I saw several recipes for Pumpkin Dump Cake. I tried one of them. And then thought how much my diabetic friends would love this. . .so, I have done a little tweaking. This is what I came up with. This cake is great to make the night before, because it just gets better and better!! If you are not diabetic. Just substitute the Ideal or Splenda with regular sugar and use a regular yellow cake mix. The first time I made this, I used a spice cake mix. Enjoy!!
