Put the peanuts and sugar in the food processor, reserving 3 tbs. peanuts if you'd like crunchy peanut butter. Process on high until smooth, drizzling in water until the desired consistency.
Add in the reserved peanuts and pulse a few times to chop them, but not blend them completely. Remove peanut butter from food processor and stir.
