Preheat the oven to 350° F.
In a medium bowl, combine the dry ingredients. Optionally sift the matcha into the rest of the dry ingredients to prevent any dark green spots in the finished cookies.
In a small bowl, whisk together the wet ingredients thoroughly until the mixture is completely homogenous. This may take 2-3 of minutes.
Fold the wet mixture into the dry mixture until a cookie dough comes together. The dough will be slightly wetter than a typical cookie dough. If the dough is too wet to handle, allow the cookies to chill for around 30 minutes in the fridge.
Use a cookie scoop or heaping tablespoon to portion the dough. Place each portion on a parchment paper-lined baking sheet about three inches apart.
Bake the cookies at 350° F for 8-10 minutes.
Remove from the oven and transfer to a cooling rack. Enjoy once they have cooled.
