Put the milk in the bowl of the mixer. Add the sugar and mix until the sugar is dissolved, about 3 minutes.
Add in the cream, vanilla, and vanilla bean.
Pour the mixture into the ice cream machine. Follow the directions that came with your ice cream maker. Mine says to turn it on and let it go for about 25 minutes. If you are adding in Oreos, wait until the last 5 minutes to add them to the machine.
Let the machine do its thing.
Put the ice cream into a container and put it into the freezer to continue freezing.
