Peel and dice the apples, pour the lemon juice over them and mix to prevent the apples from oxidizing, put them in the fridge.
Preheat the oven to 180ºC and line a baking tray with non-stick paper and grease with butter.
Separate the egg yolks from the egg whites, whisk the egg whites until stiff.
Add the egg yolks, sugar and butter and whisk it all until creamy.
Add the flour, cornstarch, yeast and salt, mix again.
Then add the egg whites and mix well without whisk, just fold it in, then sprinkling a bit of flour on the apples and add the apples to the batter and pour everything into the baking tin.
Bake for about 45 minutes until the cake is cooked through, prick it in the center with a toothpick, if the toothpick comes out dry then the cake is baked, bon appetit!
