Whisk eggs with sugar until creamy. Add the oil and the yoghurt you made from Efeler Çiftliği Milk. Sift flour, semolina, baking powder, and vanilla into the mix and blend with the mixer on low speed. Lightly grease an oven dish, sprinkle it with sugar and pour the mixture in. Bake in over pre-heated to 200°C until the top and bottom turn pinkish gold. Meanwhile, prepare your syrup until it reaches a semi-thick consistency, cool it completely and pour over the baked mixture while it is still hot. Cover. Serve when the dough soaks up all of the syrup.
