01 - Place roasted peanuts into a high-speed food processor or blender.
02 - Process for 1 to 2 minutes, pausing to scrape down the sides, until peanuts form a coarse, crumbly mixture.
03 - Continue blending for an additional 2 to 4 minutes until the mixture becomes creamy and smooth.
04 - Add sea salt and sweetener to taste, then blend until incorporated. For a thinner consistency, blend in oil 1 tablespoon at a time until preferred creaminess is achieved.
05 - Spoon peanut butter into a clean, airtight jar. Store at room temperature up to 2 weeks, or refrigerate for extended shelf life.
