Star Wars macarons are just the latest in a long line of Star Wars related things that show how avid and dedicated the fan base is. As far as pastries and sweets go Macarons are pretty close to the top of the list. They're never too heavy, can come in a whole handful of flavors and are colorful as ever. To add to this already stacked list of pros, you can now add that they come in R2D2 and Chewbacca skins.
At this point, there are no surprises when it comes to what the Star Wars fan base is capable of. They eat, sleep and, as demonstrated, eat Star Wars. Macarons aren't the easiest pieces of pastry to make, but if you're going to do it, you might as well do it right and this is what doing it right looks like.
