Open the biscuits and separate them. Cut each biscuit into 4 pieces. Roll each piece with your hands to create balls. You should have 64 balls when you're done. Submerge each ball into the melted butter, then through the cinnamon sugar until they're completely covered in sugar. Place about 1/3 of the balls (20) in a baking dish. Sprinkle with half of the dry cranberries and nuts. Repeat with another layer of 20 balls in the dish. Sprinkle with the rest of the cranberries and nuts. Finish with the last layer of balls.
