Preheat oven to 350 degrees F. Line a baking sheet with parchment paper and set aside.
In a medium sized mixing bowl, combine the melted (but not too warm) coconut oil, maple syrup, cashew butter, coconut sugar, matcha powder, sea salt and baking soda. Whisk together.
Into the mixture, add the almond flour, and stir to form a sticky mixture.
Fold in the white chocolate chips and macadamia nuts.
Scoop cookies into balls and place on cookie sheet. These will not spread a lot, so if you'd like the cookies to be flatter and thin, press them down with wet fingers into a cookie shape.
Bake for 10 minutes, until just starting to brown on top.
Allow to fully cool, and the cookies will firm up. Store cookies at room temperature for a week. Alternately, store in an air tight container in the refrigerator for 2 weeks, or frozen for 3 months.
