Combine the flour, hazelnut spread, and egg in a bowl. Mix well and scoop into an icing pouch

Lay the pizza dough out and cut into equal squares.

Squeeze a line of the hazelnut mixture in the middle of a dough square and then roll up to enclose the spread inside. Do this for all the dough squares.

Deep fry the rolled roll-ups until golden brown on all sides and then place on a paper towel to soak up any excess oil.

Sprinkle with cinnamon sugar and drizzle chocolate syrup before serving.
