These were very delicious, but also very sweet (which I happen to love, but not everyone might). It may have been because my canned sweet potatoes had been packed in syrup - if yours are too, I would recommend reducing the white sugar probably by half, or maybe completely eliminate. I subbed Splenda for the white sugar, and only used about 1/3 c. margarine for the topping. Also used 1/2 c. egg substitute for the egg whites, and the consistency probably was not as firm as it should have been. Still made for delicious eating, however. The oatmeal adds a wonderful crunch!
