In a food processor or blender, combine the chickpeas, peanut butter, sweetener, vanilla, salt, and 2 tablespoons of milk.
Blend until completely smooth, scraping down the sides as needed. If the mixture is too thick to blend, add another tablespoon of milk.
Serve and enjoy: My favorite presentation is the classic peanut butter cookie look with the cracked edges and the fork crosshatching with a sugar/salt dusting on the surface. Store leftovers in an airtight container in the fridge for up to 5 days.
