Cut the prunes into very small pieces. I do this instead of putting them in a food processor, but either way will work. Do it the way you enjoy.
Now put the cut-up prunes into a bowl and then mix in the almond butter and vanilla extract.
Then mix in the walnuts and coconut.
Place some more coconut in a small bowl on the side. Take about 1 tablespoon of the mixture and with your hands roll into a ball.
Then roll each ball into the coconut.
Now put them into a covered container and refrigerate them for 2 to 3 hours.
These prune power balls can be stored in the refrigerator for a few weeks.
