Add all ingredients to food processor and combine until desired consistency, scraping down sides as necessary.
Add additional canola oil 1/2 tsp at a time as necessary to help smooth out the peanut butter at the end, and add sea salt to taste if using unsalted peanuts.
Store tightly covered in refrigerator.
You can use your handy-dandy food processor to make other nut butters the same way. Or make yourself chocolate peanut butter by leaving out the cinnamon and adding in a little melted dark chocolate + vanilla — or why not scratch up some tasty and allergy friendly sunflower seed butter?
