Mix the flour, baking powder and 1/2 teaspoon salt. Use a pastry cutter to cut in the shortening. Add the 2/3 cup milk and make a dough by kneading it with your hands. Press this dough out flat in a casserole dish that you greased first.
Use a nonstick skillet in which to melt the butter and add the onions. Sauté this until the onions begin to turn golden or light brown. Take off the heat and let the onions cool. Make a layer of the sautéed onions on top of the dough.
Beat the egg, cream or condensed milk and the teaspoon of salt. Pour this over the onions in the casserole.
Bake at 400 degrees for 15 minutes or a little longer. If you wish to add one of the cheese options, sprinkle over the top of the dish for the last 5 minutes of baking time.
Slice into serving-size pieces and lift out of the casserole with a spatula or cake lifter. Enjoy this every now and then even when the temperature isn’t below freezing.
