I did not do any measurements, but I made my own version with black coffee, couple squirts of hershey's choc syrup and a scoop or 2 of vanailla ice cream. I know Burger King uses their milkshake mix, but have not figured out exactlly what all that is. Anyway, my version turned out well, and it was creamy. Really good so just play with it. Something good will turn out. Let me know if you come up with anything.
