Combine the chocolate sauce, golden syrup and food coloring together in a small bowl. Place half of the mixture (just less than 1/4 of a cup) into your blender and set the rest aside for decorating.

Prepare your whipped cream topping by whisking together your cream and icing sugar. Whisk until the cream is thick and fluffy.

Set up a station with 3-4 milkshake glasses , your red blood syrup, whipped cream and any other toppings that you would like to use to decorate.

Add your ice cream, cream and remaining icing sugar into the blender that you added the red syrup to earlier.

Blend until your milkshake is a smooth even consistency.

Drizzle the top inner edge of your glasses with red syrup.

Pour your prepared milkshake into the glasses, avoiding the edges as you pour.

Dollop the whipped cream on top and then drizzle over any remaining red syrup.

Serve immediately.
