Place cranberries and oats in food processor fitted with metal S shaped blade. Pulse until coarsely ground. Add coconut flakes, raw cacao, vanilla extract, salt, honey, coconut butter and pulse to combine, until the mixture comes together. If the cranberries or coconut butter are very dry you may need to add a tablespoon or more of warm water. Place mixture in a bowl and fold in cacao nibs. Consistency should be slightly sticky and easily form into balls. Roll mixture into small walnut sized balls, (or larger depending on how you like them). If the mixture is sticking to your hands, lightly moisten hands with water. Serve as is or sprinkle with cacao powder. Store in a covered container in the refrigerator.
