This has got to be the easiest thing to make -- possibly easier than toast... Once you've made it fresh, you'll never buy peanut butter at the store again!
Put ingredients in food processor.
Turn it on.
As it blends, the mixture will form into a ball and then slowly break down and become creamy. Stop when the ball has disappeared.
For crunchy peanut butter: Add a 1/2 cup of peanuts to the creamy peanut butter already in the food processor and pulse until the desired chunk size is reached.
