Pig Pickin' Cake redux

I made one of these this week to share with my knitting class in honor of our teacher's having paid off her home mortgage.   

I was a little out of practice, and relearned a few lessons.  I'll add some notes to the recipe, but in essence what I learned is that without the instant pudding mix to stabilize it CoolWhip will melt and get runny at room temperature.  Since I took the CoolWhip out of the freezer immediately before I mixed in the pineapple/pudding mixture, I had a few bits that didn't get mixed in very well.  My sister suggests moving the CoolWhip from the freezer to the fridge the night before, and also suggests using the bigger box of instant pudding mix instead of the small one the recipe calls for.  

Regarding the name "Pig Picking Cake", it turns out in the South a barbecue is sometimes called a pig pickin'.  This would be a good dessert to take to a barbecue because the Cool Whip won't spoil when whipped cream might.
