Preheat oven to 350 degrees. Take cake mix and fix according to box directions. I used the pineapple juice for the water called for in the cake mix. Spray a cookie sheet or 11x16 pan. Bake for 13-15 minutes or until cake is done. Let cake completely cool.
Now combine vanilla pudding, cream cheese, and 2 1/2 cups of milk. [I used the pineapple juice I had left to substitute for the milk. I had 2 cups left, then I added the 1/2 cup of milk] Spread that mixture over the top of the cake.
Then we layered the Bananas on top of the pudding.[Sprinkle a small amount of lemon juice on the bananas so they won't turn brown] Then you layer the crushed pineapple on top of that.Then you apply cool whip over the top. Then you apply coconut and marachino cherries to the top.
