not sure what you mean by professional touch? but this is tried and true, been around for almost fifty years that I know of.
The whole blog entry is sort of long, but a fun read. there is a chocolate and an apple version of the cake.
I also had this recipe that made cupcakes-mix cream cheese with a bit of powdered sugar. half fill lined or greased cupcake pans with batter, put a rounded spoon of cream cheese mix on top and finish with another spoonful of batter.
