Marble cake mix recipe w/ cream cheese?

I'm searching for a recipe that uses a marble cake mix %26amp; cream cheese for a ';marbled cheesecake bars'; kind of dessert... It was listed on the back of a cake mix in the early 80's...





I remember that half the yellow cake mix is reserved, while the remaining half is used to make a dough which is pressed into the bottom of a pan and baked, to form a crust. Then the remaining yellow mix is added to the cream cheese (with a few other ingredients) and that mixture is also divided in half. One half is poured over the baked crust; the chocolate mix is added to the reserved cream cheese mixture and then marbled into the pan. After that the whole thing is baked and cut into squares.





My mom used to make this y-e-a-r-s ago and has since lost the recipe. I'm hosting Thaksgiving for my family this year and would love to make this childhood favorite for everyone - if I could only find the recipe!





Does anyone know what recipe this is and where I might find it? Thanks in advance!Marble cake mix recipe w/ cream cheese?
