I totally understand where you are coming from.
That most famous Nordicware Tunnel of Fudge recipe came in second in the 17th Pillsbury Bake-Off Contest in 1966.
I have always felt that the baker was SusanLucci-ed out of a solid victory.

The grand prize in the contest went to a bread made with cheese spread and dry onion soup mix.

(Is there any chance of getting you to share your recipe?
There is no way on earth it can even stoop to the level of the boxed cake. And, if past history is any judge, you may yet have a solid winner on your hands.)
