I'd never heard of such a thing but it looked good so I made it. It is very good, especially with a little whipped cream on top. Wife loved it, I made another the next week, added a little cinnamon to it and it was even better. So simple to make. She asked me to not make another one for a bit because she is trying to stay on a low carb diet and if that pie is in the fridge she can't stop herself.
