Preheat oven to 350F/175Spread sunflower seeds out over the baking sheet and toast for 20-25 minutes (stir halfway through).
Let seeds cool down until warm and add to food processor or high-speed blender. Process/blend until creamy while scraping down the sides every few minutes or so. This takes me around 10 minutes but it can take up to 15 so be patient. Grab a book!
Do not add the coconut sugar and salt until the seed butter is creamy (minimum 10 minutes).
Let the butter cool down and then transfer to a mason jar.
