Preheat the oven to 350 degrees Fahrenheit.
Once ready, add the pumpkin seeds to a baking sheet and bake for 15 minutes.
Remove from the oven and transfer to a food processor with the salt.
Add in any of the optional ad-ins. I used coconut oil, cinnamon and vanilla.
Process for about 20 minutes or until completely smooth. You'll likely need to scrape down the sides every 5 or so minutes. It will go through a few phases and you might think you're not doing it right because it won't look anything like nut butter for a while, but be patient! It'll start dry, then form a ball, keep scraping down as needed and process until it's nice and smooth & runny.
Generally speaking, the longer you process it, the smoother it gets so don't be afraid to let your food processor run!
Transfer to an air tight container and store in the fridge.
