When I was a kid we had a couple Japanese exchange students stay with our family and they would often bring kokeshi as a gift. I still have those lovely dolls and wouldn't turn down a cookie version either!
Oh man is there a lot going on here. Those cupcakes alone look light and moist and delightful and then you go and pile on some pretty, fluffy, buttery icing mmmmmmm. And THEN you make little heart cookies and you ice them BUT you use MORE icing to make them all fancy and swirly and amazing. Then you PUT IT ON THE CUPCAKE! I'm so exhausted. I can't eat. I need a nap.
