Preparation
Wash and dry fruit. Mix flour, baking powder, sugar, salt, eggs and soft butter in a bowl and knead the dough until creamy and firm.
Put the dough into a cake tin of 20x30 cm covered with baking paper with the help of a dough scraper.
Peel apple and cut into thin slices.
Cover the dough with apple slices and berries. Bake in the preheated oven at 180°C (top/bottom heat) for about 30-35 minutes (make the toothpick test).
Let cool, cut into large squares and serve.
Suggestion
Due to the fresh fruit you can keep the cake at room temperature for just one day. Alternatively, you can cover it and store in the fridge for up to 3-4 days.
Take the butter out of the fridge at least one hour before preparation. Alternatively, you can also use the defrost function of the microwave.
