Spooky Halloween Doughnuts

Divide the icing sugar between 4 bowls (depending on how many colours you'd like to make.) Add 1 teaspoon of food colouring and 1 tablespoon of water to each bowl, then stir until you have a smooth, thick icing. Add a little more water if needed to reach the desired thick consistency.

Dip each doughnut into the icing, if you're using icing pens to create patterns or designs, allow the icing to set for about 10 minutes before decorating. If you'd like to add sprinkles, sprinkle them over the doughnuts while the icing is still wet, so they stick.
