Place Oreo cookies in a Ziploc bag and crush them into coarse crumbs using a rolling pin or a sturdy cup. Set aside a handful of larger Oreo pieces for topping.

In a large mixing bowl, pour in the heavy whipping cream. Using a hand mixer or whisk, whip the cream until stiff peaks form. This should take about 3-5 minutes.

Add sweetened condensed milk, mixing until the cream and condensed milk are fully combined and smooth.

Fold in the crushed Oreo crumbs, leaving the larger pieces aside for topping. Transfer the mixture into a loaf pan or any freezer-safe container.

Sprinkle the reserved larger Oreo pieces on top for a fun texture. Cover the container with plastic wrap or a lid, and freeze for at least 6-8 hours or overnight.

When you're ready to enjoy, let the ice cream sit at room temperature for about 5-10 minutes to soften. Scoop into bowls or cones.

Enjoy your homemade Oreo treat!
