Preheat your oven to 375°F. Line your baking sheet with either parchment paper, a silicone baking mat, or spray the pan with your favorite cooking spray.
In a medium bowl, whisk the flour, baking soda, sifted matcha, and salt. Set to the side for later.
In a large bowl, using an electric mixer or a stand mixer, cream together the softened butter and both sugars until they are fully combined and the mixture looks like a sandy dough. Then, mix in the egg and vanilla until everything is blended together and the mixture looks like wet dough.
Slowly add the dry ingredients to the wet ingredients, mixing until the mixture has created a smooth dough. Once the dough has been formed, fold in the white chocolate chips or macadamia nuts.
Using a one inch cookie scoop or a spoon, place the rounded dough onto the baking sheet, leaving about 1-2 inches between each cookie dough.
Bake for 7-9 minutes, or until the cookies are no longer shiny from the dough. Don’t let the edges get golden, or they will be too crispy.
Allow the cookies to cool on the baking sheet for about 3-5 minutes before transferring them to a wire rack to finish cooling.
Enjoy your delicious matcha cookies with a hot cup of tea, a glass of your favorite milk, or as a delightful treat anytime!
