Soooo yummy! These were really easy to make other than the time it takes to cook and bake it's a quick mix up desert. I didn't have margarine, I only had butter but that's the only thing I substituted.They had a great creamy pumpkin flavor, nice texture and easy cutting.They also had a nice balance of flavors, nothing overwhelmed the other. I know I'll make them again! Thanks for another great recipe to add to my household.
