As you know, I have been making my own jam/preserves and learning that making homemade nut butter is also very easy hence I set it out to give it a try. My girls loved Nutella so I added cocoa powder into my experiment. It didn't taste very good at first so I tried adding some brown sugar and gave it a taste. It also felt a bit thick so I added a little peanut oil to make it smoother and the above was the result of it.
We really liked it and when I am out of the almonds, I might try it with peanuts since peanuts is a lot cheaper. I bet you can experiment with different nut for a different nut butter taste as well. Happy trying!
