I actually used Jello. This recipe is delicious. Just one problem, the topping. I'm thinking it is suppose to have butter mixed with the topping ingredients or else melted and poured over. After the 30min. I saw how dry the top was, poured 1 cup of melted butter over it, and put it back in the oven for 10min. Next time I will use one of the methods I mentioned above before putting it in for the 30min.
