Drain the apricots well, chop them into small cubes and dust them a little with flour. Cut the chocolate into small pieces. Grease the muffin tray well and sprinkle with flour.
Mix flour with baking powder and possibly baking soda. In a second bowl, stir together sugar, vanilla sugar, yoghurt, oil and orange flavor until the sugar has dissolved. Mix in the flour mixture with a spoon until it has combined with the moist ingredients. Finally fold in the chocolate chips and the apricot cubes.
Pour the dough into the molds and smooth out. Bake at 180 ° C top / bottom heat or 160 ° C convection for 25 - 30 minutes. Let cool and dust with powdered sugar.
