Grease the muffin tin and preheat the oven to 180 ° (convection 160 °). Drain the cherries well.
Mix flour with baking powder and baking soda. In a second bowl, beat the egg with sugar until frothy and stir in the vanilla sugar, oil and yoghurt. Then carefully add the cherries. Fold in the flour mixture, pour the dough into the molds and bake - immediately if possible - for 20-30 minutes.
