Grease a springform pan and pour in half of the batter. Spread the fruit on top (as fresh as possible, no canned food) and, in the case of apples, sprinkle a pinch of cinnamon on them.
Make crumbles from the remaining dough and spread on the cake.
Bake on 180 ° C hot air for about 45 minutes or until the crumble is golden yellow. The baking time can vary depending on the oven.
