Make the base: Add the vanilla to the cream (if using) and whip the cream to stiff peaks.
Flavor: Fold in the chopped cookies and sweetened condensed milk.
Freeze: Add the ice cream to a loaf pan. Cover the ice cream with plastic wrap to minimize ice crystals forming on top, pressing the plastic into the surface. Freeze for 6 hours or overnight. See notes.
Serve: Let the ice cream sit at room temperature for 10 minutes before serving to make scooping easier.

Notes
Stiff peaks: Cream is whipped to stiff peaks when you can hold a dollop up and the point stays standing up and doesn't bend over. If it bends over this is at soft peaks. You need stiff peaks for no-churn ice cream.You can whisk the cream by hand using a whisk it just takes longer.Freeze for 6 hours for a soft-serve consistency.Freeze overnight for a hard ice cream consistency. This is my preference.Try a different Oreo flavor to switch things up.
