Mix well the flour, baking powder, spices, then knead in the butter (with your fingers) until a crumbly mixture is formed. Now add the fruits, milk, eggs, orange peel and the chopped apple and mix everything to a smooth dough (results in a consistency similar to a sponge cake)
Put the dough in a greased springform pan or flat, round dish and smooth it out. Bake at 180 ° for about 30 minutes. Enjoy lukewarm as a dessert or cold as a cake!
