This is the one I made last year and I've been searching for the last hour!

I've seen threads in other forums about molasses slathered pork butts. They did not cut them, but it was basically an apple juice & apple cider vinegar injection, then slather with molasses and then hit it with rub of your choice. Smoke like normal.
I've slathered butts with mustard and then rubbed before, so I presume molasses serves the same purpose but might enhance the flavor as well.
