How to Make It
Place cashews, salt, honey, and vanilla (if using) into a blender. Starting on lowest speed, blend mixture until crumbly, about 30 seconds to 1 minute. Increase speed and blend about 3 to 4 minutes until smooth and creamy, scraping down sides with a rubber spatula as needed.
Use the rubber spatula to scoop cashew butter into an airtight container. Keep refrigerated.
For best results, make this recipe with a high-powered blender such as a Vitamix or a Ninja. (You can also use a food processor, but the nuts will take longer to break down.)
Can’t find dry-roasted unsalted cashews? Roast raw cashews in the oven at 400 degrees for about 10 minutes, or until fragrant and toasty.
