Step 2

In a separate bowl, combine flour, matcha powder, and salt, and gradually add this mixture to the butter mixture.

Step 3

When ready to bake, preheat the oven to 325°F (165°C) and line 2 baking sheets with parchment paper.

Step 5

Roll out dough to a ¼ inch (6mm) thickness on a floured surface and cut circles with a 2-inch (5cm) round cutter. Place cookies on the prepared baking sheet. Gather and reroll any scraps.

Step 6

Sprinkle cookies with sugar, tapping gently so that the sugar sticks, and then bake for 18-22 minutes, until the cookies are dry and firm (they should not take on any color). Transfer to a wire rack to let cool completely.
