In a bowl, add eggs, vanilla extract, and apple cider vinegar and beat well.
Roll aluminum foil and forma cylindrical shape.
Spread the Kunafa dough on a workstation and place the cylinder foil on top. Roll the dough in such a way that it covers the cylinder. Brush the egg mixture on the Kunafa dough and use your hands to seal it in place by applying slight pressure on it.
In a frying pan, add butter and oil.
Once heated, place the Kunafa Rolls and fry on each side until they get a golden brown color.
Remove from the pan and let them cool a bit.
