1. Blitz the CORTINA Ice-cream, KEFALOS Fresh Milk and vanilla essence in a blender until combined and creamy. Pour into a large jug.
2. Dip the rims of four glasses in the melted white chocolate, then some sprinkles, if you like. Leave to set slightly, then divide the milkshake between the glasses. You can customise your shake with different toppings, such as mini cookies, marshmallows, pretzels, sweets and squirty cream.
