A good looking cake is worth so much on its own. You almost don't want to cut into it for fear of destroying the design. But man! Aren't you glad you did? There are rainbows inside! The world needs to know.
When I was a kid I was obsessed with those fancy chocolates that look like seashells. They are used to spectacular effect here. At first I thought those were real shells! I'm filing this one away for ideas later in the year for sure.
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.
