In a small bowl, mix together the ground cinnamon, ground cardamom, ground ginger, ground cloves, ground nutmeg, and ground allspice to create a chai spice blend.
In a food processor, add the vanilla ice cream, milk, milk powder, vanilla extract, and the chai spice blend.
Turn the food processor on to blend the ingredients for 20 to 30 seconds until smooth.
Pour the chai milkshake into a milkshake glass, finish off with any chosen toppings, and serve immediately.
