Like "I have a recipe similar to this in my file. The recipe is about the same only you use one small. box of sugar free butterscotch,1small box of vanilla pudding. I can of pumpkin (not the pie filling) and 3 cups of skim milk. Pumpkin pie spice. Blend together and put in the fridge. Use sugar free cool whip(small). Now she blended this in the mix. It makes a lot. I don't see why you couldn't just put the cool whip between the layers. I never made it, because I do not like pumpkin."
