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.
The flavor combo here sounds so incredibly sweet that it makes my teeth hurt a little. But if that peanut butter is just salty enough, I bet these are a chewy, gooey delight! I sure do love the look of 'em!
