Preheat oven to 350 degrees F; spray a 13X9 casserole pan with non-stick spray and set aside.
Mix cornflake crumbs, 1 tablespoon of sugar and cinnamon together in a small bowl and set aside.
Cook noodles to package directions; while cooking, mix eggs, sugar, sour cream, and cottage cheese in a large bowl until very well blended.
When noodles are tender, remove from heat, drain and place back in pot; toss with butter cubes until well mixed.
Stir noodles into egg mixture and mix well.
Pour into prepared pan and sprinkle cornflake mixture on top.
Bake uncovered for 50-55 minutes, or until a thermometer inserted in the middle of the dish reads 160 degrees. Let stand for 10 minutes before serving.
