Pit and chop the dates. Place matcha powder in a medium-sized mixing bowl and set aside.
Combine the almonds, oats, and cocoa powder in a food processor and pulse until evenly distributed.
Add the dates, vanilla extract, maple syrup, and 1/8 cup of the soy milk. Pulse until the mixture is formed. After adding the first 1/8 cup of soy milk, add 1 tsp of soy milk at a time until the mixture is moist enough to roll, but not too wet where it is constantly sticking to your hands.
Roll the dough into ~1 inch size balls and place in the mixing bowl with the matcha green tea powder.
Shake the bowl to coat the balls with the powder. Serve immediately or refrigerate/freeze for later use.
