Method
Make the custard
- Heat the heavy cream and whole milk in a saucepan over medium heat until steaming, not boiling, then reduce to a gentle heat.
- Whisk the steaming cream mixture slowly into the egg yolks and granulated sugar, keeping the stream steady so the yolks don’t scramble.
- Return the mixture to the saucepan and cook over medium-low heat, stirring constantly, until the custard reaches 175F.
Chill the base
- Strain the custard through a fine mesh sieve into a clean bowl, then stir in the vanilla extract and salt.
- Cool the custard completely to room temperature, then refrigerate at least 4 hours until very cold.
Churn and freeze
- Churn the chilled custard in an ice cream maker according to the manufacturer’s instructions.
- In the last 2 minutes of churning, add the roughly crushed chocolate sandwich cookies, letting some chunks stay intact and some dissolve for a cookies-and-cream swirl effect.
- Transfer the churned ice cream to a container and freeze until firm.
Notes
For the smoothest custard, cook only until it hits 175F—once it coats the back of a spoon, pull it from the heat and strain right away. Refrigerate leftovers up to 5 days; for best scoopable texture, freeze well in a sealed container up to 2 months. For a lighter option, use reduced-fat milk and keep heavy cream at 1 cup, though the texture will be slightly less rich.
