand mixer, beat until light and creamy. Keep a third of the whipped cream in the bowl, and divide the remaining into 2 small bowls.
Add a drop of each food coloring to the bowls. Whisk until the color of each batch is homogeneous. Transfer each batch to a separate piping bag.
Snip ½ -1 cm ( ¼ – ½ ) off the ends of the piping bags. Pipe a little bit of each color in a triad to resemble eggs in a nest. You can pipe the “eggs” in one movement or swirl them into ovals.
