Here's the recipe for my Red Bean-Stuffed Green Tea Cookies in process.
Liberate your tea from their bags. I used about a dozen tea bags.
Cream the creamables. Butter, white sugar, dark brown sugar, and green tea.
Combine the wet ingredients. Egg, vanilla, and (cooled) brewed green tea.
Add the wet ingredients to the creamables. Mix.
Combine the dry ingredients and add them to the combined wet ingredients and creamables.
Scoop the dough balls, split them in half, and form into flattened disks.
Remove the beans from the fridge. Stuff the cookies.
Freeze the stuffed dough balls for five minutes and then bake.
