Chill a large mixing bowl and the beaters of an electric mixer (or whisk attachment of a stand mixer) in the refrigerator for about 15 minutes. Remove from the refrigerator and pour the whipping cream into the chilled bowl. Beat on high speed until stiff peaks form.

Gently stir in sweetened condensed milk and chocolate syrup until mixture is well combined. Fold in crushed Oreos.

Spoon into a freezer safe container, cover, and freeze for about 4 hours or overnight.
