This recipe is inspired by the Powdered Peanut Butter Porter recipe. Even though there was a lot of helpful information in that thread, there seemed to be conflicting opinions about how to impart the chocolate and peanut butter flavor. The procedure I have chosen to follow is to use Smuckers all natural peanut butter (Does anyone have good advice on how to de-oil it?), and to add 2lbs at the end of the boil, and then another pound in the secondary. I will also add 5oz of cocoa powder to the secondary. Other than that, the rest of the process will just be like a regular oatmeal stout.

I have not created a lot of recipes yet, and this is kind of uncharted territory, so input is not only welcomed it is encouraged:mug:
 
I made a Chocolate Peanut Butter Oatmeal Stout using Smuckers Natural Creamy PB and had great results. Mine was an extract beer (not that it really matters I guess). I left the PB sit at room temperature on my kitchen counter and skimmed the oil off the top every day until I felt I had removed as much as I could. Putting it in the refrigerator might help seperation, not sure.

I added 2lbs at 15 min, it wasn't over powering with PB flavor but gave the beer a nice nutty taste I thought. If I do it again I would probably add another lb or 2. Not sure how it would work by adding it directly to the fermenter, I'm interested to hear your results.
 
As far as de-oiling peanut butter, the only method I've seen is to spread it on paper towels and let the oil get wicked off that way.
 
I've been de-oiling 2 jars (2lbs) of Smuckers all natural PB for close to two weeks now. I spread it across a large cookie sheet, and have sandwiched it with paper towels, so far I have changed the bottom layer once, and the top layer 3 times. I'm not too sure how much more oil I can absorb off it. It is too the point where if I grab an end of it and lift up, rather than bend, it will break off.

I am thinking I am going to try and brew this recipe this weekend. Previously I was thinking of adding chocolate to the secondary only, and input about adding some to the boil also?
