A family member mixed sunflower butter, cocoa, sugar and a bit of milk (stirred in, not thoroughly mixed in) and left it in the fridge for quite a long time, a month or so. I want to wash it out but this isn't any sort of botulism risk is it? If it is it would be very hard to clean and I would rather throw out the bowl. I still am confused about leaving something fatty with something else and thinking that it's coating whatever it's mixed with and getting sort of anaerobic. I don't understand why nut butters don't have a problem either but it seems they don't. I know there are commercial chocolate nut butters but I assume they are pasteurized and processed together making them safe.
I did read this question but am still confused. Chocolate and oil mixed
