Preheat the oven to 180°C (top-/bottom heat) and line baking tray with baking paper.

Pulse the hazelnuts until finely ground and transfer to a medium sized bowl. Add remaining dry ingredients and mix well.

Add water to the bowl and stir well until combined. Scoop the dough onto a sheet of baking paper, place another sheet of baking paper on top and roll out until approx. half a centimeter high.

Use cookie cutter to cut out stars and place them onto baking tray. Knead the remaining the dough to a ball, place on baking paper, cover with additional baking paper and roll out again and cut out cookies. Repeat until dough is finished.

Place tray in oven and bake for approx. 8 to 10 minutes. Let cool down before glazing.

For the glazing, melt ingredients in a double boiler. Then let cool down a little until the liquid becomes thicker again. Use a teaspoon to place a small dollop in the middle of a cookie and pull glazing to the corners.

Let cool down until set. Store in air-tight container in a cool and dry place.
