Add butter, nutella and sugar in a mixing bowl and mix well.

Now add all purpose flour, milk, salt, ginger powder, cinnamon powder and mix well with your hands to make a soft dough. Freeze it for 15 minutes.

Flatten the dough to 1/3 inch thickness with rolling pin, sprinkle some sugar on top and cut it with cookie cutter.

Keep at least 1/2 inch distance between each cookie.

Preheat oven at 180 C/350 F.

Set the timer for 12 minutes and place the cookie tray for baking at the same temperature.

When the edges start turning golden brown, remove from the oven and place them on wire rack for cooling. When they have completely cooled, decorate the cookies with royal icing. Use the smallest nozzle for decorating cookies. Leave them on wire-rack for 20 minutes before storing them in cookie jar.
