Line two cookie sheets with parchment paper. Set aside.
Roll out puff pastry and lightly flatten with a rolling pin.
Cut the dough into 12 pieces measuring about 2 & ¾ by 3-inches.
A pizza cutting wheel is a great tool for cutting the squares and the broom.
How many squares of dough you get will depend on how large the puff pastry is.
You just want to make sure you have an even number of squares.
Place a teaspoon full of Nutella on only half of the squares and spread evenly, cover each piece with the remaining squares, turn them vertically and make thin slits in the dough, leave approximately ¼ to 1/3-inch boarder on the top.
Wrap the dough around the end of a pretzel stick, and place on prepared cookie sheet.
Gently spread the slits.
Brush milk over the puff pastry.
Sprinkle with sugar and bake for approximately 15 – 20 minutes.
Let cool completely before serving.
