Robust porter help

I’ve never made a porter before and looking for a complex creamy recipe. I recently made an oatmeal stout and it turned out more like a thin dry stout, and looking for something with some more mouthfeel. I found this recipe and was wondering if anyone has made it or something close and if it may be close to what I’m looking for. I think it is based on one of Denny’s recipes. I was thinking of mashing at 154.
Also, would anyone recommend adding some black patent?
–thanks
