Place 9 oreos in a blender or food processor and pulse until you have small crumbs and set aside.
Crumble 9 oreos into small pieces with your hands, or place in a ziplock bag and crush with a rolling pin and set aside.
Add the whipping cream and vanilla to a large bowl. Beat with a hand mixer just until it begins to thicken.
Add the condensed milk and continue to beat until soft peaks are beginning to form.
Fold in the crumbs, followed by the crumbled oreos.
Pour the mixture into an 8x4 loaf pan.
Break the remaining 9 oreos over the top of the ice cream, or decorate with whole oreos.
Place in the freezer for at least 8 hours, or overnight to freeze.
Scoop and serve as desired.
