Chop the Oreos and the chocolate bar into bite sized pieces.
Pour the sweetened condensed milk into a large bowl.
Stir in the vanilla extract.
Stir in the chopped Oreos and chocolate.
Pour two cups of cold heavy whipping cream into the bowl of a mixer fitted with a whisk attachment.
Beat the cream at medium high speed until stiff peaks form (about two minutes). Stiff peaks mean that if you remove the beater with a bit of cream on the end and flip it upside down, the cream will keep its shape.Remember: over beating cream will turn it into butter, so be sure that you are watching carefully.
Gently fold the whipped cream into the sweetened condensed milk. Start with one large spoonful at a time. Do not over mix.
Pour the mixture into a glass or metal loaf pan. You can also use a square glass pan.
Cover with plastic wrap and place in the freezer.
Freeze until firm, about six hours.
