Method
Make the custard base
- Heat heavy cream and whole milk in a saucepan until steaming, 2–4 minutes; keep the surface just steaming with small bubbles around the edges.
- Whisk granulated sugar into egg yolks until smooth, then slowly whisk the steaming cream mixture into the yolks to warm them gradually.
- Return the mixture to the saucepan and cook over medium-low heat, stirring constantly, until the custard reaches 175F, about 6–10 minutes; it should visibly thicken enough to lightly coat a spoon.
- Strain the custard through a fine mesh sieve into a clean bowl, then stir in vanilla extract and salt until fully combined.
- Cool the custard completely to room temperature, 30–45 minutes, until no warmth remains and the surface looks smooth.
Churn and freeze
- Refrigerate the custard at least 4 hours until very cold, 4 hours; the mixture should look thick and cold all the way through.
- Churn the custard in an ice cream maker according to the manufacturer’s instructions until it reaches soft-serve thickness, about 20–30 minutes; it should look pale and airy.
- In the last 2 minutes of churning, add crushed chocolate sandwich cookies so some stay chunky and some dissolve slightly for a cookies-and-cream swirl effect; watch for dark flecks spreading through the pale base.
- Transfer the churned ice cream to a container and freeze until firm, at least 4 hours; it should scoop cleanly with minimal melt at the edges.
Notes
For the smoothest custard, keep the heat at medium-low and stir constantly so it thickens evenly rather than scrambling the yolks; a quick visual cue is when it lightly coats the back of a spoon. Refrigerate the custard base (before churning) up to 24 hours, and once churned, freeze for up to 2 weeks for best texture. Freezing yes—once frozen, expect slight hardening, so let sit 5 minutes before scooping. Dietary swap: use gluten-free chocolate sandwich cookies to keep the cookies-and-cream effect gluten-free.
