I will email you the recipe because it is likely you have everything, and it is surprisingly amazing stuff for the sum of its parts, but you may or may not need to really homogenize your kind of peanut butter for it to do anything not-unattractive when it hits lukewarm white [melted cocoa butter product of choice].

Our peanut butter is Teddie's which needs to be homogenized every time you take the lid off, so I suspect we will manage. spatch has been using it for cookies and even penuche variants quite successfully. (His best penuche variant is basically just maple.)
