Better than Sex Yellow Cake

My pix are out of order but you can pretty much tell which goes where and the ingredients used.

It's pretty simple you will need:
Bannas (about 2 or 3)
Box of yellow cake mix
can of crushed pineapple
coolwhip
cup of sugar
walnuts (pecans or cashew)whichever you like best although I prefer the walnuts I never made it with any other kind
13x9 size pan
vanilla pudding

Bake the yellow cake you know just like you make a regular cake.Wait till it cools poke holes in the cake with a fork. Pour the can of crushed pineapples in a pot and the cup of sugar bring your crushed pineapples and the cup of sugar to a slight boil. Then pour it on top of the cake (the whole pot don't pour off the juice it's going to make the cake so moist) Then Spread the vanilla pudding on top of the pineapples. Then cut up the bananas in like slices over the whole cake on top of the pineapples. Then on top of that spread the cool whip on top of the bananas. Then to garnish sprinkle the walnuts on top of the cool whip and dada you have it.
