Method
Make the vanilla custard
- Heat the heavy cream and whole milk in a saucepan until steaming, not boiling. Keep the heat steady so the dairy warms evenly.
- Whisk the steamed dairy slowly into the egg yolks and granulated sugar. Pour gradually while whisking to prevent scrambling.
- Return the mixture to the saucepan and cook over medium-low heat, stirring constantly, until the custard reaches 175F. Scrape the bottom and corners to avoid overcooking.
Chill the base
- Strain the custard through a fine-mesh sieve into a clean container. Use the back of a spoon to press through the custard for maximum smoothness.
- Stir in the vanilla extract and salt, then let the custard cool completely. The surface should look glossy and smooth before chilling.
- Refrigerate the custard for at least 4 hours, until cold throughout. Chill until it feels thick and scoopable, not pourable.
Churn and freeze
- Churn the chilled custard in an ice cream maker according to the manufacturer’s instructions. Stop when it reaches a soft-serve consistency.
- In the last 2 minutes of churning, add the crushed chocolate sandwich cookies. Fold just enough to create a cookies-and-cream swirl—some pieces will stay chunky and some will dissolve slightly.
- Transfer the ice cream to a container and freeze until firm. Let it harden so scoops hold shape, not melt immediately.
Notes
For a silkier texture, strain the custard while it’s still warm and stir until smooth before cooling; any lumps will show up after churning. Refrigerate leftovers for up to 3 days (it may soften), and freeze for up to 2 months for best texture. This is not no-churn; for an egg-free swap, replace egg yolks with an approved no-egg base recipe rather than substituting directly.
