Impossible pies were popular years ago, either savoury or sweet. The magic of these pies was that it formed it's own base and filling. I had made a Broccoli and Cheese impossible pie, but since the recipe required Bisquick or one could make this mix, but the recipe yielded a large amount.
In following a food page on Facebook where handwritten recipes are posted, I came across the two recipes posted below that I used to compare. I like the name of Coconut Custard Pie better.
The third recipe, is what I modified and filled a very large nine inch pie plate. It really didn't need to be done in a Food Processor, as one could easily whisk the ingredients. It did need to be baked at a lower temperature. Also half way through the baking temperature, cover with foil.
