Mix flour and baking powder. Add eggs, milk and salt and work into a smooth dough with the whisk of the hand mixer. Heat the cooking fat in a high pot or deep fryer to 180°C.
Pull the apricots and plums individually through the dough, let them drip off a little and fry them in hot fat until golden brown. Remove with a skimmer. Drain on kitchen paper and let cool down a little.
Mix sugar and cinnamon and roll the still warm fritters in it. Let cool and serve fresh. Results in 30 pieces.
