Place the milk and sugar in a food blender and blend for about 2 minutes, or until the sugar is dissolved. You can also use an electric mixer or a whisk.
In a separate bowl stir together the heavy cream and the pure vanilla extract.
Pour the heavy cream mixture into the milk/sugar mixture and blend for another minute.
Turn on the ice cream maker, pour in the milk mixture, and freeze it according to the manufacturer’s instructions.
In the meantime crush 2 cups Nilla Wafers. You can put them in a zip lock bag and just roll over them a few times with a rolling pin.
minutes before the ice cream is done, pour the crushed wafers into the mixture through the ingredient spout on the ice cream maker.
Once the ice cream is done, grab an ice cream scoop or a spoon, spread the ice cream on a Nilla wafer, then sandwich it together with another wafer.
