Make the Macarons: Measure out all ingredients using a gram scale
Prepare the baking sheets by lining them with a silicone mat or parchment paper. Slide a printed 1 ½ inch template sheet underneath and set aside.
Prepare piping bag to be filled and set aside.
Sift powdered sugar, almond mixture, and cocoa powder together two or three times through a sieve and set aside.
Place the egg whites in a large bowl or in stand mixer with wire whisk attachment. Whisk on low until egg whites become foamy. Add the pinch of cream of tartar. Continue to whisk until soft peaks form. Slowly add in the superfine sugar. Once all of the sugar is incorporated, scrape down the sides with a spatula.
Turn your mixer on medium-high and continue to whisk until you reach a stiff meringue. If adding liquid or gel food dye, do so toward the end of whisking.
Sift 1/3 of the almond flour, powdered sugar, and cocoa powder mixture through the sieve and into the meringue. Fold the dry mixture into the meringue.
Repeat with the remaining mixture. Once all of the dry ingredients are incorporated, the batter will be thick and have a dull shine. Continue to fold. As you do so, the batter will loosen. Stop folding when the batter has a glossy sheen, a “lava-like” consistency, and falls in a ribbon like manner off the spatula.
Transfer the batter into a large pastry bag fitted with a round tip and pipe 1½ inch rounds on the parchment paper following the template.
When all of the rounds are piped on the parchment, rap the sheet pans evenly on work surface a few times. Remove templates from below your parchment paper carefully. Let the batter rest at room temperature for 20-40 minutes.
Pre-heat oven to 350 degrees. Reduce temperature to 300 degrees and bake one sheet at a time for 12 minutes rotating the pan half way through.
Remove from oven and allow to cool.
Match up similar size shells into pairs and sandwich with filling.
Make the Mint Ganache: Add heavy cream, chocolate, and creme de menthe pieces to a measuring cup. Microwave for 30 seconds, whisk. Heat for an additional 15 seconds if needed. Whisk until smooth. Chill until it is the consistency to pipe into cookies.
Fill the cookies with the mint gananche. Place in a sealable container and chill overnight. They are best after they have sat overnight.
