Here's something that I lifted from another site, modified and sold to my customers right before taking off for San Fran. An easy recipe which was nice as I was trying to get out of town.
87g (3/4 C.) Powdered sugar 145g (5 oz) Chilled, cubed butter 1 3/4 C. AP Flour 3 Yolks 7 g (2 T.) Matcha Sugar for dusting
Whisk sugar and tea together. Add the butter to the sugar mixture and combine in a mixer until creamed. Add flour and mix until just combined. Add the yolks until a ball forms. Remove the dough from the mixer and form into a 1/2" thick rectangle on a silpat or parchment. Cut into your desired shape, sprinkle with sugar and freeze for at least 2 hours.
Oven to 350F. Separate your cookies onto the baking sheet and bake 15 minutes or until slightly browned on the bottom. Enjoy!
