Preheat the oven to 375 F or 200 C

Flour a work surface and roll the pastry to around 1/4 cm thickness.

Using a knife or pizza cutter, cut even rectangles of dough, around 3 by 5 inches work well.

Place the dough on the baking tray- lined with parchment or aluminum foil that has been lightly floured.

Spread 1 tbsp of Nutella on one rectangle leaving a 1/2 centimeter periphery and sprinkle on a pinch of cinnamon (1/8 tsp) evenly.

Brush this periphery with heavy cream or egg wash (1 egg beaten with 1 tbsp water).

Place a bare rectangle directly on the one with Nutella and press the edges gently. Then, taking a knife, cut the edges to create sharp, straight ones.

Using a fork, gently press the edges of the rectangle to create a pattern.

Brush the tops of all the rectangles with heavy cream and sprinkle with granulated sugar for a nice shimmer.

Bake for 10-15 min until golden brown and drizzle with the glaze.

For the glaze, combine all the ingredients together until smooth, place in a ziplock bag and snip of the end to drizzle. Or you could just spread it with a knife of back of a spoon.
