Turn cherries in flour to the other side. Gently fold into batter along with tangerines.
Fill the dough into a greased cake pan (approx. 2 l capacity) sprinkled with breadcrumbs. Bake in a heated oven (electric oven 175 °C / convection oven 150 °C / gas mark 2) for 55-65 minutes. Halfway through the baking time, cover with parchment paper.
Stir the powdered sugar with the juice of one lemon until smooth. Brush the cooled Gugelhupf with it.
Enjoy baking!
