Preheat your oven to 350°F (175°C).

In a mixing bowl, cream together softened unsalted butter and granulated sugar until light and fluffy, about 3-5 minutes.

Add eggs one at a time while mixing, then add vanilla extract and mix until well combined.

In another bowl, sift together all-purpose flour, matcha powder, baking powder, and salt.

Gradually add the dry ingredients to the wet mixture, folding gently until just combined.

Scoop dollops of dough onto lined baking sheets and bake for 10-12 minutes until edges are lightly golden.
