I made Green Tea Buns the other day. Just use any basic sweet bun dough recipe and add 1 tsp. of green tea powder into the flours mixture. The green tea flavor is real subtle which is good for those who don't like the smell being too strong. I added mung bean paste as filling just because I have some leftover mung bean paste in the freezer. For stronger green tea flavor, add 2 tsp. green tea powder.
