Brown the butter first Get a saucepan and turn the heat to medium. Add the butter and brown for approximately 6-8 minutes, or until you see brown bits at the bottom and a little bit of white foaming action on the surface. Once you see this turn the heat off and remove it from the stove. Let it cool down completely.
In a small mixing bowl combine the all-purpose flour, salt, baking soda and matcha. Using a sifter sift the ingredients to remove any clumps. The matcha will often times be clumped together. Sifting it will ensure the matcha is evenly mixed to create a vibrant green color.
Take a mixing bowl and add the butter, granulated sugar and brown sugar and mix until well mixed. Add the egg and vanilla extract and mix until you get a nice light creamy texture. Use a stand mixer to help mix it faster, but a hand mixer will also work fine. It will just take an extra minute or two to get the texture.
Add the sifted dry ingredients into the wet and mix with a spatula. Hand mixing will ensure the dough will not raise and fall flat in the oven by adding excess air to the dough.
Add the white chocolate chips and mix until well incorporated into the dough.
Use a cookie scoop/ice cream scoop 3 tablespoon to scoop the cookie dough (I get 8 cookies with this recipe). I let the cookies rest in the fridge for 30 minutes.
Take the cookies out of the fridge and preheat your oven to 350 degrees Fahrenheit
Cover your baking sheet with parchment paper and place the cookie dough 3 inches apart. Since this recipe uses less butter I like to roll the dough and press down to give it a cookie flatten shape. Bake for 10-12 minutes. Take out of the oven immediately and let it rest for 10 minutes on the baking sheet.
Move the cookies to a cooling rack. Enjoy!
