This is my second attemp at making something using leftover pie pumpkins from Halloween. This is not something I would have thought of trying without the help of Google.
I used the following recipe. You will note that it calls for canned pumpkin. I made my own puree using the pumpkins we had here and it worked just fine. It may have also made the recipe healthier.
I also cut back on the amount of sugar, opting for 1/2 cup instead of 3/4 cup. My kids certainly did not notice the difference as they still enjoyed it.
