With a wooden spoon mix all the ingredients together in a large bowl. You want the consistency to be firm and all the ingredients to easily stick together. If you try forming a ball and it all keeps falling apart, add more nut butter and honey. If the consistency is too wet, add a spoonful or two of oats. A trick I like to use is to put the whole bowl in the fridge for 30 minutes to firm things up. This will make it much easier to form into balls.
