In a heavy-bottomed pan, dry-roast the black sesame seeds over medium heat for 3–5 minutes. Continuously stir till the seeds start to pop and look plump. They will also release a nutty, fragrant aroma.
Once the seeds are well toasted, turn off the heat. Only then add the dessicated coconut, as it will roast from the residual pan heat. Gently stir for a minute before transferring the mixture to a plate. Let it cool. Don’t leave it on the pan, or it may burn from the pan's heat.
Once the mixture cools down completely, transfer it to a blender along with powdered jaggery and cardamom powder (if using). Pulse grind the mix a few times until it turns into a coarse powder. Important: Only pulse grind. Do not grind continuously, or the mixture will become a paste.
Transfer the coarse mixture onto a plate. Now, lightly grease your palms with ghee or oil and shape the mixture into small balls. Remember, since these are pops, the balls should be bite-sized. Roll them tightly between your palms to form small, smooth, round balls.
Once your Laddoos are ready, gently insert lollipop sticks for a "pop" effect. Don’t press the stick too hard or insert it too deeply, or the Laddoo might break. Serve immediately.
