I've made various forms of nut butter including brazil nut and cashew, and the variations including spicy chili and nutella flavors but I've never made "real" peanut butter.
Starting with a cup of roasted, salted peanuts, I ground them into butter with a tsp of Walnut oil in a small Vitamix container.
It was deliciously smooth and salty. Not like Jiff, which is creamy and sweet.
One of my kids tried it and thought it tasted good - phew, one convert.
