Line 3 cookie sheets with silicone baking mats or parchment paper. Prepare a piping bag with round tip (#804).

In a small bowl, add the powdered evaporated cane juice and almond meal. Set aside.

In an electric stand mixer bowl fitted with a whisk attachment, add the egg whites and salt. Turn the stand mixer on high speed and start a timer.

Slowly sprinkle in the 50g of evaporated cane juice.  Whip this mixture for 5 minutes. Mixture should form stiff peaks.

Slowly add the vanilla paste and almond extract and whip for 2 more minutes.

Sift the dry ingredients into the stand mixer.  Fold the batter by hand with a silicone spatula until everything is fully incorporated. Do not under mix and do not over mix! Mixture should be in between “plopping” off the spatula and “flowing” like a thick ribbon.

Scoop the batter into the prepared piping bag and pipe 1” buttons onto the prepared cookie sheets, each about 2” apart.  Tap the pans on the counter HARD a few times to deflate any air pockets.  Sprinkle on the rainbow nonpareils.

Preheat the oven to 350 degrees Fahrenheit. Let the piped macarons sit at room temperature for ~1 hour. Shells should form on the surface of the macarons (when you can tap the surface, they shouldn’t stick to your finger at all). Bake one tray at a time for ~8 minutes, or until the fluffy “feet” form and the surfaces of the macarons are dry and turn a VERY light golden brown (they go from perfect to an unappealing tan in less than a minute, so keep those eyes peeled!). Let cool completely on the cookie sheets.

Pipe your frosting of choice (Cream Cheese Frosting is delicious!) onto half of the macaron shells, then sandwich the remaining shells on top. Serve immediately.
