What is Peanut er made with?

Most of them don't contain any animal ingredients. Usually just peanuts and salt and sometimes hydrogenated oils and added sugar. Nutella has milk but that's not a peanut er. Some or all of the Peanut er & Company are vegan. If you want to avoid hydrogenated oils (not an animal product but not great for your health) try an all natural variety. Skippy Natural and Smart Balance are not hard to find and they don't need refrigeration or stirring like some of the health store brands.
