Place the Oreo Cookies in a large ziplock bag. Seal it tightly. Use a wooden spoon to crush the cookies. You do not want them finely crushed, you want them crushed into large pieces for the ice cream.
Then mix together the sweetened condensed milk and vanilla extract in a large bowl.
Pour the heavy whipping cream into a separate bowl and mix with a stand up mixer or hand held mixer for 2-3 minutes until it holds stiff peaks.
Gently stir the whipped cream into the sweetened milk mixture until well combined and be careful not to over mix. Then fold in the Oreo cookies.
Then spread the mixture in a 9 in loaf pan. Cover with foil and freeze for at least 6 hours.
