Bake cupcakes according to package directions, but use gold foil liners (for a royal prince-ly feel). Let cool completely.
To color frosting, mix 3 drops royal blue, 3 drops violet and a smidge of black food coloring paste with a tub of white frosting. Pipe or spread on as desired.
Sprinkle on edible gold stars glitter, and put a single red candy rose on top.
