Heat oven to 350ºF. Line a baking sheet with a silicon mat.
In a large mixing bowl, combine the cashews, honey, and coconut oil. Mix to coat well. Spread the cashews in a single layer on the baking sheet. Bake 15 minutes, stirring halfway though to prevent burning. Remove the nut from the oven and let cool.
Transfer the nuts to a food processor; add the vanilla and salt. Process until a smooth paste forms. (This will take 5-15 minutes, depending on the power of your food processor.)
