Combine dates, almonds, cashews, hemp seeds, vanilla, and the KOS matcha powder in food processor and pulse until well-combined. Mixture should stick together like a dough when pressed. If mixture is falling a part, add a few more dates and process again until combined.
Add cacao nibs and pulse just enough for cacao to be dispersed throughout.

Sprinkle coconut and additional matcha on top and press down with back of spoon.
Place dish in freezer for at least 30 minutes.
Remove bars from dish by pulling out parchment paper.
