Mix all cake ingredients. Bake at 350 degrees F for 35 minutes. Chill.
For Icing: Mix first four ingredients and cook until thick. Add coconut. Cool slightly and spread on cold cake. Keep refrigerated. Freezes well.

This cake sounds so good but I live in Middle Georgia and have never seen sour cream cake mix or pineapple pudding. What are the brand names? Thanks.
