Be With You!
A long time ago in a galaxy far, far away, Princess Aly and Prince Charming came across a Jedi master chef. He used the Force to create tools called cookie cutters. He supplied them with 4 shapes: Darth Vader, Yoda, Boba Fett, and a stormtrooper.
Aly and Charming used a shortbread recipe and added green food coloring to a portion of the dough to make Yodas. They also experimented with Wilton cookie icing, but the tips on the icing bottles were a bit large for the grooves of the cookies.
In case you have not been lucky enough to meet a Jedi, you can buy the same set Aly used from Williams-Sonoma (includes 4 cookie cutters and a shortbread recipe):
