Preheat the oven to 375 degrees. Beat the eggs with a mixer then add sugar, flour and baking soda. Butter or grease the baking pan. I used a springform pan. Add the chopped apples in the buttered pan. Pour the egg mixture over the apples. Bake about 40 minutes or until set and golden brown. Serve warm or cold. If desired, place in the refrigerator and invert onto platter the next morning and serve with whipped cream or ice cream. Enjoy!
