Process the almonds in a food processor until coarsely ground. Add the oats, dates, coconut oil and cacao powder and process until the there are small flecks of nuts and oats and you have a consistent texture.
Roll a heaping tablespoon into the palm of your hand into a ball. Depending on the kind of dates you use you may need more moisture. If the ball does not hold together, put the mixture back and add a tiny splash of water or a little bit more coconut oil. If it is too wet add a little more cacao powder.
Toss the balls into the cacao powder to coat and tap the excess powder off. Store in the refrigerator.
