For the filling, wash, peel, and grate the apples.

Add them to a pot, then add sugar and mix.

Set aside while you prepare the rest.

Grease and flour a biscuit tin measuring 21 x 36 cm (9 x 13 inch).

Add baking powder to the flour and mix.

In another bowl, add eggs, sugar, oil, milk, and prepared flour.

Mix everything with an electric mixer.

Spread half of the mixture into the prepared pan.

Place in a preheated oven at 350 degrees for 15 minutes.

During this time, finish the filling.

Put the apples to cook at a medium temperature.

As soon as they start to boil, add semolina and cinnamon, and cook for another 2-3 minutes.

Spread the filling over the baked biscuit.

Immediately shake out and distribute the remaining part of the biscuit mixture.

Return everything together to the oven for another 25-30 minutes.

Leave the baked cake to cool.

For decoration, sprinkle powdered sugar on the surface of the cake.

Cut into equal squares and serve.
