i made these green tea cupcakes:
with white betty crocker cake mix an frosting plus this:
from left to right that is green tea flavored mochi filled with azuki bean, sweetened green tea powder, and azuki bean paste. i put about two and a half tablespoons of the green tea powder in the cake mix and the rest in the frosting. before baking i placed a dalop of the azuki paste in each cup. after baking i cooled the cupcakes on racks. once cooled, i applied the green tea frosting to the cupcakes using wilton tip #1M before topping with a mochi.
observe the anatomy:
by far my favorite cupcakes ever. and applepiejen wouldn't even try them.
