Add cashews to food processor and process for 1-2 minutes. Scrape down the sides and process again. Continue to scrape down sides every few minutes until about 12 minutes have passed. Let the food processor run until the cashew butter is very creamy. If this is your first time, add one more minute to when you THINK it is down. I promise it can get creamier!
Store in a mason jar in the refrigerator for up to 4 weeks.
