Place apples in bottom of a greased 8 1/4" x 1 3/4" inch round baking dish. Sprinkle with a mixture of the sugar and cinnamon. Mix dry ingredients together. Combine egg, milk and butter. Add dry ingredients all at once, and mix until smooth. Pour over apples. Bake at 325 degrees for about 1 hour, or until a toothpick inserted in the middle comes out clean. Serve warm. Makes 8 servings. The addition of a handful of black walnuts to the apples makes for mighty good eating!
