Add the cashews, salt, and sweetener (if using) to a food processor. Process all of the ingredients. While processing, drizzle the melted coconut oil down the pipe. This will help mix and create a smooth consistency much quicker.
When ready, transfer to a jar with a lid.
Enjoy right away.
Cashew butter like most nut butter will harden if refrigerated. Simply microwave the cashew butter for a few seconds to soften it.
