Nevermind. My mother found it. She moved it for safekeeping and then forgot where she put it. Was found in between the pages of a cookbook....where else would it be! Whipped up my cakes and they are now in the oven. So, since I put the request out there, others may be interested in the tip. This is really great for using cake mixes in pans where there is a lot of detail like the Nordic Ware fancy bundt pans (e.g. holiday trees, castle, stadium) or any of the Wilton pans. The cake has a denser crumb and looks/tastes more like it was made from scratch. The cakes are sturdier and can take a little handling.
Using a standard cake mix, substitute 1 cup milk and 3 oz softened cream cheese for the water and oil. Combine milk and cream cheese with the eggs and cake mix and prepare according to the package directions. That's it, so easy and it gives a great result.
Happy Baking!
