I made this up today and it was delicious!
Grease 13by9 cake pan. Sprinkle coconut in bottom of pan.
Mix a white cake mix as box recommends and pour into pan.
Combine one container of lemon frosting with 1 block of cream cheese. (I defrosted the cream cheese in the microwave to make it softer) Thoroughly combine and spoon over top of cake. Marble with knife. Bake until nice and brown and done in center.
I am looking forward to trying this with other variations. Chocolate Cream Cheese sounds wonderful.
