Preheat oven to 375F. (Optional: prepare baking sheets by lining with parchment paper.)
Combine flour, baking soda, salt, and matcha powder in a medium bowl and set aside.
2¼ cups flour, 1 teaspoon baking soda, 1 teaspoon salt, 2 tablespoons matcha powder
In a large bowl, beat the butter, sugars, and vanilla together until creamy.
1 cup butter, ¾ cup granulated sugar, ¾ cup packed brown sugar, 1 teaspoon vanilla extract
Add eggs, one at a time, beating well after each addition. Gradually add in the flour mixture.
2 large eggs
Add in the chocolate chips and stir well to combine.
12 ounces (2 cups) chocolate chips, semi-sweet or white chocolate
Using a cookie scoop or teaspoon, drop rounded tablespoon-sized dough onto ungreased baking sheets. (I use parchment paper) Space the dough at least 3 inches apart to allow the cookies to spread as they bake.
Bake for 9 to 11 minutes, until just barely golden brown on the edges.
Cool 2 minutes on the baking sheet, then remove to a wire rack to cool completely.
