Add cashews to bowl of food processor and process. After 2-3 minutes as the cashews form clumps, stop the processor and scrape down the sides.
Continue processing. As the mixture evens out, add in melted coconut Continue processing until it turns smooth.
Add in melted chocolate chips and sea salt, if using. Process for 1-2 more minutes, until chocolate cashew butter reaches desired consistency.
Notes
*I used unsalted cashews and added 1/8 tsp of sea salt. If you use salted cashews, you may not need the salt. I used a 9 cup Kitchen Aid food processor.
