Make sure you have all ingredients measured and by your side before starting to make the macarons.
Line two baking sheets with silicone mats. I used the silicone mats with stencils for macarons.
Also have a large piping bag fitted with round tip.
Sift the almond flour and powdered sugar together in a bowl and set it aside.
Place the aquafaba in the bowl of stand mixer, add cream of tartar and whip it for 30 seconds to a minute on a medium high speed; until aquafaba mix looks thick and soupy.
Increased the speed to high and gradually add all the granulated sugar.
Continue to whip on a high speed until stiff peaks form. If you dip the whisk in the aquafaba mix and hold it straight, the peak should stand straight up.
Transfer the aquafaba mix into a wider bowl to help you fold in the dry mixture.
Add the shifted flour and sugar mix and start folding with a spatula slowly. If you want to add any food coloring, this is the time.
Fold the batter forming the letter J with spatula. Be patient and keep doing it until everything comes together.
Keep folding slowly just until the batter is flowing slightly. If you grab a spatula full of batter and hold it over the bowl, the batter should fall in the bowl in chunks and not following like a ribbon. This is the key difference between regular macarons and eggless macarons.
Transfer the batter into the piping bag and pipe 1 1/2 inch circles on the baking sheet. My single sheet has 30 circles so I didn't need to use the second tray.
Slam the tray against the counter to let all air bubbles out and let the tray rest for 30 to 45 minutes until the shells dry. Test this by slight touch of your finger.
Pre heat the oven to 285 F, bake one tray at a time for 20 minutes. Rotate every 5 minutes (this is important!).
Let the macaron shells cool down before removing them from the baking sheet.
