Add your cashews and plums to a food processor, and pulse until you get a chunky paste (scrape down the sides as necessary). You want to still be able to see some fruit and nut chunks.
Form the paste into bite size balls and place on parchment paper (alternately you could press into a parchment lined baking pan to make bars). The balls are easiest to make if your hands are slightly dampened (makes about 20).
Refrigerate or freeze to set (I prefer mine in the freezer, they do not get solid, but harden up beautifully), either way works fine though!
Store in an airtight container in the fridge or freezer.
Enjoy!
