Preheat the oven to 350 degree F. Line two baking sheets with parchment papers or silicone baking mats.

In a large bowl, combine together the flour, baking powder, salt and matcha powder. Whisk well and then set aside.

In a big bowl, using an electric mixer, beat the butter on medium speed for 30 seconds. Slowly add the sugar and continue beating for 2 minutes.

Add the eggs one at a time and beat until incorporated. Add the flour mixture and beat on low speed until combined.

Scoop 24 heaping tablespoonfuls of dough into plates. Form each dough into a ball. Roll the balls in the powdered sugar and then place on the prepared baking sheet at least 2-inch apart, placing 12 balls in each sheet.

Bake for 13 to 14 minutes, or until the surface of the cookies have cracked and puffed up. Immediately transfer the cookies to a cooling rack to fully cool down.
