The sushi cupcake idea came from the lovely and amazing Clare Crespo's Hey There Cupcake! but the recipe came from the Barefoot Contessa. Except of course I cannot take direction and had to change it up a bit. Instead of buttermilk I used coconut milk. And I added a tablespoon of lime juice to activate the baking soda (because I took away the buttermilk).
And I made my own cream cheese frosting, I just added lots of coconut. I think that's it.
And I served it with Momma Krause's delicious fudge sauce (as soy sauce).
