Simplest and easiest recipe using just one ingredient: Peanuts!
You can customise it as you want, I bought raw peanuts and roasted them myself.
I only added a bit of salt, brown sugar and honey to flavor mine but it is just as good without any additions.
The honey I added to my peanut butter changed the consistency to what can be seen at the end which is thick. Omit the honey if you want runny PB. Enjoy 😁
