I was looking for the recipe also, and found your post. I finally found the recipe from www.eat.at from another blog posting from "brook": Here it is!!!
I think this is the recipe that all of you are looking for. It is a personal favorite of mine as well, but I 'll be darned if I threw the box side away that I was saving that had the recipe on it. It came off the side of a Pillsbury lemon cake mix. Anyhow, this is it. I've tried substituting other brands, while using the same recipe, but it just isn't the same. It is wonderful.
Hope this helps.
Ingredients:
1 pkg. Lemon cake mix (Pillsbury tastes best)
1 Stick of butter, melted
1 Egg
1 can lemon frosting
2 Eggs
8 oz Cream cheese, softened
Instructions:
1. Mix first 3 ingredients together to a crumbly texture. Set aside ¾ cup. Pat remaining mix into the bottom of a 13 x 9 pan. 2. Mix together the frosting, eggs, and cream cheese. Spread evenly over cake mix. Sprinkle top with reserved ¾ cup cake mix and bake at 350°F for 40 minutes. Keep refrigerated
