Finally, finally, I remembered to buy some matcha for baking.
On the menu:
Chocolate Cupcakes with Azuki Filling, from Chockylit
Green Tea Cupcakes, taken from this Pomegranate Green Tea Cupcake recipe, also from Chockylit
Matcha Cream Cheese frosting that I found over on this lovely blog, Une-Deux Senses.
Notes: I added Meyer lemon zest to the frosting, perhaps a bit too much, because it seems to cover up the delicate taste of the matcha, though you can still detect a hint of it.
