Sift almond flour, cocoa powder, espresso powder, and powdered sugar into a bowl.
In a separate bowl, whip aquafaba and cream of tartar until foamy, then slowly add granulated sugar.
Continue whipping until stiff peaks form and you feel smug.
Fold the dry mixture into the meringue gently—think "swipe and turn," not "punch and stir."
Transfer to a piping bag. Pipe circles onto parchment-lined trays. Let them sit for 30 minutes to form a skin.
Bake at 300°F (150°C) for 18–20 minutes. Cool before removing.
For ganache, heat coconut milk and espresso powder. Pour over chocolate chips. Stir until glossy, then add vanilla and salt.
Pipe ganache onto half the shells. Sandwich them like it’s a classy cookie love story.
Chill for 30 minutes (you and the cookies).
Devour responsibly—or hide the box and lie to everyone.
