In a large bowl, mix together the sweetened condensed milk, vanilla extract and crushed Oreos.
Whip the cream until it forms stiff peaks.
Fold half the whipped cream into the sweetened condensed milk mixture, then fold in the other half.
Transfer the mixture to a freezer safe container (you'll need something that can hold about 6 cups). Freeze until firm (4-5 hours).
Scoop, serve and enjoy!
