Hi, I'm new.
Couldn't help but smile at your post, as a female Star Wars fan myself and the aunt of a 2-year-old girl who loooves Darth Vader. (If you tell her, "Darth Vader!" she'll pucker up her lips and do the raspy breathing; it's hysterical.)
Anyway, I made something for a recent Star Wars party that might count as "not as dark" ... I found a simple line drawing of a Vader head and made a bunch of "chocolate Vaders" out of decorating chocolate. I just put the pattern under some wax paper and kept moving it, drawing the lines with dark chocolate and filling them in with milk chocolate. After they set, I put them on iced cupcakes with red and black cake sparkles around them.
Believe it or not, it was really easy and looked great. Hey, you could even use pink cake sparkles around them if you truly wanted to go girly!
I'll post a photo if I can figure out how to ... and I could even you the pattern if you'd like; I think I still have it saved.
