Make a batter from flour, sugar, mineral water, oil, eggs, baking powder and vanilla sugar. Spread half of the dough on a prepared baking sheet. Spread the fruit on top and cover with the rest of the batter. Bake in a preheated oven at 180 ° C for about 35 minutes.
I like to use cherries and mandarins as fruit, but you can also use just cherries, only mandarins or apricots or peaches.
