Mix eggs with sugar, then sift in flour and cinnamon and mix thoroughly until there are no lumps.
Pour in the milk along with the melted butter and stir again.
Peel and core the apples, then cut them into thin slices.
Add the slices to the dough, mix well, and place them on a rectangular baking sheet lined with parchment paper. Pour the remaining dough over the top, sprinkle with nuts, and bake for 1 hour at 180°C. Enjoy!
