Cook time is freeze time. I like to use flavored coffees. I cut the sugar in half and it is still plenty sweet, even to my kids.
- In a freezer-safe bowl, stir coffee and sugar; until sugar is dissolved. Refrigerate until thoroughly chilled.
- Add the milk, cream and vanilla; freeze several hours or overnight.
- Remove from the freezer several hours before serving. Chop mixture until slushy; serve immediately.
- I like to let it thaw 2-3 hours, chop it with a knife until slushy, stir it good and then refreeze it for about an hour and serve.
