Not made this for a while but it is lovely - I use a tbsp of flavoured syrup in mine instead of the vanilla - Put the condensed milk, cream and vanilla into a large bowl. Beat with an electric whisk until thick and quite stiff, a bit like clotted cream. Scrape into a freezer container or a large loaf tin, cover with cling film and freeze until solid.
im thinking this style of cake for ellie, but decorated with candy. Have the main frame pink lemonade cake, the towers out of rice kripsy treats, with a gumdrop path. The tower roof will be an ice cream cone covered in frosting and rolled in sprinkles. Other candy: twizzlers, lots of pink candy
