Edible star glitter! I will always be blown away by the variety of food decorations that look inedible but are in fact safe! Also, the little fondant mug on top of this cupcake is filled with butterbeer so you get a little sip before you eat the creamy goodness below. Genius.
I love a good culinary "gotcha" every now and again. This one is especially well executed with the matching saucer and the doily and the little floating marshmallows. I know I'd be fooled and delighted!
