Add peanuts to the bowl of a food processor and process for 1-2 minutes. Open the lid and scrape the sides. The mixture will be grainy.
Continue blending for another minute. Open and scrape the sides once again, season with salt and maple syrup.
Blend for 2-4 minutes until silky smooth in consistency.
*If you like your peanut butter chunky, reserve ¼ cup of peanuts, coarsely chop them or lightly process in a food processor and mix in with the smooth batch.
