Using a stand mixer fitted with the whisk attachment, or in a large mixing bowl using a hand-held mixer, beat the cream cheese until smooth. Add in the the icing sugar and vanilla extract and mix until well combined.
Pour the double cream in a separate bowl. Start mixing on low speed, then increase the speed to medium-high until the mixture thickens and stiff peaks form. Add the whipped cream to the cream cheese mixture and gently fold it in or mix it in on low speed with your mixer until just combined. Then, fold in the chopped Oreos.
Remove the spring form pan from the refrigerator, scoop the cheesecake filling onto the crust, and carefully spread it around into one even layer. Then add your remaining Oreos to the top of the cheesecake. Cover tightly and transfer back to the refrigerator to chill for at least 4-5 hours or overnight. Remove the no-bake cheesecake from the pan, slice and enjoy!
