Preheat oven to 350* F. Line a baking sheet with parchment paper.
In a large bowl using a hand mixer, or in the bowl of a stand mixer fitted with the paddle attachment, cream the non-dairy butter, sugar, and matcha powder until well combined and fluffy.
8 tablespoon Non-Dairy Butter, 1 Cup Granulated Sugar, 1 tablespoon Matcha Powder
Add the non-dairy milk and vanilla and mix on low until well combined.
¼ Cup Non-Dairy Milk, 1 teaspoon Vanilla Extract
Add the flour, baking soda, and salt, and mix on low just until the dough comes together. Then, add the white chocolate chips and stir to distribute.
1 ¾ Cup All Purpose Flour, ½ teaspoon Baking Soda, ¼ teaspoon Kosher Salt, ½ Cup Mini Vegan White Chocolate Chips (plus more for topping)
Scoop the cookie dough with a 3-tablespoon cookie dough scoop onto a parchment-lined baking sheet. Be sure to leave about 3 inches of space between each cookie. I like to bake 8 cookies at a time.
Top each cookie dough ball with a few extra chocolate chips, then bake in a 350* oven for 13-15 minutes, or until the edges of the cookies feel set to the touch.
Allow the cookies to cool of the baking sheet for 5 minutes, then transfer them to a wire cooling rack to continue cooling.
Repeat with the remaining cookie dough.
