Read the reviews on this one. They all talk about how moist it is with the topping baked in. There's also a recipe from scratch. This one uses a cake mix which were even more popular years ago.

Here is a link that might be useful: Pecan Pie Cake

Boy, it sure sounds like it could be very close with how they are describing it. I was drooling reading it.
I will be trying it for the holiday weekend, and post a review when I do.
Thank you!

You're welcome. Hope it's the one.

How did the cake turn out?

Thanks again for this recipe!

I just made the cake tonight...finally!

Matter of fact it is still hot but I tasted it right away so I could post the results.
It isn't at all what I had years ago, but, it is oooey gooey delicious!
It is kind of wet(just what I like) and sticky, and butter pecany, if any of that makes sense. Like a pecan pie, but not.
I will be cutting it in small squares(very small) and freezing it so I can indulge once in awhile with my tea.
I don't ever want to know how many calories are in this. Ever!
