Hawaiian Cake

I got this recipe from my best friend Cameo. Her dad makes it, and it is so good, especially during the summer.

Hawaiian Cake
1 box yellow cake mix (or I use Duncan Hines Pineapple Cake Mix)
1 package instant vanilla pudding (bigger)
1 carton of Cool Whip topping
1 #2 can crushed pineapple
8 oz. Cream cheese
1 can coconut
Optional: chopped walnuts, about one cup
Directions:
Bake cake in 9 x 13 greased pan (following cake mix directions). 
Remove from oven and pour undrained pineapple onto cake. 
Cool in fridge. 
Mix pudding, milk until thickened, then add softened cream cheese, and blend well. 
Spread over cake, sprinkle with coconut and chopped nuts, and ice with cool whip. 
Refrigerate at least one hour and keep refrigerated afterwards.
