Weigh the ingredients directly into your Ninja Creami tub.
Mix thoroughly to combine, ensuring you have incorporated all the condensed milk.
Place the mixture into the freezer without the lid for up to 24 hours. I find around 15-16 hours is enough for me, but your freezer might be warmer or colder.
When you are ready to use it, process your ice cream using the ice cream function. If it looks a bit balled up after the first spin, spin it again.
Serve alone, with mix ins or with a dessert of your choice. You can place the lid on leftovers and process again when you need more vanilla ice cream. The Ninja Creami machine will successfully spin a half tub. If it is only a few hours later, I find you don't need to respin this recipe - it remains creamy and scoopable.
