1. Place all ingredients in a large bowl and beat with an electric beater until fluffy, thick and shiny. Divide into three bowls and colour each one a single colour to desired tones.
2. Separate icing into 3 small bowls using 1x 1/4 cups to make red, 1x 1/4 cups for yellow and 1x 1/4 cup for black. Add food colour to each, and mix to get desired tones.
3. Spoon into a piping bag or you can use a small ziplock plastic bag with a small hole cut out of the corner. Pipe onto biscuits for decoration.
4. Ice with piping bags and decorate to look like Santa’s belly and outfit. A black line for the belt, a yellow rectangle for the belt buckle and white confetti for his buttons.

Note: Icing contains raw egg whites - not suitable for those on restricted diets.
