01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, matcha powder, baking soda, and salt until well blended.
03 - In a large bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy, approximately 2 minutes.
04 - Beat in eggs one at a time, ensuring each is fully incorporated before adding the next. Mix in the vanilla extract.
05 - Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
06 - Gently fold in the white chocolate chips until evenly distributed throughout the dough.
07 - Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
08 - Bake for 10 to 12 minutes, or until the edges are set and the centers are still soft.
09 - Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
