Whisk together wet ingredients in one mixing bowl and dry ingredients in a separate mixing bowl. Sift dry mixture to remove any large clumps.
Add dry mixture to wet. Stir in chopped macadamia nuts.
Chill dough in the fridge for 1 hour.
Preheat oven to 350°F (180°C).
Using a cookie scoop (I used a regular-sized 4-teaspoon scoop), portion cookies and place on a baking sheet lined with parchment. Flatten each cookie slightly with hands.
Bake 10-12 minutes. They will lightly brown around the edges, but not much!
Allow to cool on a baking rack.
Yields ~22 matcha cookies.
