Mug cake sprinkled with apples, incredibly delicious

Now grease a deep baking tray (35 x 24 cm) and sprinkle it with flour. Then sprinkle with a third of the semolina and flour mixture to completely cover the bottom of the pan.

Spread half of the grated apples evenly over the top, then sprinkle the second layer of semolina mixture on top, then the rest of the apples and finish with a final layer of semolina mixture.

Then spread the flaked butter evenly over the cake. Then bake in the preheated oven at 180°C (top and bottom heat) for about 55 minutes until the cake is golden.
Leave to cool a little and, if desired, sprinkle with icing sugar.
