In a large mixing bowl, pour in the heavy cream. Using an electric mixer, beat the cream on high speed until it forms stiff peaks, which should take about 3 to 5 minutes. Keep an eye on it to prevent over-whipping.
In a separate mixing bowl, combine the sweetened condensed milk, vanilla extract, and a pinch of salt. Stir gently with a spatula until all ingredients are thoroughly mixed.
Carefully incorporate the whipped cream into the condensed milk mixture. Use a spatula to fold the whipped cream in gradually, ensuring you maintain the lightness and fluffiness of the whipped cream.
Once the mixtures are combined smoothly, gently fold in the crushed Oreo cookies, making sure to save a few for garnish later.
Transfer the delightful mixture into a loaf pan or an airtight container, smoothing the surface for an even finish.
Sprinkle the reserved Oreo crumbles generously on top of the mixture. Seal the container tightly with plastic wrap or a lid to prevent freezer burn.
Place in the freezer and allow to set for at least 6 hours until it becomes firm and scoopable.
Notes
For an extra touch of decadence, drizzle with chocolate sauce and top with an additional Oreo cookie.
