Pre-heat oven to 350F (180C). Line a cookie sheet with parchment paper.
Roll out puff pastry and lightly flatten with a rolling pin. Cut the dough into 16* pieces measuring 2 3/4 x 3 inches (7 x 8 cm).
Place a teaspoon full of Nutella on only 8 of the pieces and spread evenly, cover each piece with the remaining 8 pieces, turn them vertically and make thin slits in the dough, leave approximately 1/4 - 1/3 inch (1/2 - 3/4 cm) boarder on the top.
Gently wrap the dough around the top of pretzel stick, place on prepared cooke sheet and gently spread the slits. Sprinkle with sugar and bake for approximately 15 - 20 minutes. Let cool completely before serving. Enjoy.
*This of course depends on how large your puff pastry sheet is, you may get more or less squares.
