For the dough, warm milk lukewarm. Crumble yeast into it and dissolve while stirring. Mix 250 g flour, 50 g sugar, cocoa and 1 pinch of salt. Add the egg. Add yeast milk. Stir in with the dough hooks of the mixer while kneading 75 g soft butter in flakes.
As soon as the dough forms into a ball, continue kneading for about 3 minutes. Cover and leave to rise in a warm place for about 1 hour until its volume has doubled.
Knead the dough briefly on a little flour. Form into a roll on a well floured work surface. First cut into about 15 pieces and then shape them into balls. Press each ball flat one after the other (approx. 8 cm Ø).
Place approx. 1⁄2 TL jam on each. Pull the edges of the dough over the jam and close.
Place filled dough balls on a greased baking tray with the seam facing down. Cover and leave to rise in a warm place for about 20 minutes.
Heat the frying fat in a deep fryer or a wide pan to 160-170 °C. Deep-fry 4-5 balls in each pan for approx. 6 minutes, turning them carefully with a skimmer. Lift them out and let them drip off briefly.
Immediately roll in about 150 g sugar and let it cool down.
