A trillion years ago when I was a wee tot I had a mug with a little mouse in it who would pop his head out to say hello when I was about half done with my cocoa. I'm glad to see that there is a classy adult version now that I'm an ancient lady.
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.
